BRIEF DESCRIPTION OF PROJECT AND RELEVANCE TO THIS CONTRACT (Include scope, size, and cost) <br /> <br />Coastal Systems conducted an analysis of coastal processes at Sunny Isles Beach <br />to provide recommendations for future beach management. Long term and storm- <br />induced beach erosion along the 2.5 miles of City of Sunny Isles Beach requires <br />frequent and costly maintenance with beach nourishment. Beach compatible sand <br />sources in Florida are diminishing, and long term stabilization of hot spot areas <br />and reduction in beach nourishment event frequency overall may be beneficial in <br />maintaining adequate beach width for shore protection and for recreational use. i,~ <br /> <br />Coastal Systems conducted a comprehensive coastal engineering study for Sunny <br />Isles to evaluate coastal processes along the shoreline of Sunny Isles. Detailed <br />hydrographic surveys of two existing submerged breakwaters were conducted <br />along with beach profiling to provide data for input into the numerical modeling <br />software. Offshore wave statistics were prepared utilizing wave data from 1980- <br />1999 to obtain annual conditions that influence sediment transport. <br /> <br /> <br />_,.._>h~ <br />-- . <br />'"'-'lI ........ <br />i~~ <br />_......... <br />!':! ;E.~ <br />Ei ,"0.._ <br /> <br />Wave modeling was conducted by utilizing the Danish Hydraulics Institute (DHI) MIKE 21 Spectral Wave (SW) model <br />to simulate offshore waves propagating onshore. This model was coupled with the MIKE-21 Hydrodynamic (HD) <br />model to determine the littoral current generated by breaking waves. The resulting sediment transport was evaluated <br />to identify erosion trends along the shoreline. The numerical modeling results indicated that the north segment is <br />characterized with the highest degree of erosion, while the south section was mildly erosional, and the middle <br />section was relatively stable. <br /> <br />Two hot spots were identified in the northern section, and wave focusing results were evaluated. Beach management <br />recommendations were prepared based on the coastal engineering results, and coastal structure concepts were <br />prepared for shore stabilization. Additional beach management recommendations were provided as longer term <br />solutions to reduce erosion rates, mitigate local hot spots, and to extend the life of beach nourishment projects. <br /> <br />[ ~~.]~EMil.]~~~ I <br /> (1) FIRM NAME (2) FIRM LOCATION (3) ROLE <br />a. ~ Coastal Systems International, Inc. leoral GableslW est Palm Prime <br /> : " '" - -~ .
