B. Group level - The hydraulic engineering group
The hydraulic engineering group covers areas within hydropower engineering, hydrology and hydraulics. The research profile of the group includes both basic research particularly in the field of computational fluid dynamics, and applied research and development. In many areas the applied part is of great importance and a close relationship between the research group and consultants and authorities using the results for practical applications exists. The group has three professors, one associate professor, one assistant professor, two adjunct associate professors and a research scientist. The six PhD students (at this time) make a very important contribution to the research in the group.


  1. Description of research activities

An important research area for the group is hydraulic analysis of sediment loaded rivers and reservoirs, and design and development of water diversion structures in these rivers. Areas of research cover design methods, data collection and 3D simulation of water flow, sediment transport and floating debris and ice in scaled laboratory models. Physical hydraulic models are the best tool for conceptual studies, hydraulic design and optimisation of head-works at run-of-river hydropower plants in sediment loaded rivers. The group operates a physical hydraulic laboratory (the only one of its kind in Norway) that is used for basic research and applied contract research as well as for education.

Optimum sediment handling at run-of-river hydropower plant is an important ongoing research programme. This involves development of real time sediment measurement techniques and the process of efficiency loss as a function of sediment induced wear of turbines.

The group is involved in research on dam safety, emergency action planning and flood handling issues related to dams. Two PhD studies in this field of research were finished in 2002 and group members are active in the International Commission on Large Dams both on a national and international level. A new adjunct professorship is planned to cover the topic of rehabilitation and upgrading of hydropower plants (including dams), a topic of increasing importance both in Norway and internationally. Group members have been involved in both laboratory studies as well as field tests of dam stability and dam breaching.

A main research activity is 3D CFD modelling of water and sediment flow in rivers and reservoirs. The main focus is presently modelling the formation of meandering channels, starting from a straight channel. This involves some basic research on channel bends, secondary currents, roughness prediction methods, sediment transport on a sloping bed etc. Our CFD work also involves hydraulic structures, like bridge piers and intakes. This includes computation of maximum local scour depth around bridge piers and determination of coefficient of discharge for a spillway. Numerical modelling techniques are applied in analysis of hydraulic structures and in computing sediment transport in intakes and determination of local head loss coefficients. Results from laboratory tests or field observations are required in order to calibrate and verify the numerical models.

Cold climate hydrology and hydrology of snow and ice has been an important topic for the group. Within the area of snow and ice research is focused on snow cover distribution and snow melt in cold and arctic environments. Since 1969 a research basin (Sagelva hydrological field) has been in operation close to Jonsvatnet east of Trondheim. Two climate stations and four discharge stations are continuously in operation. Another important area of research in hydrology is the development and application of various forms of hydrological models. Over the last years this has included precipitation-runoff models for inflow prognosis, development of distributed precipitation-runoff models for assessment of changes in land-use and development of hydroinformatics systems used e.g. for large scale catchments analysis and complex model integration.

The department has a growing research activity on issues related to the interaction between the physical environment of rivers with the aquatic ecosystem, commonly referred to as eco-hydraulics or eco-hydrology. Our most important area within this field is the assessment of impacts from river regulations, but over the latest year more general research topics within this area has also been addressed. This research activity is closely linked to the water resources group at SINTEF Energy Research and to several biological research institutions.
2. Research collaboration with business and public sector and research impact
Collaboration with business and public sectors

The group has a close cooperation with various businesses and public sector actors. Members of the group work with consultants and hydropower companies on research projects and as experts on applied projects.

The group is offering assistance for calibration and optimal use of precipitation-runoff models for hydropower operation for several of the largest power companies in Norway (e.g. Lyse Kraft, Elkem, Østfold Energi and TrønderEnergi). We have cooperated with Powel ASA, the leading company for software for power companies, in software development, model documentation, model calibration and quality control.

Recently a project has started in cooperation with Lyse Kraft, The Norwegian Meteorological Institute, STORM Weather forecasting and the company INDEC AS. The purpose is to create and run a test system for studying the quality of meteorological forecasts, and its effects on errors in hydrological models for hydropower systems.

