Natural fluctuations in nearshore turbidity and the relative influences of beach renourishment

Turbidity is a measure of the clarity of water. Turbidity depends upon thescattering and absorption of light by suspended particles. The focus of this study wasto obtain quantitative measurements of turbidity in the nearshore zone, along withmeasurements of associated wave parameters and currents occurring naturally andduring a beach nourishment project. The objectives were to make quantitative andqualitative comparisons between natural events and those induced by the dredge andfill operations, as well as assess the long term effects of the nourishment, uponturbidity.In-situ measurements of turbidity and wave climate were obtained at two shorenormal sites off the coast of Hollywood, Florida, from January, 1990 to April, 1992.The beaches adjacent to the communities of Hallandale and Hollywood wererenourished during the summer of 1991. Thirty minute in-situ observations wererecorded in burst mode every four hours at a frequency of four hertz. Analysis of thedata resulted in descriptions of the wave climate as well as statistics of turbidity for each observation.
