Topic	Sediment: Matthews Erosion Rates from Roads Surfaces

 

Caption:  The chart above shows Matthews and Associates (2001) computed surface erosion rates from roads in the Big River basin. Matthews and Associates (2001) state: "Significant construction of new roads has led to increasing sediment yields from road surface erosion, despite improved practices." Surface erosion was computed using method of Reid (1981). Ridge roads were assumed non-delivering. See Info Links for more background information and links to references.
