hydrology-Time of concentration for large watersheds
(OP)
I have used Kirpich formula for calculating the time of concentration for small watersheds,however for large watersheds it is giving conservative results"shorter duration " compared to other methods as the Kinematic wave equation which is developed by the University of Maryland & is recommended by Federal Highway Administration for overland flow.
my question can we use the wave equation to calculate the time of concentration for large watersheds(10sq miles or larger)
my question can we use the wave equation to calculate the time of concentration for large watersheds(10sq miles or larger)

Unless one has a long record of flows at a bridge site, it is probably not wise to trust anecdotal evidence. Just knownig that a bridge has not been overtopped in recent years wouldn't tell you very much unless you can relate flows, water surface elevations and probability of recuurance over a significant period of time.
good luck
