Minimum Flow Requirement Node Flows

A minimum instream flow requirement (FR), which is entered as data (see Supply and Resources\River\Flow Requirement), specifies a minimum flow required at a point on the river, to meet water quality, fish & wildlife, navigation, recreation, downstream or other requirements. Depending on its priority, a flow requirement will be satisfied either before, after or at the same time as other requirements in the system. (The minimum flow is achieved either by restricting upstream withdrawals from the river or by releasing water from upstream reservoirs.) The flow out of the node equals the flow in from upstream, plus demand site (DS) and treatment plant (TP) return flows that come in at that point.
