ArcBASINS: A GIS Model for the BASINS Databaseby Kristina Antonia Schneider, M.S.E. ABSTRACT The Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) program, created by the EPA to aid in the TMDL process, provides an extensive database of environmental information. The object-oriented modeling techniques now available with Geographic Information Systems present new possibilities for modeling and organization of environmental data. This thesis explores the creation of a data model for the BASINS database, entitled ArcBASINS. The modeling techniques utilized, the two implementation methods devised for model, and some sample applications are presented. The result is a data structure that provides a standard format for the categorization and maintenance of both spatial and tabular environmental data.
