WR574 Snow Hydrology

Fall 2007 Summary: Snow processes and their relation to the hydrologic cycle, including cloud processes and precipitation formation, snowfall, accumulation, snowcover, canopy interception, redistribution, sublimation, snowpack metamorphosis, and snowmelt. Physical and conceptual methods of modeling and techniques for measuring the different states and change rates. New and innovative modeling and measuring techniques.

Course Objectives: A successful student will be able to measure snowpack properties and estimate the error associated with the measurements, estimate the winter water balance, model snowpack hydrological processes, and manipulate a large time series of data (~10,000 time steps). syllabus
