|Double Ring Infiltrometer Test
|The double-ring infiltrometer Test (DRIT) is commonly used for measuring soil hydraulic conductivity. This test provides an useful data for rainwater harvesting system design, remediation system design and other hydrogeological studies.
|How Does it Works
|A double ring infiltrometer requires two rings: an inner and outer ring. The ASTM standard method specifies inner and outer rings of 30 and 60 cm diameters, respectively. The rings are partially inserted into the soil and filled with water, after which the speed of infiltration is measured. The measured infiltration rate is approximately equal to the saturated hydraulic conductivity.
