Does anyone know of any publications that specifically research sediment deposition downstream of culverts or other flow focusing structures to determine how far downstream the effect goes? There are perirheic zones where the water just goes and sits without moving, collecting large organic debris from my observations, but how far until the deposited sediment regains normalicy?
About 4 to 6 times the cross-sectional diameter, downstream the trailing edge of the bridge-pile,...for most of sediments. it's a matter of turbulence wake. Of course dependent upon the drag-coefficient, the type of sediments,...
Dan,
A lot of material on this but you have to do some digging. A lot of it is driven by local processes (as you well know). Few examples:

Dear Daniel E. Kroes
I have worked on culvert designing in MS thesis. I use HEC_RAS for flow and sedimentation analysis. A very brief and informative notes are available at HEC RAS web. I hope this will be useful to use HEC_RAS for concerned problem

Cliff Hupp let me know about this study from the early 90s
Hupp, Cliff R., and David E. Bazemore. "Temporal and spatial patterns of wetland sedimentation, West Tennessee." Journal of Hydrology 141.1 (1993): 179-196.
Good question.. Please share me the best answer might you trust...
