Topic	Sediment: Matthews Erosion Channel Banks (vol/yr) for NF Big

 

Caption:  The chart above shows fluvial erosion rate estimates for Class 1 and Class 2 streams in the North Fork Big River watershed as determined by Matthews and Associates (2001). The classes refer to the California Department of Forestry convention where perennial fish bearing streams are Class 1, perennial non-fish bearing streams are Class 2 and intermittent streams are Class 3. Class 2 streams are afforded less protection from timber harvest than Class 1 streams are and they also yielded more erosion except for the Lower North Fork. See Info Links for more background information and links to references.
