Subject: WEAP API automate gw node where transmission link loses water to Posted: 3/3/2022 Viewed: 5621 times
Using the WEAP API through Python:
Is there a way I can automate setting the gw node the transmission link loses water to? I am able to automatically set the percentage like e.g. in 10% in the example below. However, how can I set the “to Groundwater” node the transmission link loses water to? Or is this not possible?
self.WEAP.Branch('Supply and Resources\Transmission Links\to AI_11\from Withdrawal Node 5').Variables('Loss to Groundwater').Expression = 10

This is currently no way using the WEAP API to set or change which groundwater node is linked to a reach. I hope to add this capability in a future version of WEAP.

To provide an update, we have since enhanced WEAP to now be able to link groundwater objects to river reaches using API. The latest versions of WEAP have a function for "ConnectedGroundwater". Please see the WEAP Help for "Branch API" and scroll down to ConnectedGroundwater. The help gives the following examples:
' List all nodes or reaches that have connections to groundwater
FOR EACH Br IN WEAP.Branches
SET GWNode = Br.ConnectedGroundwater
IF GWNode.ID > 0 THEN
PRINT Br.FullName & " IS CONNECTED TO " & GWNode.Fullname
END IF
NEXT
' Connect Central Reservoir to North Aquifer
WEAP.Branch("Central Reservoir").ConnectedGroundwater = "North Aquifer"
' Connect Central Reservoir to the first groundwater node
WEAP.Branch("Central Reservoir").ConnectedGroundwater = WEAP.GroundwaterNodes(1)
' Remove GW connection from Central Reservoir
WEAP.Branch("Central Reservoir").ConnectedGroundwater = ""
