Can someone tell me what influence an angled wall has on the flow over a triangular weir compared to a "normal" vertical one if the wall is angled against the upstream as in the picture?

I would think that at high flow rates the flow over an angled weir would tend to push more water over the weir. At lower rates there would be no difference. I imagine you owuld need to determine this emperically if this were the only way to build your weir.

$\begingroup$ As one of the references I gave points out that the angle of the notch affects how the water sticks to, or separates from, the notch then that causes errors - and the reference point out that they can be large. So not so sure about your "no difference"... $\endgroup$ Commented Dec 1, 2022 at 7:00
