About Unregulated Flows
Unregulated flows are defined as flows that would have occurred without the dams/reservoirs regulating the river. Other terms for these flows are uncontrolled, pre-project, and unconstrained flows. The unregulated flows are often used to compute the system benefits; that is, how much benefit has been gained by constructing the projects.
Unregulated flows are computed using the following steps.
1. Select methods to remove the effect of one or more reservoirs. When specified, the reservoir will pass inflows.
2. Run the model with the reservoirs removed and take snapshots of the desired slots.
Scripts can be used to automate this process; see Script Management in Automation Tools for details.
In the following section, we first describe how to disable the reservoir. See Model Run Mechanism, for details on how to make the runs for the regulated, fully unregulated, and partially unregulated systems.
