Hello, I work in scenarios about dams and I want to import points about volume-elevation curve. I have the heights of the water measured from the start of the reference system of the country and the heights measured from the start of the dam. Which ones should I use?
Thanks in advance.

For the sake of consistency, it would be preferable to use the elevation data (country reference system). However, WEAP results shouldn't be affected as long as the heights are internally consistent (all use the same reference point).

Dear Anne,
I have a similar question: I am modelling in the Draa Valley in Morocco and I have the NGM values of Morocco and the volume that corresponds to that NGM. Can I use the NGM in WEAP therefore for my elevation [m]?
Thanks!

How to add the data of volume elevation curve in WEAP tools

I'm providing more information on volume elevation curves for reservoirs in WEAP.
The datum you choose for the elevations does not affect the calculations. What matters is that the elevations entered for each row under Volume Elevation Curve all use the same datum. If you are additionally modeling hydropower, then the Tailwater elevation must use the same datum.
To add the Volume Elevation Curve, go to the Reservoir in Data Tree --> Physical --> Volume Elevation Curve. Then, you can enter the storage volume achieved for each elevation of the water surface. If you have a spreadsheet of the data, you can copy and paste it here.
