WebHydrologic Engineering Center’s River Analysis System (HEC-RAS) software is used for the dam break analysis. Results obtained from the study indicated that overtopping failure yields the highest peak breach flow of 202,099 m3/s, compared to piping failure’s highest peak discharge of 201,126 m3/s. 1. Introduction WebThe HEC-1 Program will develop flood hydrographs and breach hydrographs and route the downstream flows through stream cross sections, roads and other dams. The "smpdbk" (Simple Dam-Break) program is a shortcut version …
