Unfortunately, I rarely have the fall to do what you're talking about (Ohio's super flat), although I really like the idea you are proposing. I'm sure I'll use it in the future.
I understand the routing time will approach infinity, but then how can I possibly meet requirements without using...
I'm in Ohio. Our soils are clay, so no I do not include exfiltration.
Here's my problem with HydroCAD:
Only applies when routing a drainage area into a pond with outlet structure.
I double click the pond to bring up my results, then I pull up the table to see what's actually going on...
Thanks for the suggestions. I've chalked up the problems I was having to limitations of hydrocad. Yes, my initial outlet structure was a water quality orifice with a larger flood control orifice above it. With that setup I wanted to reduce the rate of release at high head and increase the rate...
I'm designing a dry extended detention pond and I'm having difficulty meeting my water quality requirements. What techniques do you use to to decrease the initial drawdown rate and subsequently increase drawdown rate. Basically, I need to reduce the rate the first 50% of my WQv is released and...
