Breach discharge hydrograph

Webdischarge and volume of storage are directly related. Routing, breach—This procedure derives the hydrograph at downstream locations from the hydrograph generated by a breach or failure of a dam. This routing may include hydrographs resulting from precipitation in addition to the breach hydrograph. Throughout this document, when a … WebThe two primary tasks in the analysis of a potential dam failure are the prediction of the reservoir outflow hydrograph and the routing of that hydrograph through the downstream valley to determine dam failure consequences. When populations at risk are located close to a dam, it is important to accurately predict the breach outflow hydrograph and its timing …
