THE INFLUENCE OF SOIL PROPERTIES ON THE WETTING-UP OF EARTH STRUCTURES

Soil characteristics affecting wet season infiltration and drainage of earth structures are reviewed and the form of mathematical description which is considered to be most closely identified with simple physical properties is selected for further study. Available soil moisture characteristics are analysed to provide a guide to common values of the parameters which are required to describe the characteristics. The influence of these parameters on numerical model predictions of infiltration from a saturated boundary is then investigated in detail and summarised concisely to show how parameters affect the progression and shape of the wetting front. The conclusion presents recommendations for parameters to be used for the production of concise illustrations of how various other design parameters influence wet season moisture movements in earth structures.
