Dam Break and Flooding

Flood extents modeling is typically carried out to determine impacts of a dam break scenario.

Challenges with Dam Break and Flooding

Flood extents modeling is typically carried out to determine impacts of a dam break scenario. Often operators also need to determine the significance of their dam releases in relation to impacts from natural flood events.

EEMS Capabilities

EEMS allows operators and regulators to build 3D models of river systems and flood plains downstream of their dam and accurately model peak flood levels and time of travel, inundation periods and develop mitigation schemes. A wide a range of 2D, 3D and statistical analysis can be generated from the model output to better illustrate and interpret the results.
