  The measurement of water infiltration in the soil is an important indicator of the efficiency of irrigation and drainage, optimisation of water availability for plants, improvement in the harvest yield and erosion reduction.
  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 quantity of water which penetrates the soil per surface area and time unit. This rate can be calculated using the measurement results and the law of DARCY. The standard set of the double ring infiltrometer consists of a few sets of stainless steel rings with different diameters (for transport reasons). Several measurements may be conducted simultaneously which leads to an extremely reliable and precise average result. If vertically infiltrated water flows off naturally, the outer ring serves as separation protection. The measurements take place exclusively in the inside ring through which the water flows virtually vertically. In order to achieve good measurement results, it is important to consider the different factors influencing the measurements: the surface vegetation, the degree of soil compactness, the soil moisture content and the soil properties such as horizontalisation (strata). The best results are achieved with the “field capacity” of the soil. The ring infiltrometer may be used for the following purposes amongst others: irrigation and drainage projects, run-off investigations, determination of the intensity of precipitation and of the effects of soil working measures.
