Based on Proposal #9 of TMPEGS-Indonesia Year-3 (Y-3) Work Plan, the target in this period was the completion of the three main input components for SWAT analysis: Land Use, Soil and Slope Definition (WBS-300), and maintenance of ArcGIS 9.1 software license. These targets were almost completed except updated of ArcGIS 9.1 license which failed to be accomplished. Fortunately, the recent availability of open source package MapWindows-SWAT (MW-SWAT ver. 44SR), provided freely from www.waterbase.org by United Nations University (UNU), allowed the chance to complete early than expected all SWAT processing chain. Though it only used a low resolution global input data. SWAT-Indonesia now has the "advantage" to proceed with two options: Arc-SWAT or MW-SWAT. Accordingly, the scenario has been adapted to two-step approach: (1) a "quick yield" effort to complete SWAT chain process within Year-3 using MW-SWAT, and (2) an improved SWAT re-process in Year-4, to fine tuning the existing result with local input data (WBS-300) by applying MW-SWAT or Arc-SWAT option.
