Abstract
For this project, HEC-RAS was used to create an inundation map for the failure of the Charles Lee Tilden Dam in Berkeley, California. A two-dimensional HEC-RAS model was created to simulate the Lake Anza Reservoir, C.L. Tilden Dam, and surrounding topography. HEC-RAS used the Shallow Water Equations to calculate hydraulic characteristics along the most likely path of dam breach flow. The inundation map, which shows the areas which would be adversely affected by the breach of the dam, was created using the maximum depth of water at each point along the dam breach flow’s path. This method can effectively predict the areas which will be inundated by water released by a dam failure and allows evacuation personnel to make informed decisions about which populated areas to evacuate in the case of such an emergency.
