This has been the historical method of measuring hydraulic conductivity based on the gravity flow of a retained water column. The measure of infiltration of water into the soil is an important indication concerning the efficiency of irrigation and drainage, optimising the availability of water for plants, improving the yield of crops and minimising erosion. The double ring infiltrometer is a simple instrument that is used to determine the rate of infiltration of water into the soil. The rate of infiltration is determined as the amount of water per surface area and time unit, that penetrates the soil. This rate can be calculated on the basis of the measuring results and the Law of Darcy.
The standard set of the double ring infiltrometer consists of a number of sets of stainless steel rings with different diameters (for reasons of transportation). Several measurements can be executed simultaneously, yielding a very reliable and accurate mean result. Measurements can be taken from the surface only.
