Web• 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). WebNRCS offers technical and financial assistance to help producers plan and implement conservation practices that prevent soil erosion and degradation and improve soil health. …

WebThese consist mostly of soils that are moderately deep to deep, moderately well drained to well drained with moderately fine to moderately coarse soil textures. These soils have final infiltration rates of 0.15 – 0.30 in/hr (3.8–7.6 mm/hr). Group C: Soils with slow infiltration rates when thoroughly wetted. WebLecture 16 14-September-2016 NRCS METHOD TO DETERMINE SURFACE RUNOFF: In the last class, we introduced to you the NRCS method. Recalling the terms, WebThe infiltration rate is the velocity or speed at which water enters into the soil. It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the soil surface, will take one hour to infiltrate. In dry soil, water infiltrates rapidly. launch pad chch
