The Cornell Sprinkle Infiltrometer (Ogden et al., 1997) was designed to combine the advantages of both. It also allows for easy and rapid measurement of soil infiltration, as this is essential to adequately estimate spatially and temporally-variable infiltration behavior (van Es, 1993). The Cornell Sprinkle Infiltrometer is available to in a large basin, or a very large ring infiltrometer is taken as a measure of the infiltration rate. If smaller infiltrometer rings are us^d, the. F-4 GENERAL GROUND-WATER TECHNIQUES rate of flow or subsidence for the period during which the wetting front is moving downward through the enclosed part of the soil column The double ring infiltrometer is a simple instrument used to determine the infiltration rate of water into the soil. The infiltration rate is determined as the amount of water per unit area and unit time that penetrates the soil. This rate can be calculated from the measurement results and Darcy's Law. The standard set of the double ring The single-ring cylinder infiltrometer test method with lateral f low correction is not exact, bu t in light of soil spa tial variability, the procedure yields results that a re a good estima te The automatic infiltrometer allows to maintain a small constant water head on a soil surface confined by a 150 mm inner diameter ring using a Mariotte bottle for water supply.Depending on the surface roughness, the Mariotte bottle can be regulated in height so that the surface confined by the ring is entirely submerged under a practically negligible water depth, i.e. 2-3 mm.
