Flood Wall Design
Flood Wall Design
(OP)
Hello everyone,
Have you ever designed/ or have some tips on Flood wall design?
The condition is :
-NON-COASTAL FLOOD WALL
-CONCRETE
-APPROX. 10'-0" FLOOD WATER HEIGHT
-1'-0" FREEBOARD
ASCE-7 States as:
-Can be treated as retaining wall with additional consideration to the following
-Hydrostatic pressure
-Hydrodynamic pressure
-Impact load (from derbis and others transported by flood)
-Uplift Pressure
-
-
Please advise me if you have any experience on this.
I googled about Flood wall but i couldn't find much.
Your response is appreciated!

Be forewarned, I'm presently using this for the first time and you wouldn't believe the hours I've spent in attempting to understand the methods it provides for floodwall design. But maybe that's just me.
Good luck.

Obviously you would design for 11' (approx) water height

Thanks Jack for your link to Corps Engineers's documents
Thank you all for sending me some tips
I was trying to approach this according to ASCE-7/98
- My concern remains on the issues of hydrodynamic loading
(how to find velocity of water, v)
dh=(aV2)/2g
-The Code suggests you can calculate avelocity head 'dh'
with the emperical formula and add it with the design flood height and treat it as an equivalent electrostatic load with (H=hflood +hd)
Any approach to estimate flood velocity.?
Thanks

RE: Flood Wall Design
'Electrostatic pressure' is an error
i meant .. 'hydrostatic pressure' with
(p=gamma water * Hequivalent)
sorry about the error.
