The Geomorphic Road Analysis and Inventory Package (GRAIP) is designed to help land managers learn about the impacts of road systems on erosion and sediment delivery to streams. As the name implies, GRAIP couples analytical tools with an inventory process to build an approach to roads analysis that can be locally calibrated in a repeatable fashion and with minimal effort. The full scope of GRAIP includes methods to inventory roads and analyze the inventory for surface erosion, gully risk, landslide risk and stream crossing failure risks. Methods to measure road surface erosion from sample sites are also included. Please explore the resources section along the right for more detailed information.
GRAIP is a detailed road inventory procedure and modeling toolset for understanding the various site specific impacts of forest roads on water quality. If you are looking for a more general prioritization tool that can be applied over a broader area without the cost for intensive field data, then GRAIP_Lite may be a good choice.
