WaterBase: SWAT in an Open Source GIS

Abstract

W aterBase is a project of the United Nations University. Its aim is to advance the practice of Integrated Water Resources Management (IWRM) in developing countries, by providing (a) free, open source tools for modeling and decision support (b) a collection of IWRM resources: web sites, tools, literature, training material, etc. and (c) a community of partners who can provide advice, support, contribute to tools and resources. A first step in the project is a tool to provide Geographic Information System (GIS) support and a setup interface for the Soil and Water Assessment Tool (SWAT). This paper describes the design of this tool, called Map Window SWAT (MWSWAT).
