Port
Everglades Inlet, Florida
Coastal Systems International, Inc. created a
regional sediment budget as part of a long-term comprehensive
inlet management plan for Port Everglades Inlet. Due to
its location south of the Inlet, John U. Lloyd State Park
experiences severe erosion. The Inlet, however, acts as
a littoral barrier to the beaches residing north of it
resulting in extreme accretion at these locations. Thorough
investigations were conducted including bathymetric surveys
and numerical modeling of current/wave interaction in
order to develop a sediment budget that achieved 100%
sand bypassing to nourish the John U. Lloyd beach.
Coastal
Systems evaluated three conceptual alternatives for sand
bypassing across Port Everglades Inlet to nourish the
beach at John U. Lloyd State Park. The alternatives were
selected based on the results of engineering, economic,
and efficiency evaluations for the sand bypassing alternatives
discussed in the 1994 Port Everglades Inlet Management
Plan. The three selected alternatives were evaluated to
account for an updated regional sediment budget, man-made
activities that contribute to increased sand bypassing
at Hillsboro Inlet, and the projected influences of the
proposed Broward County Segments II and III beach nourishment
projects. An economic analysis was conducted to determine
the amortized annual cost over a 50 year project life
for each alternative to provide criteria for selecting
the optimum sand bypassing alternative.
