Abstract:
One of the aspects of the dam break Emergency Action Plans (EAP) is to describe the anticipated darn failure scenarios and the corresponding arrival times of dam break floods at different locations of interest downstream of a dam alongwith the description of areas that could be inundated. This requires the performance of a darn break analysis as the basis for delineation of possible innundation areas. This paper presents the general principles behind the mathematical models used for dam break analysis, and identifies various available models for dam break analysis. Also a brief description of the well known U.S. National Weather Services DAMBRK model, and its application for the flood wave simulation of the Machhu dam-II failure is presented.
