Creating a New Scenario

Please watch the video for additional detail.

Create new scenario and compare with Baseline

Scenarios allow users to explore and evaluate different conditions or management strategies within the water system model.

1. To create a new scenario, click on the Clone a scenario icon.

choose Baseline as the scenario to clone, add a name to your scenario, in this case 'With abstraction', and click Clone.

You will see the new scenario is automatically made active.

At the moment, the new scenario is an exact clone of the baseline scenario.

In this scenario, we will assign a demand to the demand node. Change the max_flow of the demand output node to 5.0 Mm3/day

Run the new scenario and then view the simulated_flow of the demand node.

Now the amount of water supplied is no longer 0. The demand attempts to abstract 5.0 Mm3/day of water. However when there is not enough water in the river the full 5.0 Mm3/day cannot be abstracted.

Lets view the simulated_flow of the sink output node.

Lets compare the river outflow in both scenarios.

Add the baseline scenario to the view by selecting it in the menu and then pressing the Play button

We can see that the less water reaches the outlet in the With abstraction scenario and sometimes there is no water flowing into the outlet.
