Use the video below to define a monthly releaes rule that represents a minimum environmental flow downstream of the reservoir. You are free to define the monthly flows that you feel are appropriate. Please use a new scenario by cloning the 'Demand with GW scenario'.
Hint: This can be done by defining a monthly parameter on the Max Flow of the release rule. How does the environmental flow affect the simulated volume of the reservoir? How does it affect downstream flows? Please show the plots generated for these output parameters.
Create a new scenario called 'Dry scenario' by cloning the 'Demand with GW scenario'. In this new scenario, update the catchment Flow parameter on the Catchment node to the time series found in column 'Mosetse Dam_1' from the Mosetse Data spreadsheet.
How does this inflow scenario impact reservoir storage? How low should Moseste demand be for the reservoir to not empty without the groundwater and Chobe transfer.
Try out different values of Max Flow on the Mosetse demand node.
Connect the Chobe Zambezi transfer to the Mosetse demand node. How does this affect reservoir performance and the environmental flow downstream of Mosetse reservoir. Please do this excercise by cloning the 'Dry Scenario'.
Try putting a constraint (Max Flow) on the abstraction from the Chobe Zambezi transfer using a Link node. Try constraints of 0.02, 0.04, 0.05. How does this impact the reservoir volume?
