GRAIP Case Studies

Legacy Roads Monitoring Project

The Legacy Roads Monitoring Project is designed to determine the degree to which road decommissioning and maintenance treatments are effective in reducing impacts to key watershed processes. Intensive field inventories and modeling are used to develop and compare road risk/impact profiles before and after road treatments and after storm events.


Watershed Studies

GRAIP watershed studies are used to characterize the level of risk associated with the road network in critical watersheds.  GRAIP provides site specific predictions of road surface erosion, sediment delivery, hydrologic connectivity, stream crossing failure and diversion risk, as well as maps of landslide and gully initiation risk.  The GRAIP outputs empower land managers with the site specific data required to prioritize restoration efforts and to maximize benefits to the aquatic system.
