|3 credits. Exploration of the roles of natural processes and anthropogenic activities in regulating the quantity, distribution, and chemical composition of the Earth's freshwater. Students gain exposure to theoretical and applied elements of surface and subsurface hydrology. The theory covered in the course focuses on hydrologic phenomena of societal and environmental importance, including stream-flow generation, wetland-water cycling, groundwater-flow dynamics, contaminant migration in surface and groundwater, and water use and redistribution by plants. Application of theory is accomplished through student use of hydrologic simulation models, which are expressions of theory and essential tools of water-resource management and assessment. Intended as a first course in scientific hydrology; appropriate for M.E.M., M.E.Sc., and Ph.D. students, as well as for advanced undergraduates.
