Abstrak: Influence of hydrological response of surface runoff which occurred in Walanae Watershed can be known through large or small values of rainfall along river basin and the biophysical characteristics of river basin. When rainfall is small or moderate, surface runoff only occurred in region that impermeable and saturated in a river flow area / or direct falls on surface of the water. Morphometric observed in the riverbank of Walanae is the pattern river network, river order, flow drainage density, the ratio of river branching, and slope degree. Conditions of Walanae basin can be represented by calculating the coefficient of riverflow regim, which is the ratio between maximum and minimum discharges. The value of the river regim coefficients that obtained for each year respectively are; 2007 = 229; 2008 = 276; 2009 = 245; and 2010 = 340. These values indicate that the river basin Walanae has experienced degradation or malfunction of upstream watersheds, because the value of the coefficient of regim river >120 and tend to increase each year. Estimation analysis of watershed surface runoff of Walanae using method of Soil Conservation Service (SCS), is obtained by calculating the curve number of the river basin. Based on the analysis results, surface runoff capability of watershed Walanae in 2010 is higher (154.29 m3/s) than in 2005 (13.32 m3/s). This large runoff values is caused by current curve number of this large watershed. Larger value of curve number resulting larger value of surface runoff.

Judul: Analisis Debit Aliran Sungai Menggunakan Model SWAT di Sub DAS Ciasem Kabupaten Subang Jawa Barat
Abstrak: Increasing developed area and decreasing forest area lead to increase runoff coefficient that further to increase the stream discharge during rainy season and draught in dry season. The hydrological model can be applied to understand that phenomena. One of them is SWAT model. Application SWAT model in this research is focused only in rainfall transformation into discharge. Research is conducted in Ciasem Sub Watershed. The aim of this research is to know the dinamics of land use change and stream discharge in Ciasem Sub Watershed, also to know the effectiveness of SWAT Model for analyzing stream discharge by using available data in Ciasem Sub Watershed. The change of land use at 2003, 2006, and 2009 particularly happened on paddy field which was changed into a mixed agricultural dryland area of about 3253,8 ha, decreased runoff coefficient. Discharge estimation using SWAT model with measured rainfall at Curugagung Rain Station as input did not fit succesfully to measured discharge at Ciasem Sub Watershed outlet. Discharge estimation using SWAT model with simulated rainfall as input results better fitting to measured discharge at Ciasem Sub Watershed outlet with the value of R² > 0,51 and NS > 0,74. The result of the simulation showed that land use change of paddy filed to mixed agricultural dryland decreased runoff coefficient from 0,21 to 0,12 and also monthly maximum runoff discharge from 117,55 m3/s to 79,68 m3/s.
