uplift on spillway chute

[cvg]

I am designing a spillway chute and calculating the forces which will be applied to the slab. The chute is uniform width, straight and is to be constructed with a straight grade without any grade breaks or vertical curves. Will there be any substantial hydrodynamic uplift or down forces due to the high velocity? I am looking for references with theory / equations.

I suggest "Design Of Small Dams" U.S. Bureau of Reclamation as the start. If the information in it is not sufficient, it has excellent references.

The maximum hydrodynamic uplift will be limited to vaccum.

Hope this helps.
