Hydrologic soil group infiltration rates
WebThese soils have a moderate rate of water transmission (0.15 to 0.30 in./hr.). Group C Group C soils have low infiltration rates when thoroughly wetted and consist chiefly of soils with a layer that impedes downward movement of water and soils with moderately coarse textures. WebHydrologic soil groups A and B have high and moderate infiltration rates. Group A soils are deep, well drained sands while Group B soils are deep, moderately to well drained soils that have a moderately fine to moderately coarse texture. These two groups are well suited for longleaf pine. Group C soil have slow infiltration rates when wet.

WebHydrologic Soil Groups • NRCS Soil Scientists have classified soils into four hydrologic soil groups – Group A – Low runoff potential and high infiltration rates even when thoroughly wetted. Mostly sands and gravels that are deep, well drained to excessively drained with a high rate of water transmission (>0.30 in/hr).
