how to model broadcrest trapezoidal weir in hydrocad
(OP)
need help modeling a broadcrested trapezoidal weir typical in dam emergency spillway designs. I use to run Dams2 for these and checked a hydrocad run against and old design. Upon comparison, i realized the emergency spillway calcs are not accounting for my sideslopes along centerline of the dam. Maybe Mr. Smart can help me out.
Thanks in advance.

To handle your weir with side slopes, use the Vee/Trapezoidal weir option.

In my experience, even modest chamges in the rating curve usually have a minimal effect on the final hydrograph routing. Of course, this depends on the exact situation, so I urge you to try both solutions and compare the results yourself.
