It is a simple 1-D model, steady state.
The model has no problem and removing piers doesn’t answer my question.
Here is the hand calcs:
Skewed weir width = W x Cos(20)+L x Sin (20)=1.5 x 0.94 + 55 x 0.34 = 20.11
w=width of pier
L = length of pier which is the same as bridge width

I have 4 piers and the total skewed pier width is about 88′. This length obstruct about 80% of my flow conveyance. The model shows almost the same thing. The question is that is this realistic? Should I not skew the piers

Cameron,
Thank you very much for your quick reply. Sorry that I didn’t remove that extra words from my shared file. But, removing those doesn’t help me. Do you have another solution?

Thanks
