How do you model a underground storage system with multiple chambers that has a flap valve to allow flow in one direction only? The model requires the pond and reach to use storaqe and routing to use dynanic-stor-ind. Thanks for your help!
Outlet devices are automatically assumed to be one-way, as if there were a flap valve on each device. Since the use of a flap valve implies that tailwater is present, you should also use a tailwater-sensitive routing procedure. For details see
