Abstract


The Urban growth has proven give a significant effect on the hydrological watershed function. Information. Information about the impact on the water resource in such watershed could be spatially quantified using GIS tool. The response of Cicatih watershed in West Java to various scenarios was determined using SCS method. In the scenarios, the effect of an increase in settlement cover to surface runoff and water storage was examined. The results indicate that surface runoff increase to 79% and water storage decrease to 31% due to settlement expansion.

Keywords


surface runoff; SCS method; actual water storage; spatial distribution
