CE/ENVE 320-03 provides the theoretical and experimental foundation for understanding and quantifying physical and hydrological properties of soils and other porous media. The course covers key hydrological processes taking place at or near the earth's surface, emphasizing mass and energy exchange, transformation and transport in partially-saturated porous media at multiple scales. Coupling with atmospheric processes and the role of plants in the hydrological cycle will be studied. We will examine modern measurement methods and the commonly employed analytical tools for data collection and interpretation of hydrological information. The course provides conceptual and practical tools for addressing vadose-zone related science and environmental engineering challenges.
