Tools

Geomorphic Road Analysis and Inventory Package (GRAIP)

The U.S. Forest Service Rocky Mountain Research Station sponsors the Geomorphic Road Assessment and Inventory Package (GRAIP). GRAIP is a process and a set of tools for analyzing the impacts of roads on forested watersheds. GRAIP combines a road inventory with a powerful GIS analysis tool set to predict sediment production and delivery, mass wasting risk from gullies and landslides, stream diversion potential, culvert maintenance, and fish passage at stream crossings.
