Caption:  The Chart Table sediment_roads_surferosion_nf.dbf is from the Source Table, 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 contain road surface erosion rates (tons/yr). Each period of analysis spans back to the previous aerial photo year. See Info Links for more information.

 50 rows of a possible 125 have been displayed.