Similar arrangements exist with directorates like the Norwegian water resources and energy directorate (NVE) and the directorate for nature management (DN). During the “power crisis” last year Prof. Killingtveit worked at NVE and developed a system for monitoring and documentation of energy inflow and energy storage in the hydropower system in Norway and Sweden. Prof. Killingtveit is also working with NVE on EUs Water Directive. Assoc. Prof. Alfredsen is currently working on a DN resource group on fish ladders and salmon migration.

A computer model for simulation of hydropower and reservoir systems (nMAG2000) has been selected by the consultant company Norconsult for use in power system planning in Norway and internationally. The same model is also used by another large consulting group (Statkraft-Grøner) and by several Norwegian hydropower companies. In Malawi, Norconsult have been carrying out a large study for “Lake Malawi Level Control” where the optimal regulation of Lake Malawi and Shire river has been studied. A simulation model for the system was developed based on the PINE simulation model development tool which was made as part of a PhD project. This system was also used for modelling in the large HYDRA flood research project, and is now being used for all hydrological forecasting in the Skagerak power company.


Collaboration with research institutions

In the field of eco-hydraulics the group has a close cooperation with researchers at SINTEF Energy Research, in most cases operating as one unit. Work in this field will always also include researchers from the areas of ecology and biology within the Norwegian Institute for Nature Research and the laboratory for freshwater and inland fisheries at the University of Oslo, Department of Zoology at NTNU or international partners.

The group has research cooperation with SINTEF and NVE on the EU Water Directive and its effect in Norwegian water management and the hydropower system. Cooperation takes place with NVE, NINA and SINTEF in the study of the Orkla River as a Norwegian contribution to the project: ”European module on river channel design and environmental protection in Europe”. We have also research cooperation with SINTEF and NVE on several projects in Arctic Hydrology in Svalbard. We are cooperating with NINA in a planned project about Climate Change and its effect on ecosystems in selected catchments in Norway and with NGU in groundwater hydrology and Geochemistry in Norway and on Svalbard.

The group is participating in an international research programme (NFR and EU sponsored) on stability and breaching of embankment dams in cooperation with NGI, SINTEF, EBL Kompetanse, NVE, Wallingford Hydraulics (UK), and various international consultants and power companies in Norway, Sweden, Canada and France.

The group is deeply involved in the research carried out at Hydro Lab Pvt. Ltd. at Institute of Engineering, Tribhuvan University in Nepal. Prof. Støle is serving as permanent scientific advisor and assistant prof. Robertsen was a guest researcher there during his sabbatical in 2001/2002. This activity involves assistance in developing a hydraulics research laboratory for both basic and contract research, and direct participation in the ongoing research projects by the group members. Hydropower development in sediment loaded rivers, sediment and flow gauging and efficiency measurements of turbines are focal research areas of Hydro Lab both in Nepal and Bhutan.
Patents

A system for reducing head losses in unlined power tunnels was patented by two former PhD candidates (T. Jacobsen and L. Jenssen). Two patented systems for removal of deposited sediments in settling basins and small reservoirs were invented by Professor Støle when he was a PhD candidate at the department.

Role of the group related to creating and establishing of new industrial activites

The company Sediment Systems AS was established by Haakon Støle in 1994. The company supplies consulting services as well as the S4 sediment flushing system and the SMOOTH sediment monitoring systems. The patented S4 system is installed at three power plants in Nepal and is used in the design of several plants which has not been built yet. The company G-Flow was established to commercialize the technology for reducing head loss in unlined tunnels patented by Jacobsen and Jenssen. Tom Jacobsen, a former PhD candidate who worked on sediment transport, has started GTO-Sediment AS which provides sediment handling technology (also patented) and equipment to the hydropower- and offshore industry. As a spin-off from research and software development during the 1980’s and 90’s the company Hydroinformatikk AS was founded in 2000. Today the company serves power analysis companies and several hydropower companies in Norway, Sweden and Iceland with analytical tools and forecasting models covering the whole Nordic power market and the hydropower systems in Germany, Austria, Switzerland and France.


