Hello,
I would like to know please, how do we define the position of ineffective flow areas around a bridge ? Could anyone help me please ?
Regards
There is good information on this in the user’s manual. In general, most people use 1:1 contraction upstream and 2:1 or 3:1 expansion downstream from the bridge opening, but it can change depending on the structure.
