Not sure if my brain hasn't started working or what (I just got back from vacation)....
How can I determine what size detention basin I need with a calculated Qin and a specified Qout using the rational method. I can do it using TR55, but all my other calcs are based on rational so I'd rather not switch back and forth.
i.e. I have detention basin with ~25 cfs coming into it and I want to limit the discharge to, let's say 10 cfs irregardless of what the governing body's requirements are (the basin is going to be on a ridge so really there is no predeveloped runoff).