The role of the group in dissemination of own research

The group publishes results and findings through international and national publications, participation in conferences and working groups and by participation in applied projects with industry and public sector. Examples are participation in the hydropower businesses technical meetings and meetings for personnel responsible for dams and dam safety. Members of the group participate in hearings and the development of design manuals and design procedures related to hydropower development and dam safety. The group is also responsible for the course (EVU course Damsikkerhet II) that qualifies personnel to be responsible for dam safety issues. This course runs one time each year. Similar courses have been developed for hydropower hydrology and flood zone hydraulics. During 2001 – 2003 a number of courses on power market and hydropower operation were run in Norway and Sweden by Montel. A significant part of this course was hydrology and these lectures were provided from our research group. The group also is represented in specialist groups working as advisors to industry and government.

Members of the research group have been involved in editing and authoring a 17 volume book series: Hydropower Development. The work has been a cooperative task between several Norwegian institutions involved in hydropower development covering researchers, consultants and managers. This comprehensive multidisciplinary documentation of hydropower development is published by the department and demonstrates Norway’s unique competence and role as a leading country in environmental friendly hydropower technology.


  1. Strategy, organization and national cooperation

The staff and budget for the hydraulics laboratory is at present below the level of subsistence. Four permanent staff members are required (1 lab-technician, 1 lab-engineer and 2 researchers). Investments of approximately 5 mill. NOK over a period of 3-5 years in equipment and other facilities are required in order to bring the laboratory up to the level required to be the best in the areas we do specialize. The permanent scientific staff, PhD and post.doc fellows will together with the permanent laboratory staff form a research group with 8 to 10 members. This is adequate in order to maintain a hydraulic laboratory of international standards in Norway. We do intend to continue to work closely together with Hydro Lab in Nepal with respect to applied and contract research internationally.

The strategy for further research on numerical modelling of sediment transport is to increase the number of researchers in the group. This will be done by recruiting and funding new PhD students and post-doc researchers. In cold climate hydrology we need to improve equipment for rapid ground truth measurements in catchments. The activity within eco-hydraulics have been increasing over the latest years, and together with partners at SINTEF Energy research we want to further expand and develop this activity. Some important strategies and goals for the future is to further increase the international participation in projects, increase the rate of publishing and transfer of results to practitioners in the field and find funding for more PhD and post doc level researchers.

Within eco-hydraulics research the group collaborates with researchers at the department of Zoology. In the Pangani-project in Tanzania (1997-2001, 2002- ) there were close cooperation between our group and researchers within Geography, Botany and Economy at NTNU, and similar research groups at the University of Dar es Salaam. The research was coordinated from the Centre for Environment and Development at NTNU in the first years, now the Arena for Development Research. Within sediment engineering the group collaborates with the Department of Energy and Process Engineering on sediment measurements, efficiency measurements and wear measurement of hydraulic machinery. Through the NUFU project between NTNU and Institute of Engineering in Nepal, the department has a close cooperation with the Department of Civil engineering and transport and Faculty of architecture. Prof. Støle is member of the advisory council of the Arena for Development Research which is located at the Department of Geography (SVT faculty).

The group has a close relation the SINTEF Energy Research on research in eco-hydraulics and also cooperation with SINTEF Energy Research on hydrology.


  1. International collaboration and other international relations

Cooperation with international research partners extends the scope and the possibilities in the research projects, provides possibilities of exchange of personnel both among the staff and students at the department and provides new input and new solutions to problems. In most areas of research there is a good level of contact with international research institutions. Prof. Støle and assistant prof. Robertsen work with HydroLab at Institute of Engineering, Tribhuvan University in Nepal on sediment engineering, physical modelling and hydraulic design. In the hydropower research there is also a cooperation with the International Centre of Hydropower (ICH). The group has a part in an ongoing cooperation between the university of Dar es Salam and NTNU focused at hydrological effects of land use changes. One PhD student (Paul Chr. Røhr) worked full time on the project and finished in October of 2003. Prof. Killingtveit is the coordinator of the project and responsible for input from NTNU. The project has led to exchange of many Norwegian MSc and one PhD students for work in Tanzania, and from 2004 two Tanzanian PhD students working in Norway in a sandwich model. Prof. Killingtveit was the national project leader for the EU funded project: ”European module on river channel design and environmental protection in Europe”. The result of this project is the development of a teaching module and a book on river design and environmental protection. In the field of CFD there are research cooperation with the University of Cardiff, University of Vienna and University of Karlsruhe. Within eco-hydraulics we have research cooperation with University of New Brunswick, DFO Newfoundland, Cemagref in France and CEH Wallingford in UK.

