Comparison of Cornell Sprinkle Infiltrometer and Double-Ring Infiltrometer Methods for Measuring Steady Infiltration Rate

Soil Science Society of America Journal, 2021
Abstract Infiltration rate measurements are used to assess soil health and develop land management practices to address runoff from precipitation and irrigation. Differences in observed infiltration rates determined by available methods can be attributed to both the technique and soil property differences.

Surface-Positioned Double-Ring to Improve Traditional Infiltrometer for Measuring Soil Infiltration

Soil Research, 2020
The 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 ...

INVESTIGATION OF THE EFFECT OF DOUBLE RINGS INFILTROMETER DIMENSION ON INFILTRATION RATE

Gashua Journal of Irrigation and Desertification Studies, 2016
Overestimation 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, 1961
Abstract 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, 1996
A 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, 2005
Abstract 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−

A test of the single‐ and double‐ring types of infiltrometers

Eos, Transactions American Geophysical Union, 1956
The results of field experiments with ring‐type infiltrometers are reported. Infiltration rates obtained with the rings were compared to the infiltration rates obtained by flooding the entire area to determine the number of ring measurements required to characterize the infiltration rate of the area.

Discussion of “A Test of the single‐ and double‐ring types of infiltrometers”

Eos, Transactions American Geophysical Union, 1957
The use of single‐ and double‐ring infiltrometers to determine infiltration rates is becoming widespread. Articles such as this are extremely timely. These investigators found that single‐ring and double‐ring infiltrometers gave about the same value on a uniform Yolo silt loam with a soil profile having no layers restricting the downward movement of ...
