For the past eight years, the Red River Basin (RRB) Riparian Project has been working to restore riparian zones and stabilize stream channels and banks in the Red River Valley. Since 1998, the project has completed 74 river miles of riparian restoration, developed eight restoration demonstration sites, and written 341 forest resource management plans for nearly 29,000 acres of riparian forest. Funded through the Environmental Protection Agencys Section 319 program, the project seeks to improve water quality throughout the watershed.

Project involvement in several slope failure stabilization efforts within the valley has ranged from providing geotechnical information to designing and implementing engineered restoration plans using technology such as soil bioengineering. Typically, the riparian vegetation has been removed or altered and the hydrology has been changed. Although the main goal of the Riparian Project is to restore a functioning riparian forest to act as a filter between urban or agricultural land use and the river, stabilization of active slope failures is frequently necessary before riparian restoration can be implemented. Riparian Project staff and cooperators recognized at the projects onset that understanding the causes of slope failure was essential to identifying riverbank stabilization solutions.
