MIKE11 user defined function for structure

Hello,

I need help to calculate terms of momentum coefficient for a case of discharge through a gate which pertinent to change of water level at upstream. (e.g. 20.2<H_up<22.5 , Q=4.329 H_up +2.125)
I read the MIKE_Reference but it makes me confuse.
Also, could you let me know the steps of making dll file?

Thanks
 

Hello Ella,
There are a couple of options for doing this. The easiest is to utilize the controle structure using a discharge gate with the operation described through a table.
