Field Measurements in Soil Mechanics

Open field soil moisture measurements with Radar

-As reported in [1], the Material Characteristics in Frequency Domain coupled with a 2 layer feed-forward Neural Network, MCFD/NN, has been successfully applied to soil moisture determination. The results were obtained under controlled laboratory conditions. Extension to open field soil moisture determination has been reported in [2] and it was shown that the MCFD/NN approach gives accurate res...

Soil Compaction and Soil Tillage – Studies in Agricultural Soil Mechanics

Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...

Soil mechanics: breaking ground.

In soil mechanics, student's models are classified as simple models that teach us unexplained elements of behaviour; an example is the Cam clay constitutive models of critical state soil mechanics (CSSM). 'Engineer's models' are models that elaborate the theory to fit more behavioural trends; this is usually done by adding fitting parameters to the student's models. Can currently unexplained be...

ring size dependence of field saturated hydraulic conductivity measurements in a clay loam soil

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...
