Stage Control Over Forecast
This category appears at the selection of any regulation discharge method in the Regulation Discharge category, so is related to the operating level balancing approach to flood control. The selection here determines how the stage control part of the regulation discharge calculation is applied over the forecast period.
* Stage Control Varies Over Forecast
This default method selection means that each forecast timestep during the execution of regulation discharge is compared to the Stage Control Intervals periodic slot under the regulation discharge method to check if the timestep falls into a specified time interval of stage control. If it does, regulation discharge for that forecast timestep is determined under the stage control portion of the regulation discharge algorithm. If it does not, regulation discharge is calculated without stage control being applied. This determination is made separately for each timestep in the forecast period.
There are no slots specific to this method.
* Stage Control Fixed Over Forecast
This selection means that the current simulation timestep is checked against the Stage Control Intervals periodic slot under the regulation discharge method to determine if the timestep falls into a specified time interval of stage control. If it does, all timesteps in the forecast period are considered to be under stage control. If it does not, none of the timesteps in the forecast period are considered to be under stage control. This is the way that COE’s SUPER program handles this calculation.
