Table 1
Hydrological soil groups.
| Hydrologic soil group | Saturated hydraulic conductivity mm/h | Runoff generation characteristics | Soil types |
| A | >110 | Soils have low runoff potential and high infiltration rates even when thoroughly wetted | Mainly sand, loamy sand, and sandy loam | B | 14~110 | Soils have moderate infiltration rates when thoroughly wetted | Mainly silty sand and loam | C | 1.4~14 | Soils have low infiltration rates when thoroughly wetted | Mainly sandy clay loam | D | <1.4 | Soils have high runoff potential and very low infiltration rates even when thoroughly wetted | Mainly clay loam, silty clay loam, sandy clay, silty clay, and clay |
