The discharge capacity of a side weir is significantly less than that of a weir with a crest perpendicular to the main flow ... Total flow over trapezoidal weirs with side slopes is computed using the standard weir equation as shown above, plus two times the flow given from the following equation. Where: Q = discharge over side-sloped portion of weir, cfs (cms) Z = side slope (Z horizontal to 1 vertical) of the weir crest H = distance … See more V-notch weirs are computed using this equation: Where: Q = discharge over weir, cfs (cms) Θ = angle of v-notch in degrees H = head on apex of v-notch, ft (m) See more Weirs can be affected by submergence, i.e., when the user-inputted tailwater rises above the weir’s crest. The equation for the reduction in flow is: Where: Qs = submerged flow, cfs … See more
