Dispersion Wall

Dispersion Wall

Dispersion Wall

(OP)
Can anyone provide me with a reference for dispersion walls, which take concentrated flow and converts it to sheet flow.

Thanks

RE: Dispersion Wall

I have also heard these referred to as "level spreaders".  Don't know of any real references, but it might help in your search.

RE: Dispersion Wall

Lots of cities and states have specifications or design minima in their drainage ordinances.  

Level spreaders work best on slopes flatter than 10% with flows less than 30 cfs.  Level spreaders should not be constructed in fill slopes. Some agencies will let you get away with a non-erosive velocity passing over the level spreader lip.  Others take a more conservative view.  (Briefly, flow reconcentrates within a distance, L, of the level spreader, where L is a function of the slope.  Some agencies require a flow depth over the level spreader that results in a non-erosive velocity at a distance L/3(?) downstream of the level spreader where the flow has started to reconcentrate.)
