Weir with end contraction (contracted weir) Weir without end contraction (suppressed weir) Classification Based on Shape of Opening Rectangular weir: It is a standard shape of weir. The top edge of weir may be sharp crested or narrow ... WebWeirs in an outlet of a detention pond can be treated as one of the control elements in the composite outlet control structure. Another example of a side weir is the emergency overflow weir or spillway at the top of a detention pond. Side weirs are only used to model flow splits in the implicit or explicit solvers.
