This GIS-based tool is designed to map all of the areas that are important to the sediment and water processes in a river at a large scale. Analysis is very basic but incorporates fluvial processes, groundwater processes, and sediment processes. Each process is modeled using a separate set of GIS steps and the resulting maps are combined.
