Hydrologic soil group definition
Hydrologic soil group or "HSG" means a Natural Resource Conservation Service classification system in which soils are categorized into four runoff potential groups. The groups range from A soils, with high permeability and little runoff production, to D soils, which have low permeability rates and produce much more runoff.
Hydrologic soil group means the classification system for soil erodability set out in Soil Survey — San Diego Area, California (December 1973), issued by the U.S. Department of Agriculture Soil Conservation Service and U.S. Forest Service. In this system soils are categorized into four runoff potential groups. The groups range from "A" soils, which have high permeability and little runoff production, to "D" soils, which have low permeability rates and produce much more runoff.
Hydrologic soil group means a group of soils having similar runoff.
More Definitions of Hydrologic soil group
Hydrologic soil group means a Natural Resource Conservation Service designation given to different soil types to reflect their relative surface permeability and infiltrative capability. Designations consist of four classifications (A, B, C, and D) grouped according to soil infiltration rates from high infiltration rates in Group A to very low infiltration rates in Group D.
