This course is about learning both the principles of hydrology as well as the techniques which can be used to solve hydrologic problems. In practice, hydrologists have to quantify rates at which water is exchanged between the atmosphere, land surface, and the oceans. This often involves processing data and solving sets of equations. It is fairly easy to lose sight of the conceptual part of the problem once you focus on techniques.
Thus, one of our other goals is to give you a balanced view of hydrology--one that includes a description of the physical processes as well as a coherent presentation of the theories and techniques which are used in practice.
