Abstract
Soils in nature are highly variable in their physical, chemical and biological properties. One contributor to soil heterogeneity
is water repellence. This thesis is directed at investigating how heterogeneous water repellence affects the water and energy balances near soil surface by undertaking novel experiments to non-invasively assess infiltration, redistribution and evaporation processes. A non-destructive method to monitor the dynamic is demonstrated here. This study demonstrated that the evaporation rates depend upon the spatial pattern. This work also improves the understanding of water flow at the interface of repellency though non-destructive measurement methods such as 3D X-ray microtomography and thermography.
