Distributed watershed models require the support of Water is one of the most important natural resources sup- geographic information system (GIS), which is a computer- porting all forms of life on earth and the sustainable use and ized data base management system for capture, storage, re- conservation of this resource has to be planned on watershed trieval, analysis and display of spatially referenced data.
