WebWith the tension infiltrometer one can determine the unsaturated hydraulic conductivity. The range of tensions that can be set is (for practical reasons) limited to tensions between 0 and –30 centimetre H2O. By setting the tension at or close to zero, one could obtain an infiltration rate that approximates the saturated hydraulic conductivity. WebFigure 1 is an example of an automated Infiltrometer field setup logging two devices at the same time. The pressure transducer is connected to the AIM Automatic Infiltration Meter. The transducer will output a value relative to pressure difference between the air pressure at the top of the water tower and the water pressure at the bottom of the ...
Webwhat does an infiltrometer measure? An infiltrometer measures the infiltration of water into a substrate such as soil. Or another definition for an infiltrometer is a measure of the movement of water into, and through, soils. ... Under field conditions, it may not be known, or measurable, whether the soil or substrate is entirely free of air ...
WebPercolation, modified percolation, and double-ring infiltrometer are three types of field tests used to determine infiltration rates. In addition, a laboratory method relates sieve analysis results to an infiltration rate.
