This course provides an introduction to the field of hydrology along with fundamental watershed concepts. Rainfall runoff models cover the rational formula, SCS method, frequency analysis of extreme flows, regional analysis, low-flow analysis, and measurement of snow melt. The hydrometric section includes procedures used to construct hydrographs and hydrometers, methods to determine stage flow and various measures of streamflow. Assignments and labs involve using maps to characterize hydrology, hydrograph analysis, and land use effects on hydrology. The course emphasizes techniques used in the measurement of hydrologic data, including hydrometric station instrumentation. A field trip may be included depending upon the weather.
