Soils and infiltration….
{"Image DocumentName": "Soils and infiltration\u2026.", "Image ImageDescription": "Factors that control infiltration rate and capacity: Vegetative cover, root development, and organic content. Moisture content. Soil structure and texture. Porosity and permeability. Soil bulk density and compaction. Slope, landscape position, and topography. Hydrologic soil group (HSG). The HSG refers to the soil characteristics that tend to decrease or increase the amount of runoff produced from a precipitation event. The HSG is used in the determination of the runoff curve number (CN) developed by the Natural Resource Conservation Service (NRCS). Group A. Sand, loamy sand, or sandy loam soil types. Low runoff potential and high infiltration rates, even when thoroughly wetted. Includes deep and well- to excessively-drained sands and gravels. High rate of water transmission (hydraulic conductivity). Group B. Silt loam or loam. Moderate infiltration rate when thoroughly wetted. Includes moderately deep to deep, moderately well- to well-drained soils. Moderately fine to moderately coarse textures.
