Planet Earth’s atmospheric-hydrospheric-lithospheric interactions create situ-ations favorable for FLOODS

  • Planet Earth’s atmospheric-hydrospheric-lithospheric interactions create situ-ations favorable for FLOODS



























At least 1,000 feared dead

























  • Ninety-five dead

  • Over 2 million homeless.

  • Half a million evacuees are living in relief camps with disease prone conditions

  • Damaging landslides hindered relief operations















A risk assessment involves the probabilistic integration of:

  • A risk assessment involves the probabilistic integration of:

  • The hazard (e.g., floods) and their potential disaster agents (inundation, erosion, etc) that are directly related to the location of the community and what happens in the regional water cycle.



The location of each element of the exposure in relation to the physical demands of the hazard (i.e., inundation, etc.)

  • The location of each element of the exposure in relation to the physical demands of the hazard (i.e., inundation, etc.)



The exposure (e.g., people, and elements of the community’s built environment), represents the potential loss when the natural hazard occurs.

  • The exposure (e.g., people, and elements of the community’s built environment), represents the potential loss when the natural hazard occurs.



The vulnerability (or fragility) of each element comprising the exposure when subjected to the potential disaster agents.

  • The vulnerability (or fragility) of each element comprising the exposure when subjected to the potential disaster agents.













Urban development or industrial development in areas that were formerly wetlands.

  • Urban development or industrial development in areas that were formerly wetlands.

  • Locating buildings and infrastructure in a river floodplain.



Actions that increase or decrease river gradients (deforestation, dams, etc).

  • Actions that increase or decrease river gradients (deforestation, dams, etc).

  • Actions that change the runoff rate or pattern (e.g., the city’s concrete footprint)



A flash flood.

  • A flash flood.

  • Ice jams/ice dams on the river

  • Rapid melt of snow and ice

  • Extreme or prolonged precipitation caused by stalled low-pressure weather systems.





Physical characteristics of the regional water cycle and drainage system.

  • Physical characteristics of the regional water cycle and drainage system.

  • Physical characteristics of each river system, its tributaries, and its floodplains.



Physical characteristics of catchment basins, reservoirs, and wetlands in the region.

  • Physical characteristics of catchment basins, reservoirs, and wetlands in the region.

  • Physical characteristics of dikes, levees, and dams controlling water discharge and flooding potential in the region.



The hazardous materials and other elements located in the floodplain.

  • The hazardous materials and other elements located in the floodplain.









When it does happen, the functions of the community’s buildings and infrastructure can be LOST for long periods.

  • When it does happen, the functions of the community’s buildings and infrastructure can be LOST for long periods.



The community is UN-PREPARED for what will likely happen, not to mention the low-probability of occurrence—high-probability of adverse consequences event.

  • The community is UN-PREPARED for what will likely happen, not to mention the low-probability of occurrence—high-probability of adverse consequences event.



The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.

  • The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.



The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.

  • The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.



The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either the current experience or the cumulative prior experiences.
