Hydrological characteristics using the SWAT model on several agricultural systems in the Maros karst area

Abstract In the region of karst, there are valley areas that used by community as agricultural land. However, drought phenomena often occur in this area, so it is necessary to know presence water support processes. The aim research predict flow rates several systems using Soil and Water Assessment Tools (SWAT). SWAT was chosen because can simulate model with easy-to-obtain data. Required data such Digital Elevation Model (DEM), soil type, land cover form a Hydrology Unit Response (HRU). Enhanced climate input run Run. scenario done Land Use Split HRU Definition menu. results showed forest vegetation defined FRSE FRST stored better than AGRR RICE lands. different for underground flow, store better. show decrease value surface runoff 15.3% an increase lateral 26% from existing condition. continued but not significant at 4.2%.
