Tidal Hydraulics (EM 1110-2-1607), Chapter 5: Design Considerations

This chapter turns the analysis into design. It covers the purpose and types of control works and the design factors that bear on them, such as navigation, salinity, water quality, and channel sedimentation.

It then covers siting of control works, including flooding, estuarine breakwaters and jetties, salinity barriers, hurricane barriers, training dikes, revetments, diversion works, and sediment traps. A section on maintenance dredging covers dredging plant, advance maintenance dredging, and agitation dredging with vertical mixers, air bubblers, rakes, drag beams, and water jets.

It closes with case histories, including lessons learned and physical model studies, so designers can learn from projects that have already been built. The related environmental considerations are covered in a separate chapter on water quality, biology, and dredging effects.
