full water column and subset of column for Gate Data setting in MIKE21

Hi,
I want to add a gate in the Structures section in MIKE21, could anyone tell me what's the meaning of full water column and subset of column for Gate Data?

I couldn't find such details in the manual or with the help of F1, is there any information (like manual, report, paper) that I can refer to?

Thanks very much.

Regards,
Cathy

Dear Cathy,

Those two options are based on the way you operate the gates. Full water column can be used when you assume the gate is completely open/lifted.
There are two cases where you use subset of column,
[list type=decimal]
[li]when you use a sluice gate or half opened gate [/li]
[li]while using hanging weirs as a blocking gate [/li]
[/list]
