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.
The less water the ground can absorb, the more runoff on the surface there will be. This is called permeability. A surface with high absorption ability has high permeability, and a surface with low absorption ability has low permeability. This image shows permeability rates for different types of surfaces (see video).
