A soil infiltrometer is a device used to measure the rate at which water infiltrates into the soil. That is, how quickly water moves from the surface in the field into the ground. Infiltration rate equals the change in water depth on surface divided by time. Time intervals measurements are typically every 5 to 10 minutes. It is widely used in agriculture, hydrology, environmental science, ...
