Course/Module description:
Soil-water relations. Measurement of soil-water content. Hydrostatics Osmotic pressure. Surface tension. Soil-water retention curves. The hysteresis phenomenon. Diffusion and mass transport. Darcy's Law. Flow in confined and unconfined layers. Unsaturated flow. Hydraulic conductivity in saturated and unsaturated soils. Infiltration and evaporation from soils. Water content profiles under wetting and drying processes. Water availability to plants.
Course/Module aims:
Providing basic understanding of the processes controlling water retention and flow in soils, including basic principles/definitions and simple models to describe the forces acting on water in static and dynamic (flow) conditions, at saturated and unsaturated conditions.
Learning outcomes - On successful completion of this module, students should be able to:
Understand the very basic principles and concepts that are required for quantitative description of water retention and flow in saturated and unsaturated conditions.