  1. Recruitment and mobility of researchers

At the time of writing most of the PhD students are recruited internationally. Over the latest years several diploma students from international universities have taken part in the research. Most doctoral students spend time at international institutions during their study.

Several of the PhD students have entered into jobs in businesses (e.g. consultants or power companies). Others have entered into jobs in the public sector, e.g. academic or government. Over the last ten years five has gone to the public sector and six to private sector.


  1. General conditions applying to the research

It is too difficult to get funding for instruments and equipment. There are few openings for investing in modern equipment, and not enough technical assistance for operation and maintaining state-of-the art equipment. Also it is quite difficult to get funding for long-term activities like operation of research catchments (the hydrological field Sagelva).

Increased resources are needed now in order to prevent that the hydraulics laboratory for river and hydropower engineering shall be closed down. This was one of the first laboratories established at NTH in the basement of the main building. If NTNU does not give priority to this, the largest hydropower producing country in Europe (Norway) will not have any laboratory for physical hydraulic modelling of rivers, dams and waterways of hydropower systems. It seems impossible to modernise and equip a national hydraulics laboratory within the framework of the budget of the department.





B. Group level - The water and wastewater engineering group
This group has a very close cooperation with SINTEF Water and wastewater and the research activity is divided in two thematic sub-groups (research groups) even though cooperation between them is close. Each of the two sub-groups includes researchers from IVM (academic staff and PhD-students) as well as from SINTEF Water and wastewater. The two sub-groups are: Water and wastewater treatment (headed by prof. Hallvard Ødegaard and called the Treatment Group below) and Water and wastewater systems (headed by prof. Wolfgang Schilling and called the Systems Group below). The treatment group has around 20 members (depending on number of PhD-students at any time) split with around 50 % on each of the two home institutions while the systems group has around 15 members out of which around 1/3 are employed by NTNU and the rest by SINTEF.

The treatment group was started shortly after the appointment of Hallvard Ødegaard as the first NTH-professor (dosent) in water and wastewater treatment in 1977. SINTEF had already some activity in the area at its Department of Applied Chemistry and in 1980 our department and SINTEF merged their research activity under the leadership of Ødegaard. Several dr.ing.- graduates from our department during the first half of the 80’ties were employed by SINTEF. Even though the water treatment activity of SINTEF has been organized in different organizational units of SINTEF over the years (SINTEF Applied Chemistry, SINTEF NHL, SINTEF Civil and Environmental Engineering and SINTEF Chemistry), the strong tie to our department has always been maintained.

The systems group did not have a similar strong relation to SINTEF until around 5 years ago when especially the joint effort in several EU-projects made it beneficial for the two departments (at SINTEF and NTNU) two merge in a similar fashion as the water treatment group had done many years earlier. Prof. Schilling and adjunct prof. Sægrov have their main positions at NTNU and SINTEF, respectively, and part-time positions at the partner institution.

As SINTEF activities are mainly demand-driven and IVM activities competence-driven the collaboration of colleagues from the two institutions is very fruitful with respect to discussing overarching questions of relevance, quality, etc.


1. Description of research activities
The treatment group

The treatment group is an experimentally oriented research group with most of the projects targeting development of new treatment processes as well as optimization of treatment processes both for drinking water, industrial process water (for instance in aquaculture), municipal and industrial wastewater and sludge treatment. The group was appointed a strong point center by the joint research committee of NTNU and SINTEF for the period 1996 – 2001 (that implied an extra amount of direct research money from the two institutions). The group aims at becoming a Gemini Center at NTNU/SINTEF in 2004.

The particularly strong areas of research are removal of humic substances in drinking water and removal of nutrients in wastewater (phosphate by chemical precipitation and nitrogen by nitrification/denitrification in biofilm processes). In terms of unit processes, the group has strong competence in all the particle separation processes (coagulation, flocculation, flotation, granular media filtration and membrane filtration). Currently the focus activity is membrane filtration, a unit process that probably will revolutionise the water and wastewater treatment sector during the next decades. On the applied research side, the group has put a lot of emphasis on biofilm processes and has developed “the moving bed biofilm process” that is now commercialised by Kaldnes Miljøteknologi AS and become very popular in practice all over the world.

