Subject:    What are the  Equations  for  Weirs  in  SWMM   5 ,  Part   2 ? There are four types of  Weirs  in  SWMM   5 :  Transverse, Sideflow, V Notch and Trapezoidal.   The trapezoidal weir is a combination of the Sideflow and V Notch Weir and the Sideflow acts like a Transverse Weir when the flow is reversed (Figure 1).  The  Weirs  can have zero, one or two end contractions (Figure  2 ) and the Weir Length is a function of the Weir Setting and Horizontal Weir Length.  A V Notch weir works as Trapezoidal Weir when the Weir RTC Setting is less than 1.0 Figure 1.    Weir  Equations  in  SWMM   5 Figure  2 .    Valid Number of End Contractions Figure 3.   Weir Length Calculations
