I'm modeling a dam which has multiple rectangular notches in a spillway/ b.c. weir. The flow drops down to an adjacent lower box culvert under the road (which can't handle the 100year flow) and then the water would rise up to and over the road (asymmetrical weir). What's the best HydroCAD way to model this...I've tried multiple ponds, pond & cb-pond, single pond. The low box culvert obviously doesn't flow until the spillway weirs flow at their higher level. Modeling as separate ponds does not result in a single/equal pond elevation, which is reality. Any ideas??
