- Dependence:
- In this case the current output is determined by requests from the underflow of a reservoir. A defined discharge should not fall below a defined flow rate at a cross section of a watercourse in the water resources system, which is called control point in the following and which is influenced by reservoir discharges. The outflow at the control point is composed of the discharge from reservoirs and the lateral inflows lying in between. If the current outflow remains below the setpoint, an additional flow from above lying storage tanks is necessary. The amount of the allowance depends on the difference between the target flow and the actual flow. Whether the required allowance can be fully provided from the storage unit depends on the current storage unit content, because the lower the filling is, the less favorable it is to have to provide additional water. In this context, the low water increase/demand behaves completely identical to drinking or raw water withdrawal, only the triggering factor differs. As mentioned before, a storage-dependent function is scaled by a factor, but this factor is now derived from a comparison between set values and current discharges.
