• Dependency:

In this case, the current discharge is determined by conditions downstream of a reservoir. At a cross-section of a water resources system, the so-called control point, where the flow is dependent on the discharge from the upstream reservoir, a minimum flow is defined. The flow at the control point is composed of the discharge from reservoirs and the lateral inflows lying in between. If the current flow remains below the set minimum, an additional discharge from upstream reservoirs is necessary. The volume of the additional discharge depends on the difference between the previously defined target flow and the actual flow. Whether the required discharge can be fully provided from the reservoir depends on the currently available stored volumes in the reservoir, as the lower the level, the less favorable it is to provide additional water. In this context, the increase of low water/coverage of demand behaves completely identical to the drinking or service water withdrawal, with only the triggering factor differing. 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.
