Field Scale Water Content Measurement by TDR Techniquechnique is based on the propagation of electromagnetic waves through a transmission line consisting of two rods inserted in the soil horizontally and on the interpretation of the reflected signal for the assessment of the water retention curve. The lack in precision determined by the signal attenuat

Use of TDR Probes to Measure Water Content in Pumiceous Soilsy to determine soil properties depends on the proper understanding of the parameters that affect the propagation of an electromagnetic pulse along the TDR wave guide. Dielectric permittivity measurements in coarse grained soils indicate that the determination of the apparent relative permittivity of

Observations from Borehole Shear Testing in Unsaturated Soil in clayey soils, the failure envelope from the BST may yield a friction angle and cohesion intercept in agreement with effective stress strength parameters determined from laboratory tests. Generally, this occurs when the in situ soil is in a nearly saturated condition and where shear-induced exces

Soil Fabric of Compacted and Natural Swelling Soils Studied by Mercury Intrusion Porosimetryinitial state. The soil fabric of these clayey soils including the macropores, mesopores, and micropores was mainly studied by the mercury intrusion porosimetry (MIP) technique. For both soils, the results showed clearly that the soil fabric of the remoulded samples compacted in the laboratory are s

Water Retention Behaviour Explored by X-Ray CT Analysis 3D images, local and global values of porosity and degree of saturation are then measured. This method enables the study of water retention behaviour of sand at the grain scale, all the while allowing characterisation of water retention in the sample as a whole.

Observations from Borehole Shear Testing in Unsaturated Soiln unsaturated clayey soils at two test sites. Results indicate that soil suction, in addition to other test variables, has a strong influence on failure envelope. Range of normal stress used in the test was also observed to have a strong influence on the resulting Mohr-Coulomb failure envelopes.
