Objective
- Learn the principles and mechanisms of water-soil interaction.
- Learn the physical principles and concepts that govern water dynamics in the soil root zone
Content
Surface tension and capillarity. Water structure. Retention of water in the soil. Basic measurements in
the solid-solution-air systeml: fundamental physical units; soil porosity; aeration porosity; soil water
content; soil water storage. Thermodynamics of water in soil. Soil water potentials. Measures of soil
water potentials. Movement of water in the soil: movement under saturation and non-saturation
conditions; Darcy equation and Darcy-Buckingham equation; continuity equation. Infiltration of water in
the soil; infiltration law; flow equations for infiltration. Redistribution of water in the soil: description and
analysis of the process. Soil hydraulic conductivity: laboratory and field methods; mathematical
equations; methodological implications. Water balance in vegetated soil.
