This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for measuring saturated and unsaturated hydraulic conductivity on large intact soil cores are presented. Soil horizons are wet in the field using a trickle irrigation system before excavation and sampling of the large soil cores. A convenient and accurate method for measuring saturated hydraulic conductivity suited to the large cores is then described. The same cores are used for the measurement of usaturated hydraulic conductivity at potentials close to zero. The system uses a drip infiltrometer to supply water at a constant flux. Unit gradient is achieved by adjusting the potential th the lower boundary with an adjustable outflow tube. Matric potential in the core is monitored using tensiometers and water content is measured gravimetrically. Detailed descriptions of the apparatus and calculations are presented. Alternative methods for supplying water using a constant potential device are also considered.

Baumgartner and published by . This book was released on 1994 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most procedures to measure the hydraulic conductivity of slowly permeable materials such as compacted soil liners are based on analyses that assume saturated, one-dimensional flow under steady-state conditions. The overwhelming problem, however, is the very long times, of the order of weeks or months in liner materials, to reach experimentally-measurable steady flow. A new field procedure is proposed for slowly permeable materials that takes advantage of the early transient flow in initially unsaturated soil. Both constant head and falling head techniques are proposed and measurement times are of the order of one half to several hours. The falling head technique has the advantage of requiring only the difference between the field-saturated and initial water contents in addition to the measured position of the falling head above the soil surface as a function of time. An experiment on the experimental soil liner at Champaign, Illinois, gave saturated hydraulic conductivity values using the constant head technique that were in good agreement with previously measured values. A laboratory test demonstrates the advantages of the falling head technique.
