Topic Sediment: Matthews Erosion Rates from Roads Surfaces

Caption:  The Chart Table sediment_road_surferosion_rates_all.dbf was derived from Matthews and Associates (2001) Table 29. Surface erosion rates (tons/yr) were computed using method of Reid (1981) based on use function analysis (High, Moderate, Low, None) and application of sediment production rate (800, 80, 8, 0.8 tons/yr) modified by surfacing factors (.2, .5, and 1.0 for paved, rocked, and native surfaces, respectively) and by location delivery factors (0.8 for riparian roads within 200 of a stream course, and 0.2 for mid-slope roads). Ridge roads were assumed non-delivering. Each period of analysis spans back to the previous aerial photo year. See Info Links for more information. BASIN = Matthews sub-basin naming convention, SHORT_NAME = abbreviation for use on charts. Y19## = surface erosion rate (tons/yr) for the year of the aerial photos used in the calculation.
