Tailwater level for turbines and weirs
A Tailwater level is supplied by a control-function (system status). The ID of the desired control-funtcion must be named in the column WSP unten. The IDs of the control-functions are assigned in the KTR-File.
If no tailwater level is supplied, the tailwaterlevel will be determined as a MIN_mNN, which is a constant with the value -490 müNN.
Lowerable weir
A lowerable weir can be implemented by writing the ID of a control-function (refer to KTR-File) into the column Fak hue. The value/factor from the control-function will be subtracted from the normal weir crest for each time increment (not multiplied).
