Abstract : The design of barriers for protection of Narragansett Bay against inundation by hurricane surges required use of a comprehensive model to determine the effects of proposed structures on normal tide and hurricane surge heights, current velocities, the salinity regimen of the bay, and the rates of diffusion and flushing of pollutants discharged into the bay. Model tests indicated that barriers should not be located in the central portions of the bay because of excessive buildup of surge heights downstream from such barriers, that a lower bay barrier alone could not satisfy the requirements of the Navy and at the same time afford the desired reductions in surge heights at upstream locations, but that the combination of a gated structure at Fox Point for the protection of Providence with a system of lower bay barriers with ungated openings could satisfy the requirements of the Navy for maximum current velocities and at the same time provide hurricane surge protection throughout the bay system.
