Caption:  The Chart Table slides_debris_landuse_allsubs.dbf was derived from Matthews and Associates (2001) Table 17. The LAND_USE is the Matthews land-use naming convention and the years (i.e. Y1936) are the year of the aerial photos used to estimate the number of debris torrents per land-use practice. 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.
