A Conceptual Stream-Aquıfer Model İncorporatıng Surface Water-Ground Water İnteractıons

Ground water is an important part of the hydrological system and it has a strategic place in protecting and developing water resources being depleted nowadays. As a natural resource, ground water plays an important role in water quality and water supply. Regionally assessing the distribution of water resources and environmental pollution is inevitable for determining water supply and water quality. Therefore, the physical mechanism of the ground water should be determined by developing detailed hydrological and contaminant transport models. While many studies cover ground water as a single system and therefore investigate pure ground water hydraulics and hydrology, studies related to surface water-ground water interactions and the behavior of ground water by conducting a sensitivity analysis under different scenarios are exiguous in the literature. Generally, surface water and ground water are examined separately in the literature; however, in this study they are considered as a unique system and the simulations are done accordingly. In this study, a conceptual stream-aquifer model is developed by using VISUAL MODFLOW computer program which is capable for simulations of ground water flow and ground water contaminant transport. The hydrological behavior of the conceptual stream-aquifer region is observed and the effect of surface water-ground water interactions on the hydrological behavior of stream-aquifer region is investigated. Ground water level fluctuations and the flux between stream and aquifer are obtained with the hydrological model of the conceptual stream–aquifer system by conducting sensitivity analyses for different stream and aquifer parameters and flow paths. In addition, the concentration distributions in aquifer formation for different flow paths are obtained by using the stream-aquifer contaminant transport model. By using conceptual stream-aquifer model, the flow rate between surface water and ground water for the stream-aquifer system are studied and the effect of surface water-ground water interactions on mass flux between stream and aquifer are investigated.
