Abstract : The US Army Engineer District, Jacksonville (CESAJ), is evaluating jetty modification plans at the entrance to the Miami Harbor to alleviate problems with strong cross currents at the ocean entrance and inner harbor channels. The US Army Engineer Waterways Experiment Station's (CEWES's), Coastal Engineering Research Center (CERC), was requested by CESAJ to conduct a tidal circulation numerical model study to better quantify the problem and to evaluate remedies. Discussed herein is the WES Implicit Flooding Model (WIFM), a two-dimensional vertically integrated numerical model, along with a companion prototype data collection study in the Miami area, which CERC applied. The field data required for numerical model calibration and verification were collected by the National Oceanic and Atmospheric Administration (NOAA) and CERC. The numerical modeling approach consisted of applying WIFM in a two-phase modeling study. The first phase involved a global model. This model was calibrated aganist neap tidal events and was verified against spring tidal events using measured data. The second phase of the modeling effort involved the development of a fine resolution grid in the entrance channel and port facility areas. Boundary conditions for this grid were supplied by the global model. This model was calibrated and verified for tidal events using observed data. This report describes the use of the gobal and the refined numerical models to evaluate the tidal current regime at the entrance to the Port of Miami, and to assess the impact of structural (jetty extensions) and nonstructural modification plans for reducing strong cross-current effects on navigation.
