PWTB 200-1-43 Method for Identifying Roads and Trails to Determine Erosion Potentials on U.S. Army Installations  

Date: 
03-31-2008

This Public Works Technical Bulletin (PWTB) describes a Geographic Information System (GIS) software package for identifying unimproved roads and trails to determine erosion potential on U.S. Army installations. The GIS layers required for the software are elevation, vegetative cover, and soils which are standard GIS data sets available for most U.S. Army installations. In addition, users may wish to populate layers that allow site orientation within the program, such as roads, installation boundaries, county boundaries, bodies of water, and aerial photograph layers. Erosion potentials estimated by the software program are compared to on-site assessments at Camp Atterbury, IN, to validate the software calculations with field collected data. Appendix F gives a step-by-step procedure for using the software package.
