Understanding the topography of the Dog River Watershed is important in identifying areas subject to erosion, deposition, and flooding. Because topographical maps are difficult for most people to accurately interpret, a raised relief map provides a better visual representation for educating the populace. A raised relief map was constructed using 7.5 minute topographic quadrangles covering the Dog River Watershed.
Layers correspond to the fifty foot index contour intervals.
The layers are differentiated enough to give a clear picture of what the watershed in the Mobile County area looks like in three dimensions. In almost all cases the raised map was more easily read and understood than the flat map. The educational ramifications of this project are very diverse, going from presentational use to classroom display. Introduction The Dog River Watershed is located in and around the Mobile City area. Its elevation ranges from sea level to over 200 feet above sea level.
