Hello, so my case is I don’t have a dam bathymetry data, however I have approximate dam area and dam volume. I consulted my professor and he instructed me to compute dam releases by an equation for gate discharge and just estimate the time duration of water level drainage. Now my question is, how long will be a typical dam release duration?
It depends on the dam, how much water is in the reservoir, how much water is anticipated to come to the reservoir, impacts of release downstream, and other things. Most dams have operating guidelines specific to that dam.
