Website Pointer to Geomorphic Road Analysis 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. The road inventory protocol describes how to systematically field inventory a road system using GPS and automated data forms.
