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.
Tile drainage. In agriculture, tile drainage is a type of drainage system that removes excess water from soil below the surface. Whereas irrigation is the practice of adding additional water when the soil is naturally too dry, drainage brings soil moisture levels down for optimal crop growth. While surface water can be drained via pumping and/or open ditches, tile drainage is often the best recourse for subsurface water.
