How to calculate the infiltration rate

Web77 4. INFILTRATION. Infiltration is the process of water entry into a soil from rainfall, or irrigation. Soil water movement (percolation) is the process of water flow from one point to another point within the soil. Infiltration rate is the rate at which the water actually infiltrates through the soil during a storm and it must be equal the infiltration capacities or the … http://hydropedologie.agrobiologie.cz/en-dvouvalec.html

Soil testing: How to measure infiltration rate effectively

WebWater from a water source passes through the top of the soil core, and the steady state flow rate is measured. That value is then used to determine the infiltration rate. Corrections are made for both constant head and falling head techniques to go from i (the infiltration rate) to a K s value (representative of a 0 pressure head influence).
