AREN 309: Soil and Water Engineering

Introductory Concepts: soil water potential concepts; potential distribution of soil water under field conditions; methods of soil water determinations; soil water retention curves; hysteresis. Soil Water Flow: flow of water in model systems - tubes and pipes; darcy’s law; transport of soil water under saturated conditions; transport of soil water under unsaturated conditions; determination of hydraulic conductivity. Soil Water Flow Processes in the Field: infiltration; runoff; internal drainage and redistribution; evaporation. Basic concepts of soil erosion; control of soil erosion; Mechanics of wind and water erosion; water and wind erosion control practices; concept of runoff and its estimation
