Abstract

In order to identify the natural profile conditions for the Delray Beach and Pompano Beach post-restoration project areas, pre-restoration and adjacent native beach profile data for southern Palm Beach County and northern Broward County has been analyzed. Southern Palm Beach County profiles were found to be consistent with previous equilibrium studies. Broward County profiles north and south of the Pompano Beach restoration project were found to be inconsistent with previous studies as well as southern Palm Beach County profiles. This results from the presence in Broward County of a natural shore-parallel coquina ridge formation within the nearshore zone. The profile of the unconsolidated sediments between the beach and the ridge were also analyzed. This region demonstrates a semblance of an equilibrium profile.

With the above findings as a basis, analysis of the process of equilibrium profile reformation 1n the restoration and renourishment projects of Delray Beach and Pompano Beach was conducted. Following the initial project in Delray Beach in 1973, a profile of equilibrium which was consistent with the adjacent south Palm Beach County profile developed in seven years. The equilibrium profile reformation following the initial Pompano Beach restoration redeveloped within one year, inside the coquina ridge formation. This ridge was found to perch the native and renourished profiles of central Broward County and reduce the offshore transport of beach sediments.
