Soil Sciences: Porosity and Water Interactions

This lecture covers the concept of porosity in rocks, including the role of cracks and channels, as well as the volume fractions of gas and liquid phases in soil. It also discusses the sorption of chemicals, water retention, and the specific surface area of soil. The influence of water properties, such as its dielectric constant and surface tension, on soil behavior is explained. Additionally, the lecture explores the phenomena of capillarity and osmotic potential in soil-water interactions.
