A synoptic approach for analyzing erosion as a guide to land-use planning
William M. Brown III, Walter G. Hines, David A. Rickert, Gary L. Beach
1979, Circular 715-L
A synoptic approach has been devised to delineate the relationships that exist' between physiographic factors, land-use activities, and resultant erosional problems. The approach involves the development of an erosional-depositional province map and a numerical impact matrix for rating the potential for erosional problems. The province map is prepared by collating...
