the laboratory determination of three different soil's permeabilities (hyd raulic. conductiv ity, k), this paper shows that for sandy-silty soils: 1) The Double -ring infiltrometer (DRI) yields The infiltration capacities (IC) of three different sands were measured repeatedly in a laboratory using a double-ring infiltrometer (DRI) and the Cornell Sprinkle Infiltrometer (CSI). The study assessed (1) the level of agreement between the infiltrometers, and (2) the reproducibility of values produced by each infiltrometer. Double Ring Infiltrometer This is a simple, inexpensive method for determining permeability of soils. The infiltration rate is controlled by the least permeable zone in the subsurface soils. With the Double Ring Infiltrometer, it is easy to test several areas of a large tract to find the infiltration rate. It also prov. Infiltration equation of the soil is obtained by conducting a double-ring Infiltrometer test. The Kostiakov infiltration equation fitted is in the form y=0.44t 0.65. The basic infiltration rate is Download as PDF; Printable version Single ring infiltrometer Double ring infiltrometer. An infiltrometer is a device used to measure the rate of water infiltration into soil or other porous media. Commonly used infiltrometers are single-ring an inner and outer ring. The purpose is to create a one-dimensional flow of water from the inner Soil samples and water samples at the site of sprinkler irrigation are collected and analyzed. Infiltration equation of the soil is obtained by conducting a double-ring Infiltrometer test. The Kostiakov infiltration equation fitted is in the form y=0.44t 0.65. The basic infiltration rate is 44 millimeters/hour.
