Topic	Sediment: Road-Related Erosion Sources by Volume in Mill Cr 1998-99

 

Caption:  This Chart shows future sediment yield from road-related potential erosion sites in Mill Creek, based on data collected during road surveys. Erosion from Stream Crossings, Landslides, and Other are sudden events, and their future sediment yield is calculated by multiplying total potential erosion by the probability of delivery to a stream. Persistent Surface Erosion is the gradual process of road wearing, and is estimated by multiplying the road and cutbank surface area by 0.2 inches per year over a 10-year period. Nearly all sites inventoried were recommended for treatment. Data were provided by the Mendocino County Resource Conservation District and Pacific Watershed Associates (1999). See Info Links for more information.
