I am doing a side weir design using equation of the book Hydraulic design of side weirs by Richard May . Mr. May used the exponent of 3/2. Then I modeled the side weir in SWMM the spill flow values that I got was not the same as I computed.When I check the equations results that SWMM use the head exponent of 5/3.
WebZ = side slope (Z horizontal to 1 vertical) of the weir crest H = distance between water surface and the crest, ft (m) Cw = weir coefficient, typically 3.367 (1.83) Cipolletti weirs have .25 H to 1 V side slopes, Z = 0.25. V … Web6 okt. 2024 · Whilst the definition focuses on the weir’s ability to raise the water level on the upstream side of the weir, it’s what happens on the downstream side that is normally of more concern to us. As water flows over the face of the weir there is the potential to create a ‘re-circulation’ feature on the downstream side when surface water is pulled back into …
