Abstract
Climate change has significant impact on hydrology and water quality. A simple Long Term Hydrologic Impact Assessment tool has been developed using model builder in ArcGIS 9.3 to simulate hydrology and water quality. The model developed to read precipitation data from netCDF format to simulate runoff. The tool box developed to simulate hydrology based on the widely used USDA Curve Number method and water quality using EMC (event mean concentration) of pollutant. The model in GIS allows easier management of input and output data and allows critical spatial and visual interpretation. The model developed for Wisconsin State, where the precipitation data (estimated) was available for 200 years (1900 to 2100). The tool box was found to be very useful and user friendly
