Abstract:

A constant-head permeameter has been modified to include the essential components of a Tempe cell moisture extractor. With this equipment, tests for saturated hydraulic conductivity permeability, unsaturated hydraulic conductivity and moisture retention characteristics of the soil can be conducted using the same soil sample. The procedure can be used for both absorption and desorption phases. Test results from four different soils a glacial till, a fine sand, a silt and a coarse sand are presented. The effects of density on hydraulic conductivity and moisture retention characteristics are shown. Author
