摘要：Watershed prioritization is one of the important aspect in watershed management. Implementation of watershed development programme in the entire watershed, at a time, may not be possible due to lack of resources, including financial resources. So, the watersheds need to be prioritized for taking up the developmental activity, based on the severity of the problems in the watershed. There are various criteria for prioritizing the watersheds based on its physical and socio-economic characteristics. Ministry of Rural Development, Govt. of India, is responsible for providing the policy guidelines for watershed development, has emphasized different criterion to prioritize the watersheds for taking up under watershed development programme in the country. This study has concentrated by taking one of the criteria i.e. socio-economic characteristics for prioritizing the watersheds towards soil and water conservation in an automated way. The authors have developed a package called 'SWaP' for the purpose. SWaP stands for S howcase for Wa tershed P rioritization. SWaP is a menu driven shell for watershed prioritization developed using a Macro Language of COTS GIS package. It generates watershed priority map in an automated way using minimum of one or maximum of six parameters. The parameters considered in this model are percent SC/ST, percent wasteland, percent forest land, drainage density, percent slope and drinking water facility. All input coverages are required in NNRMS standards developed by Dept. of Space, Govt. of India. As per this model, each and every parameter is weighted and normalized with respect to minimum and maximum values in the watershed area. Then, the ranks are assigned to the categories within each parameter depending upon its significance related to development. The weightage and ranks multiplied to get index for individual parameters. Watershed priority index (WPI) is then calculated by summing up the values of all parameters indices. Finally, the WPI is divided into four classes of priority based on mean and standard deviation to get watershed priority map
