A Geographic Information System (GIS) is a technology that aids stormwater management through efficient data manipulation, analyses, and graphic displays. The integration of GIS with stormwater management provides one-time data collection with multiple applications. A GIS creates graphical representations of basin characteristics, manages large volumes of graphical and tabular data, and aides in area calculations and other analytical aspects. Once a GIS is setup, the database can be used for water quality analyses (nonpoint source pollutant loading estimation), water quantity analyses (stormwater flows and volumes, flood level calculations), stormwater and basin master planning (land use/development schemes, floodplain mapping), and best management practice site determination (drainage and nonpoint pollutant control practices).
