This chapter presents applications of Arc View Geographic Infonnation System (GIS) in developing SWMM (Storm Water Management Model) computer models. Three types of Arc View applications are presented: intercbanging, interfacing, and integrating. Interfacing or integrating SWMM models with GIS can significantly improve the modeling efficiency because a GIS environment provides a modeler with efficient model development, execution, and analysis tools. Arc View is a user-friendly desktop mapping

... nd GIS program which can be learned by most modelers without extensive training and experience. A venue, ArcView's object-oriented development language, can be used to interface or integrate Arc View and SWMM software. Due to its low cost, ease of use, and Avenue programming capability, ArcView is a suitable tool for developing SWMM interfaces and integrations. This chapter describes how Arc View can be used to develop SWMM computer models. The chapter also provides a software review of available SWMM/GIS interfaces. The advantages and limitations of various techniques are identified and recommendations for future research and development are made from a user's perspective.
