When to Use Multiple Watershed Configurations in HEC-ResSim

For many studies involving ResSim, various operating criteria are applied to an existing system.  In this post, I provide an example of using multiple watershed configurations to study the addition of a new reservoir to the system.

The figure below shows the existing system.  In this system, there is a single reservoir located on the main stem.  This configuration is named "existing system".




We can look at the details of this configuration.  Notice that the reservoir is listed as being an existing reservoir.



To model a proposed reservoir on the tributary, we can save this configuration under the name, "proposed system" and add a reservoir on the tributary.



When looking at the details of this configuration, we notice that the proposed reservoir is not listed as being an existing reservoir.
