Abstract

This paper discusses evaluation of inlet channels morphologic response to natural evolution and management practices at various navigation inlets in southwest and central Florida. The scope of the evaluation includes the natural evolution of the inlet channel and effects of navigation dredging, as well as mining sand from other parts of shoal systems as sources of material for beach nourishment. This paper reviews three case studies of navigation inlets in southwest and central Florida with various inlet stabilization scenarios. The case studies include an inlet with two long jetties (Venice Inlet), an inlet with one jetty on the up-drift side (Longboat Pass) and an inlet without stabilization structures (Wiggins Pass). Data and model results for each of the three cases are analyzed to understand common factors that contribute to channel migration for inlets with/without jetties and maintenance dredging programs.
