Abstract


Cimanuk Watershed is a priority catchment in West Java Province. The objective of study is to analyze various land use scenarios to improve base flow and lateral flow. The analysis use SWAT Hydrology model. The study showed that model has a good performance in predicting flow discharge produced NSE 0.56 (satisfactorily) and R2 0.70. There are four scenarios to be analyzed. The best base flow and lateral flow analyses is from the first scenario with soil and water conservation techniques. The scenario resulted the river regime coefficient by 78 (moderat), reduce direct runoff by 40.76% and increase lateral by 536.95 mm.

 

Keywords: Base flow, landuse, lateral flow, soil and water conservation techniques, SWAT model