In the area of water hygiene the research has been focused on rapid techniques for detection of bacteria in contaminated water aiming at development of rapid techniques for determining bacterial water quality and disinfection efficiency, and for assessment of bacterial viability.

Disinfection of water and wastewater is another research activity, and the group works both with traditional (ozone, UV) and new (e.g. membrane technology) disinfection processes for removal of microorganisms (virus, bacteria, protozoa) from water.
The systems group

The systems group is focusing on urban hydrology and urban drainage, especially in cold climate, monitoring of urban hydrology processes, drinking water transport and distribution urban water infrastructure management, non-point source water pollution modeling and control, real time control.

The process-oriented subjects, e.g. monitoring and modelling, often are dominated by basic research (PhD), while the infrastructure-oriented activities are more applied projects with intense interaction between the systems group and end users outside of NTNU/SINTEF. The activities in the process-oriented subjects have been on a relatively stable level for many years, i.e. with PhD-research going on at any time and the long-term operation of the urban hydrology field laboratories in Trondheim and Bergen. The infrastructure-oriented subjects, on the other hand, are massive projects that typically involve numerous international research partners and end users. Apart from the topical research in these infrastructure projects the systems group is also coordinating some of the biggest of these projects. Hence, the group is responsible for scientific and administrative management.

Assoc. prof. Thorolfsson initiated the establishment of the Risvollan urban hydrological field laboratory Risvollan (20 ha) in Trondheim, Norway and the group has since 1986 operated the Risvollan measuring station, with some support from Trondheim municipality and NVE. This long term activity has resulted in the basis for the ongoing comprehensive research on urban runoff in cold climate. A similar field was established at Sandsli urban research catchments (10.2 ha) in Bergen in 1981.

The experimental data and research into processes in urban areas under cold climate conditions are rare and in big demand in the world as recognised by UNESCO (“Urban Drainage in Cold Climates”, IHP TDH No. 40, Vol.II, Paris 2000). The database at Risvollan may be one of the longest series on such data in the world with that high resolution and quality. The UNESCO publication, to which researchers from Canada, Sweden, Russia, Norway and USA have contributed, reveals the lack of reliable data which are crucial for the real breakthrough in both modelling and operational management. The current research into snow-dominated processes continues.
2. Research collaboration with business and public sector and research impact
Collaboration with business and public sector

The treatment group has, in close collaboration with SINTEF, sought contracts with companies in which the group plays an important part of the R&D activity of these companies. The best example of this is the cooperation with Kaldnes Miljøteknologi AS. More than 70 international papers based on this cooperation have been published.

Similar arrangements (even though not so close) have been created with Optiroc A/S, Kemira Oy and others. The group has made long term research contracts with companies like these in which financing of applied as well as basic research (i.e financing of PhD-students) has been included.

The group initiated research (1985) and development of techniques for rapid detection of bacteria in water, which was later developed by a company (Colifast) into a commercial instrument.

The dominating collaboration aspect in the systems group is its heavy involvement in European R&D projects in programmes such as COST, EUREKA and especially the 5th Framework Programme. Through these projects the number of international partners (end users) with regular scientific contacts is in the order of 30 out of which the 5 largest cities in Norway.

Both the systems group and the treatment group have had short term contracts with several municipalities and the systems group has gone into long-term R&D collaboration agreements with Trondheim, Bergen regarding operation of urban hydrological field stations (Risvollan and Sandsli).


Collaboration with research institutions

During the last 5 years, several of the senior staff had formal sabbaticals and cooperation have been established with the visiting institutions:



  • Department of Environmental Engineering Hokkaido University (host prof. Y. Watanabe), Japan (H.Ødegaard)

  • CSIRO Molecular Science (host dr. D. Dixon), Melbourne, Australia (H. Ødegaard)

  • UNESCO Membrane Research Centre, University of New South Wales (host prof A.Fane), Sydney, Australia (T. Leiknes)

  • INSA de Lyon (host prof. B. Chocat), Lyon, France (W. Schilling)

  • U Ferrara (host prof. V. diFredirico), Italy, (S. Sægrov)

  • University of Seattle (host dr. D. B. Booth/D. Lettenmaier), USA (S. Thorolfssson)

