随着人口的增长和经济的发展，自然资源利用率的提高，对流域造成了严重的破坏。洪水、滑坡和干旱等自然灾害的影响变得更加频繁。西沙丹流域是印度尼西亚108个优先流域之一。SWAT是一种多功能模型，可用于整合多种环境过程，支持更有效的流域管理和更明智的决策。本研究的目的是探讨适用性的SWAT模型模拟山区集水区，重点是西沙丹集水区在西爪哇省，印度尼西亚。SWAT模型的模拟时间为2005 - 2010年，而2009年使用的是土地利用信息。序贯不确定度拟合方法。本研究采用SUFI-2（SUFI-2）和联合收割机，结合人工标定，对一个小型径流进行了标定。2007年进行了定标，2009年进行了验证，定标的R2和Nash Sutchliffe效率分别为0.71和0.72，验证的R2和Nash Sutchliffe效率分别为0.708和0.7。模拟的月平均地表径流量为27.7 mm，月平均总产水量为2718.4 mm。研究表明，SWAT模型可以作为一个潜在的监测工具，特别是在西沙丹集水区或在热带地区的流域。该模型可用于其他目的，特别是在流域管理。
Increasing of natural resources utilization as a result of population growth and economic development has caused severe damage on the watershed. The impacts of natural disasters such as floods, landslides and droughts become more frequent. Cisadane Catchment Area is one of 108 priority watershed in Indonesia. SWAT is currently applied world wide and considered as a versatile model that can be used to integrate multiple environmental processes, which support more effective watershed management and the development of better informed policy decision. The objective of this study is to examine the applicability of SWAT model for modeling mountainous catchments, focusing on Cisadane catchment Area in west Java Province, Indonesia. The SWAT model simulation was done for the periods of 2005 – 2010 while it used landuse information in 2009. Methods of Sequential Uncertainty Fitting ver. 2 (SUFI2) and combine with manual calibration were used in this study to calibrate a rainfall-runoff. The Calibration is done on 2007 and the validation on 2009, the R 2 and Nash Sutchliffe Efficiency (NSE) of the calibration were 0.71 and 0.72 respectively and the validation are 0.708 and 0.7 respectively. The monthly average of surface runoff and total water yield from the simulation were 27.7 mm and 2718.4 mm respectively. This study showed SWAT model can be a potential monitoring tool especially for watersheds in Cisadane Catchment Area or in the tropical regions. The model can be used for another purpose, especially in watershed management.
