Methods for Computing Watershed Yield
Credits: 2 PDH
PDH Course Description:
This course outlines the methodologies used to compute water yield for a given site's watershed. Watershed yield can apply to either a long-term average (e.g., 1971–2000 average annual streamflow) or can be synonymous with runoff volume for a specific
period (e.g., flow for May 1999). The period referred to is most often either a year or a month, but one could also consider a day or any other period in between.
Topics:
- The water balance equation
- The use of runoff maps for computing water yield
- The use of regression equations when computing water yield
- The use of the water balance equation to compute water yield
- Reservoir storage planning
- Supply-demand relationship
- Streamflow, precipitation, and evaporation data sources
