Topic	Sediment: Matthews Erosion Rates from Harvest Areas LNF 1921-2000

Caption:  The Chart Table sediment_surf_harvest_period_all.dbf was derived from Matthews and Associates (2001) Table 33. The BASIN is the Matthews sub-basin naming convention, SHORT_NAME is the abbreviation for use on charts and the years (i.e. Y1936) are the year of the aerial photos used to estimate the number of landslides. Each period of analysis spans back to the previous aerial photo year. Values represent tons of sediment. See Info Links for more information.

 50 rows of a possible 56 have been displayed.
