Best method to use to size detention basin...
(OP)
I used hydrocad about 3 or 4 years ago but I can't remember a whole lot about it. I have a site where I need to size a detention basin to store the 25 year post developed discharge and let it out at the 10 year pre developed rate.
I have entered my area and time of concentration values in my subcat for the predeveloped. What is the best way to come up with the required size of my basin and weir? I have a copy of a project another engineer did and he used the Custom Stage Data method. Is this the method I should use?
Thanks for the help.

RE: Best method to use to size detention basin...
HydroCAD provides a pond sizing report that will estimate the amount of storage required to attenuate your post-development peak flow down to the target rate, such as the pre-development flow.
Basically, setup the model for the proposed condition, with your flows routed to a new (proposed) pond. The pond does not have to have any data at this point - just route the flows there. Now right-click the pond and open a report window. Select the Sizing tab to see the pond sizing report.
