Error No 16

Hi,

I have given boundary conditions: Inflow, Water Level and Q-H. But it is giving Error No. 16 while running the model. I have defined the same name in cross-section and .nwk11 files. 

Error No: In the boundary file, a water level boundary is defined in
                R5: 1526.960 meter. This location is not specified
                as an open boundary in the model setup.

Please help.

Hi suruchigeo,

The problem is that the boundary you specified in bnd11 file is defined as Open for chainage 1526.960 and this point is not actually at the most upstream part or most downstream part of your branch(river). In fact, you can have maximum two open boundary conditions for a branch.

If you describe more detailed what you want to do, maybe we can give you a more detailed solution. Until then, I suggest you to use in the upstream part of your river(branch) Inflow discharge and in the downstream part Q-H relationship if you don't know the variation in time of the water level at that specific point. If your river ends up in sea or in a lake, you can probably use WL open boundary condition (as constant or as a time series), or in any other cases when you know the water level at the downstream location.
