through soil. Infiltration is defined as the downward entry of water into the soil or rock surface (SSSA, 1975) and percolation is the flow of water through soil and porous or fractured rock. In hydrologic. modeling, these two processes are usually modeled separately. Infiltration rate is the rate at which a soil.
Soils are assigned to 4 hydrologic groups and 3 dual groups. Group A - high infiltration rate when wet, low runoff potential. Group B - moderate infiltration, low runoff potential. Group C - slow infiltration, higher runoff potential. Group D - very slow infiltration rate, highest runoff potential. The dual groups are A/D, B/D, and C/D. These are used for certain wet soils that can be adequately drained. The leading letter refers to the drained condition and the second letter is
