SEDMODL

Sediment Model 2 (SEDMODL2) is a GIS-based road erosion and delivery model designed to identify road segments with high potential for delivering sediment to streams. The model uses an elevation grid combined with road and stream information layers to produce what is essentially a computer-generated version of the Washington surface road erosion model. It estimates background sediment, generation of sediment for individual road segments, finds road/stream intersections, and estimates delivery of road sediment to streams.
