(HP-67) Soil Horizon Depth Correction Based on Slope Gradient
An extract from the Program Description of Soil Horizon Depth Correction Based on Slope Gradient, Gordon Warrington, USDA Forest Service, Technical Notes WSDG-TN-00001, DEC 1980, 10 pages.

… reasons for reporting depths of soil horizons on steep terrain, as distances that are perpendicular to the soil surface … On steep slopes … the differences between vertical measurements … perpendicular measurements … can be important … interpretations and taxonomic classification. Water holding capacity and other soil properties … overestimated … procedure … adjust vertical depth measurements to distances … perpendicular to a soil surface …
