Civil/Environmental

I am looking for any materials pertaining to the design of helical dropshafts, aka helicoidal drop structures, helicoidal-ramp inlets, radial flow helicoidal-ramp dropshafts, vortex flow dropstructues etc. I am to design seven for various combined sewer overflows into a deep, nine-foot tunnel. Names and numbers for any professionals with experience in this field would also be greatly appreciated!
