Abstract: The Palm Beach Harbor Navigation Project Management Plan (PMP) outlines a plan for identifying solutions for improving the navigation in federally maintained channels in the northern area of Lake Worth. Two critical elements, identified in the plan, for reaching that goal are the currents within the channels associated with each alternative and estimating project induced channel shoaling rates. The objectives of the hydrodynamic modeling were as follows: 1) To provide the hydrodynamic inputs for use in the Ship Simulation Model. In order to meet this objective, a two-dimensional hydrodynamic model was developed that is capable of simulating complex flows in a large model domain. A two-dimensional hydrodynamic model was considered appropriate for comparison of current magnitude and direction between alternatives since the Lake Worth Lagoon is a well mixed estuary and the currents are primarily driven by tidal forcing. Also the Ship Simulator Model requires two-dimensional, depth averaged, currents and can not utilize three-dimensional currents. 2) To assess changes to circulation and shoaling patterns resulting from proposed channel geometry deepening modifications. The settling basin to the north of the entrance channel is an integral part of the sediment transport dynamics in the entrance channel area. The settling basin has been expanded several times to reduce shoaling in the entrance channel. Included in this investigation is an evaluation of the present and proposed settling basin as well as recommended modification for greater reduction of shoaling in the navigation channel. Evaluation of scour and hydrodynamic forces of the north jetty stabilization sheetpile wall would require a finer scale hydrodynamic model are not included in this modeling effort.
