Soil Water Dynamics: Physical Aspects

This lecture by the instructor, Andrew Barry, focuses on the physical aspects of soil, particularly on what controls water movement in soil. The lecture covers topics such as soil texture, structure, density, porosity, and specific surface area. It also delves into the importance of soil structure in influencing fluid movement, the concept of cation exchange capacity, and the role of soil in the water cycle and carbon storage. The instructor emphasizes the complexity of soil as a porous medium and how physical laws govern water movement in soil.
