Hello everyone! I've been trying to solve this problem for several weeks...

I was reading in the forum and tried all the solutions proposed for the same problem and I did not get good results.

The water level calculated by the program in the vicinity of the downstream boundary is a few meters different from that indicated by the rating curve.

I use upstream an Open boundary with prescribed Q (455) and downstream I use an Open boundary with prescribed Q and H (555).

I send the .cas file that I use (Parana.cas) and the file of upstream and downstream boundary conditions (hydrographs_Parana.liq and rating_curve.txt).

thank you very much :)

Flor	Thank you!! I'm going to try that!! Another question! In the file rating_curve.txt it is well to put in the first column the discharge [Q(1)] and in the second the water level [Z(1)].
