Abstract

The results showed that structural effects on crosscurrents at the entrance were effective when even length jetties were used. Non structural changes (deepening the inlet at jetty ends) further reduced the magnitude of currents. The U.S. Army Engineer District, Jacksonville (SAJ), is evaluating jetty modification plans at the entrance channel to alleviate problems with strong crosscurrents at the ocean entrance and inner harbor channels to Miami Harbor. The U.S. Army Engineer Waterways Experiment Station (WES), Coastal Engineering Research Center (CERC), was requested by SAJ to conduct a tidal circulation numerical model study, to quantify the problem better, and to evaluate remedies.

CERC applied the WES Implicit Flooding Model (WIFM) along with a companion prototype data collection study in the Miami area. The field data required for the numerical model calibration and verification were collected by the National Oceanic and Atmospheric Administration (NOAA) and WES.

The numerical modeling approach consisted of applying WIFM in a two-phase modeling study. The first phase involved a global model which included areas of the inner harbor and a substantial open ocean area with a 200- to 300-ft minimum grid cell dimension. This model was calibrated against neap tidal events and was verified against spring tidal events using observed data.

The second phase of the modeling effort involved a fine resolution grid (minimum grid dimension 100 ft) 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 paper focuses on the use of the refined numerical model to evaluate the tidal current regime at the entrance to the Port of Miami, and to access the impact of proposed structural (jetty extensions) and nonstructural modification plans for reducing strong crosscurrent effects on navigation.
