Hi there,
Is there anybody with some experience on DAM BREACH modeling? Is it possible to do from HEC-RAS? I am trying to see the flood hydrograph of a mountain glacial lake for lake burst flood hazard assessment. Your help if any is appreciable. Thanks.
You can do do dam breach modeling in RAS.
However, RAS will not calculate the size of the breach opening or the breaching time. You will have to input the final breach dimensions (width, depth, etc.) and the breach formation time. It is entered from the Inline Structure menu (Geometric Data window).
