This module helps students gain a basic understanding of the elements of the hydrologic cycle. Making use of illustrations, animations, and interactions, this module examines the basic concepts of the hydrologic cycle including water distribution, atmospheric water, surface ... Read more »
The Runoff Processes module offers a thorough introduction to the runoff processes critical for flood and water supply prediction. Through the use of rich illustrations, animations, and interactions, this module explains key terminology and concepts including paths to ... Read more »
The role of unit hydrograph theory in the flood prediction process is to provide an estimate of streamflow given the precipitation. A unit hydrograph shows the temporal change in flow, or discharge, per unit of runoff from excess precipitation. In other words, the unit ... Read more »
