Surface-Positioned Double-Ring to Improve Traditional Infiltrometer for Measuring Soil Infiltration
Soil Research, 2020The installation of a traditional double-ring infiltrometer (DRI) into soil is difficult and time consuming. It results in reduced accuracy because of soil disturbance and water leakage along the gaps between the ring wall and the soil. In this study, a surface-positioned DRI (SPDRI) was suggested to improve measurement accuracy and convenience of the ...

Soil Use and Management, 2010
Abstract Estimating soil hydraulic properties, such as infiltration rate and hydraulic conductivity, is important for understanding hydrological processes such as rainfall and irrigation partitioning. Current infiltrometers can require considerable operator input to limit the number of readings that can be ...

INVESTIGATION OF THE EFFECT OF DOUBLE RINGS INFILTROMETER DIMENSION ON INFILTRATION RATE
Gashua Journal of Irrigation and Desertification Studies, 2016Overestimation of vertical infiltration rate as a result of diverges laterally flow is a major problem in the use of infiltrometers. Although, the double-ring infiltrometer minimizes the error associated with lateral divergence, no specific dimension has been given for its usage.

Sand‐Model Study of Buffer Effects in the Double‐Ring Infiltrometer
Soil Science Society of America Journal, 1961Abstract Infiltration of water has been studied for a wedgeshaped sand model built as a sectorial portion of the double‐ring infiltrometer flow system. Determinations of infiltration velocity for localized portions of the flooded sand surface permit the assessment of buffer effects.

Development of an automated double-ring infiltrometer
Australian Journal of Soil Research, 1996A double-ring infiltrometer is often used for measuring infiltration characteristics in the field, but the measurements are time-consuming and tedious, especially when several tests are to be monitored at a site. This is because the infiltrometer in its present form requires continuous attention and therefore limits the number of tests that can be ...

Sealed Double-Ring Infiltrometers for Estimating Very Low Hydraulic Conductivities
Geotechnical Testing Journal, 2005Abstract Sealed, Double-Ring Infiltrometers (SDRIs) are one of the preferred devices to measure infiltration rates of soil liners in the field. Existing SDRIs are well suited for measuring infiltration rates on materials with hydraulic conductivities on the order of 1 × 10−9 m/s. A very low hydraulic conductivity material (<1 × 10−
