Thank you for the explaination. I do have another question. I have taken the time to draw out each reach on paper showing the inlet and outlet depths. I then took the flow depths from each reach report and added them to the inlet and outlet elevations to get the water elevations for each reach...
Thanks for the reply. You lost me when you said making a reach wider will increase the tailwater effect on the next reach. Could you explain that since you said that reaches are not tailwater sensitive?
I have a 440 acre watershed that I have broken up into 5 subcatchments. Each subcatchment reports to a reach, and all reaches are connected in series. I am attempting to model a long trapezoidal drainage ditch (8880 feet) to take the stormwater runoff out of the system. There is quite a bit of...
Would there be any benefit to modeling the entire 257 acre area as one subcatchment, and then including the ditch as a flow segment within? Or would I find more accurate results using the method described previously?
Hello,
I am currently designing a stormwater retention system for a 257 acre surface mining area. I have to provide adequate capacity to contain a 25 year event (8.5 inches in 24 hours). I have the ability to construct a drainage ditch around the perimeter of the mining area which would route...
