Introduction to Hydrology

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.

Lecture Topics - General Outline:

Introduction   - water issues, why hydrology is important vis-à-vis climate and land use change
Water balance - hydrology’s most fundamental equation; watersheds, watershed scaling laws
Precipitation - types of precipitation, global and regional patterns, measurement, areal estimates, statistics
Interception - interception storage, throughfall, stemflow
Evaporation  - evaporation from free water surfaces, bare soils, and vegetation covers, regional patterns
Soil water  - infiltration, soil moisture content, soil moisture profiles, forces on soil water, soil moisture characteristics, hydraulic conductivity, Darcy’s Law, soil water flow
Groundwater  - groundwater table, capillary fringe, aquifers and aquitards, unconfined and confined aquifers, groundwater flows
Runoff - discharge, runoff generation, Horton overland flow, saturation overland flow, subsurface flow, role of groundwater, temporal variations in discharge, runoff statistics, snowmelt runoff, Canadian runoff regimes
