AssignmentsExercises are started in class and completed at home.

TestsThree hourly tests plus optional comprehensive make-up test.

The optional make up test allows you to improve your score on questions from the first three tests.

There are now many hydrology texts. Each is best for part of the course. Physical Hydrology has the best chapters on meteorology. Elementary Hydrology is strong for hydrologic techniques. Applied Hydrogeology has the strongest geology chapter. Fundamentals of Ground Water is strong on ground water. Physical and Chemical Hydrogeology is strongest in water quality.