  • CIRSEE, Suez-Lyonnaise des Eaux (host dr. L. Kiene), Le Pecq, France (L. Fiksdal)

The treatment group is cooperating with EAWAG - Swiss Federal Institute for Environmental Science and Technology (connected to ETH, Zürich, Zwitzerland) on a American Water Works Association funded membrane project. In the membrane area cooperation has also taken place with University of Minnesota (prof. M.Semmens) and University of Sapporo, Japan (prof. Y. Wataanabe). The group has collaborated with several institutions on a STREP application under the EU 6’the Framework Program (i.e. Instituto de Biologia Experimental e Tecnológica, Lappeenranta University of Technology, Imperial College, London, INSA-Toulouse, Delft University of Technology, Bourgas University, Bulgaria, EAWAG - Swiss Federal Institute for Environmental Science and Technology,  University of Minnesota, USA, University of Natal, South Africa, SINTEF Applied Chemistry, Department of Water and Wastewater,  Membrane Extraction Technology Ltd.).

The systems group collaborates through the EU-projects with a number of research institutions in Europe (i.e. Water Research Centre WRc, UK, LNEC, Portugal, INSA de Lyon, France, TU Dresden, Germany, TU Brno, Czech Republic, U Ferrara/U Bologna/U Palermo, Italy) with whom the systems group literally has daily contacts as well as mutual personal collaboration visits.

The department has (sometimes in collaboration with SINTEF) hosted several visiting researchers, graduates (> 10 in last 5 years) as well as post-graduates (> 10 in last 5 years) and post-docs (> 10 in last 5 years). Many of these have been Marie Curie scholars and quite a few financed their stage with their own funds. International recruitment to these visiting researchers has been no problem due to international projects (EU, COST, EUREKA) and personal networks


Patents and contracts and important projects with business and public sector over the last 5 years

A significant patent is the one on the “moving bed biofilm process” owned by Kaldnes Miljøteknologi with prof. H. Ødegaard as the inventor.

  • Risk management (initiator, leading, new in 2003)


Role of the group related to creating and establishing of new industrial activites

The best example of this is the cooperation that the treatment group has with Kaldnes Miljøteknologi AS. This company was formed on the basis of a process invention made in the group and the group has taken active part in the company’s R&D all the time even under various owners (Norwegian, British, Swedish) of the company. It is the policy of the group to establish close links with the companies with which we cooperate and to take part in their R&D planning

An example in the systems group is the commercialization activities in the finishing stage of the CARE-W project. Although still being discussed the most likely outcome will be an internationally owned company marketing the CARE-W technology, starting to operate early 2004. The group is planning a commercialization of the CARE-S technology based on that experience starting 2005.
The role of the group in dissemination of own research

The treatment group has taken actively part through own research in the areas of humics substance removal, development of biofilm processes and development of membrane processes through numerous international publications, organizing of international conferences in Trondheim (Removal of humic substances, Trondheim, 1999, Japanese/Norwegian workshop on membrane filtration, 2002, European Membrane Society 20th Summer School, 2003) and taking part in several program committees on these subjects.

The systems group is leading in Europe in IT-tool development for urban water infrastructure rehabilitation (coordination of CARE projects) and leading in cold climate urban hydrology (e.g. participation in UNESCO project on Urban Drainage in Cold Climate). All EU-funded projects involve dissemination work packages and consequently, there are numerous national and international workshops, seminars and conferences run in the context of the respective project (e.g. CARE-W conferences in Dresden/GER and Bath/UK, for complete overview see http://citynet.unife.it/)
3. Strategy, organization and national cooperation
In the treatment group the strategy is to continue the close cooperation with SINTEF water and wastewater in applied research aiming at close cooperation with Norwegian and international businesses that are commercialising products and processes where the group has particular competence. Currently the group is strategically focusing on membrane filtration and a post doc – as well as two PhD-scholarships are allocated to this area for next year. Already one PhD (finished in 2004), one post-doc (2003) and one visiting post graduate (2002-2003) has been allocated to this area of research. Five M.Sc. thesis projects have been completed within the topic. The department has also taken the coordinating function in a STREP-application under the EU 6’th Framework Program focusing on the development of hybrid membrane bioreactor treatment processes for wastewater reuse. This strategy is the result of discussions in the joint group of our department and SINTEF as well as with discussions with the industry with which we cooperate. We have gone into cooperative agreement with several membrane businesses (e.g. Zenon Inc, Canada, Hitachi Plant Inc, Japan, Hitachi Metal Inc, Japan, Asahi Chemicals Inc, Japan, Polymem, France, EIDOS, Czech Republic, Membrana GmbH, Germany)

