||Erosion of downdrift beaches Is a problem commonly associated with most tidal inlets. Thus, it is undoubtedly a major consideration when pursuing an effective tidal inlet management plan. Various sand bypassing simulations at Jupiter Inlet, Florida, were examined through the use of synthetic longshore transport rates generated from wind hindcast was data in incorporation with local sediment budgets. In order to determine whether sand from the downdrift beach was infiltrating around the south jetty and into the inlet during flood tide, a sand tracer study was conducted three different times over a one year period. Similarly, sediment transport patterns pertaining to the downdrift beach o Jupiter Inlet were also investigated throughout the use of a drogue study performed in a physical model located at the Coastal and Oceanographic Laboratory at the University of Florida. Finally, in an attempt to determine the most optimal jetty configuration at Jupiter Inlet, different jetty modifications were implemented into the drogue study. It was found that annual renourishment of the downdrift beach at Jupiter Inlet before the specified nonpumping window would be most beneficial. By renourishing the downdrift beach in early March, a larger beach would be present throughout the summer, aiding nesting turtle s and appealing to summer vacationers. It was also determined that the jetty adjacent to the downdrift beach at Jupiter Inlet was indeed “leaking” (and was migrating from the downdrift beach, around the downdrift jetty, and into the inlet). Traces of fluorescent colored sand were found inside the inlet on two different occasions, some of the sand remnants of a tracer experiment conducted eight months prior. Finally, it was concluded that the optimal jetty configuration s it concerns the downdrift beach would involve either an extension of the north jetty with a downdrift curvature or an arm-like attachment to the south jetty which would extend southward with the goal being to create a larger “shadow-zone” downdrift of Jupiter Inlet.
