Abstract

Flood always occurs in almost all cities in Indonesia. Likewise in sub DAS Keramasan. Keramasan river in administrative arca’s Palembang pronc to flooding. The natural faetors take cfifcct such as high rainfall intensity, low topographic, whcrcas non natural faetors such as many development and rubbish around the river. The purpose of this study is to mapping llood’s arca in sub DAS Keramasan and design dimension of shortcut to control the flood. Data to this study is secondary data from relevant instances, that is rainfall, topographic map, and land use in sub DAS Keramasan. Analysis data use to hydrology analysis, such as design rainfall and debit inflow and the hydraulic analysis with HECRAS 4.1.0 to find out capacity of river. The rcsult of debit inflow with HSS Nakayasu show that Q,0=96.12 m3/s dan Q25=l 02.01 m3/s. Running HECRAS show that debit inflow biggcr than capacity Keramasan river. The solution to accomplish overflow is design shortcut. Dimension shortcut is bottom width (B) = 15 m, shortcut elevation (H) = 2.8535m, and water surface elevation (h) = 2.195m.