In the systems group it is the strategy to continue taking advantage of special Norwegian conditions and concentrate on cold climate aspects and infrastructure management (large assets per capita!). The group aims at expanding in scope, e.g. include drinking water aspects in cold climate research, move from pipe network management to system management (incl. pumps, tanks, armatures, etc.). The group also want to expand international collaboration (EU-FP6, EU-COST, Norwegian Church Aid, China) and pursue integrative research on climate change effects on urban water and wastewater management. Building on the group’s project management experience it is planned to submit a proposal for an integrated project in the 6th Framework Programme of the European Commission. None of the three senior staff members is below 50 years, and it is of strategic importance to engage more junior staff, either in full-time or part-time positions.

The water and wastewater engineering group did take part in a strategic university project on management of the built infrastructure, concluded 2001, where 4 NTNU departments involved. In parallel a Strategic Institute Programme with SINTEF and NBI was carried out. This area of research is pointed out as one of the strategic areas for the faculty and work currently being initiated aiming at establishing a greater research program in Norway on management of built infrastructure.

In the membrane filtration research area cooperation is established with Department of chemical engineering (prof. May Britt Hägg) at Faculty of Natural Science and Technology.

Research in the water and wastewater area requires interaction with professionals from many disciplines. Therefore group members have different disciplinary backgrounds (engineering, biology, microbiology, chemistry etc). As already explained, most of the work is fully integrated in NTNU-SINTEF groups, i.e. NTNU staff serve as scientific advisers and SINTEF senior staff has part-time teaching position at NTNU.
4. International collaboration and other international relations
Both of the groups (Treatment group as well as Systems group) are very internationally oriented. Cooperation with other university groups comes often as a consequence of sabbatical visits (e.g. Hokkaido University, University of New South Wales, INSA de Lyon etc). The treatment group as not been as active in EU-projects as the systems group that has oriented a considerable part of the research towards EU-projects.

The most important aspect of the international R&D collaboration in the systems group (e.g. CARE, RISURSIM, TILDE projects) is the fact that the quality and scope of the developed tools are far beyond what could have been achieved in local or national projects (e.g. the whole NFR drinking water program has 5 mio/yr, CARE-W alone has 8 mio/yr). Through our international projects we attract guest researchers that enjoy very favourable working conditions at IVM.



The treatment group has also taken the coordinating function in a STREP-application under the EU 6’th framework program focusing on the development of hybrid membrane bioreactor treatment processes for wastewater reuse. In the hygiene field the department has been involved in one EU research application on monitoring pollution for soil-groundwater protection and rehabilitation MONIPOL (October 2003) Proposal for a Co-ordination Action.

  1. Recruitment and mobility of researchers

Most of the doctoral students spend a period abroad, and recruitment is formally open to all applicants worldwide. The department group has recruited a number of researchers internationally and during the last 5 years we have had researchers (Post-graduates, Phd-students, post-docs and visiting researchers) from China, Thailand, Russia, Italy, Czech Republic, Germany, Sweden, Bulgaria, Switzerland).

Several of the PhD-students have entered into SINTEF or into research oriented jobs in businesses (e.g. Aquateam AS, Kaldnes miljøteknologi AS, Optirock AS, Norsk Hydro ASA) and some have gone into consulting engineering companies. It is estimated that about 70 % of the PhD-candidates during the last 10 years has gone into the business sector.
6. General conditions applying to the research
In general it can be said that the conditions are relatively good in terms of physical facilities and office space. Compared to other countries we also believe that PhD-funding through scholarships is quite good, even though we would like too see a higher number of scholarships being offered. We also believe that it would be very beneficial with an increased funding of post doc’s as it is a challenge to offer the new PhD’s interesting research work after they have finished their degree. The greatest challenge seems to be to recruit juniors that are “thrilled” by research. Little incentives for juniors to take up a research post (lost salary can hardly be compensated by high income later, no added status in Norway by having a PhD).
