Lateral Force on Aerial Sewer Line
Lateral Force on Aerial Sewer Line
(OP)
I am designing a sewer outfall line that crosses a stream just downstream of a dam. I plan to support the sewer line on steel piers, and will use rigid restrained joint ductile iron pipe. I need help on determining the lateral forces acting on the piers and sewer line resulting from flowing water. Worst case senario would be in the event of a breach of the dam. I expect the forces will depend on the flow velocity and unit weight of the water. I don't need help on determining the dam breach flood wave, just a formula or methodology to determine the forces acting on the piers and sewer line once the flow velocity is determined. Thanks for any help.

It will also model the dam break scenario. May take some learning though if you haven't used it before.

HEC-RAS does a lot more than calculate water surface profiles. It also calculates forces on piers and can estimate scour, sediment transport and model dam breaks. If you've never used it go ahead and download it and look at what it can do. I don't know any other program that can do as much for free.
