Water quantity and water quality are two of the most pressing environmental issues of the 21st Century. This course is designed to provide an introduction to the field of hydrology and will cover the fundamentals from an earth science perspective. We will focus on hydrological processes and the resulting spatial and temporal patterns of precipitation, evaporation, and runoff at scales ranging from the plot to hillslope to watershed scale. Since hydrology is a quantitative discipline, weekly lab exercises will complement text readings and lectures by providing an introduction to hydrological analysis. Your TA and I will strive to get to know you as best we can. We will be available after class to answer questions or address concerns.
