N2 - Dam construction holds a major disaster risk in when the dam is failure. The occurrence of dam breach can make water reservoir in the dam flow to the downstream at high speed, so it can cause infrastructure damage and the worst is, victim. This study analyses the extent of flooding in the resulting dam break with piping failure mode. The simulation was conducted using HEC-RAS 5.07, with input data consist of Digital Elevation Model (DEM), precipitation data, and dam's technical specifications. The research object is Way Sekampung Dam. The result of simulation show that after dam breach water flowing to the downstream with depth is 48,6 m and flood innundation area in Pringsewu District is 43.17 km2.
