Caption:  The Source Table sediment_road_surferosion_rates_all.dbf was derived from Matthews and Associates (2001) Table 29. The BASIN is the Matthews sub-basin naming convention and the years (i.e. Y1936) are the year of the aerial photos used in the analysis and list erosion rates in tons/yr. Each period of analysis spans back to the previous aerial photo year. See Info Links for more information.
