Design Support System for Prioritization and Watershed Management

A Decision Support System (DSS) has been developed in Visual Basic, net (VB.net) environment for the prioritization and development of integrated watershed management plan for Dikrong river basin of Arunachal Pradesh, India using morphological parameters. Basic watershed parameters like perimeter, maximum length, stream length of each order, numbers of stream of each order values were used as inputs to the DSS. The sub-watersheds were classified into the five scales of priority i.e. very high, high, medium, low and very low using the DSS. The DSS for integrated watershed management plan was also developed by using land use, soil type and slope informations of the sub-watershed area. It can also suggest suitable conservation structures for a given set of soil type, land use, slope and catchment area. The developed DSS can help the end users for watershed prioritization and to suggest various watershed management practices.
