Abstract

An atlas of the hydrologic characteristics of the WolfRiver basin in West Tennessee is derived by using a Geographic Information System (GIS) to simulate the watershed's hydrologic response. A 30-meter digital elevation model (DEM), extracted from the National Elevation Dataset (NED) and managed by United States Geologic Survey (USGS), is used to develop the database of watershed characteristics. Arc Hydro, created by Environmental Systems Research Institute (ESRI), and the Geospatial Hydrologic Modeling System (HEC-GeoHMS) program, created by the United States Army Corps of Engineers’ Hydrologic Engineering Center (USACE-HEC), are used to delineate the watershed of the Wolf River basin and develop the hydrologic characteristics (physical parameters) of the main streams (creeks), such as length, slope, subbasin area, longest flow path, basin slope, centroid elevation, and centroidal flow path. These topographic characteristics were needed to analyze and evaluate every subbasin of the WolfRiver floodplain from its outlet to its headwaters. The development of an atlas that contains such information would be an invaluable source of information to municipalities and consultants in the design of storm water networks, the design of box culverts, the design of sanitary sewer systems and interceptors, the complete analysis of flood plains, and the development of a flood hydrograph for each subdivision.
