Description

What is channel stabilization?

Channel stabilization involves reshaping a streambank with a stable slope and installing structural and bioengineering techniques, such as riprap or permanent vegetation. By increasing infiltration, slowing surface runoff, and increasing water storage, channel stabilization reduces the streamflow by 5% and decreases the risk of downstream flooding. Water quality is improved with a 70% reduction in sediment load and a reduction in nutrient loading with less in-channel scouring and bank erosion. Wildlife habitat is provided in riprap and vegetation and the reduction in sediment loading enhances the stream environment for fish. Channel stabilization improves the aesthetic beauty of the stream and conserves agricultural land.
