Hello,
Hec-Ras seems to have a serious problem to reproduce the flow that crosses a fully opened gate in a straight constant-section channel : important pressure losses appear at the location of the inline structure + gate, whereas there is no modification of the channel cross-section geometry at this particular location. The gate geometric properties are strictly identical to the channel ones. How to remediate to this issue ? Which seems to be a basic issue…
Thanks a lot,
Aurélien B.
