Gradually Varied Flow - Normal Depth US HW?
Gradually Varied Flow - Normal Depth US HW?
(OP)
Flow Regime: Sub-critical & open surface flow
In a scenario where one needs to do backwater calculations for a channel / culvert in subcritical flow, is assuming normal depth as the US water level acceptable? At some point the backwater calculations will converge to normal depth, but I've never read anywhere where it is acceptable to use the normal depth. I assume this is because it may not converge by the time you hit your next analysis point?
