• Vegetation data: UMD 1km Global Land Cover dataset - year 1994 • Soil data: Global Soil Data Task 2000 - Global Soil data product (IGBP-DIS) 0.5 minute resolution • Elevation data: Shuttle Radar Topography Mission 3-arc second (SRTM- 90M) compiled by Consortium for Spatial Information of the Consultative Group for International Agricultural Research (CGIAR-CSI) • River network: The Digital Chart of the World (DCW), which is the Environmental Systems Research Institute, Inc. (ESRI)’s product originally developed for the US Defense Mapping Agency (DMA) using DMA data. The dataset used was the DCW 1993 version, at 1:1,000,000 scale • Watershed boundaries: River basin boundaries are based on the EROS Data Center HYDRO1k basin boundaries developed at the U.S. Geological Survey (http://edcdaac.usgs.gov/gtopo30/hydro/) All data sets were re-calculated by GIS technique to 5 km resolution for operational model resolution. Baseline hydrological condition: Model calibration The baseline hydrological regime for further analysis was simulated by VIC hydrological model. This is also part of model calibration process, of which the result from the simulation was compared against the observed data during the 1980s. The simulation was performed to calculate tributaries run-off at various key locations where observation stations are located and model calibration was performed by using the observed data from these stations. The calibrated hydrological simulation result is shown in the Appendix 2: Hydrology Calibrating Result. The result shows that VIC model is able to simulate total discharge reasonable well in most of the sub-basis under this study. However, the model still has limitation in simulating the month-to-month discharge, this may due to the model limitation in handling the soil property, particularly the soil moisture. In addition, the model still has limitation in handling back water effect from the main stream into the tributary. The locations selected for the baseline simulation and calibration are as shown in the illustration and table below: <strong>Final</strong> technical report – AIACC AS07 44
