The environmental demand node can be set up as an in-stream requirement (as , where the node acts as a minimum flow requirement node. This ensures that there is sufficient flow to meet environmental demands further downstream. In the example shown in Figure 1). In such a scenario, the node acts a minimum flow requirement nodeIn-stream environmental requirement node ensures that there is adequate flow to fulfill the orders, ultimately, of Water user 9 and Irrigator.
