Error: "The static head cannot exceed the maximum pumping depth, i.e. 0.0 meter"

[Amr Ibrahim]

Project design -> Pumping -> User's needs -> Pumping System Type: Lake or River to Storage

After I insert all the required data, I get the following error no matter what values I insert in "Lake/river water depth - Yearly constant" and "Pump depth":

"The static head cannot exceed the maximum pumping depth, i.e. 0.0 meter"

Why am I getting that error? And how can I solve it?

Thanks a lot.

This is indeed an error: this verification doesn't apply to the "Lake or River" configuration.

This will be corrected in the next version 6.53.

In the meantime, there is a workaround: in the "Hydraulic Pumping circuit" definitions, you should choose for Pumping system type "Deep well to storage", modify the parameter "Max. pumping depth" to a high value, and come back to your "Lake or River to Storage" option.
