DMS: Diagnostic Modeling System. Report 4: Shoaling Analysis of St. Marys Entrance, Florida

Abstract

This report presents an analysis of the sediment shoaling characteristics of St. Marys Entrance, Florida, performed for the U.S. Army Engineer District, Jacksonville. Shoaling characteristics and alternatives were investigated for the entire inlet entrance channel. Diagnostic Modeling System procedures were applied to determine causes of channel shoaling and evaluate possible mitigation alternatives to reduce the frequency and cost of dredging. Nearshore wave and tidal circulation modeling was conducted to establish patterns of the current in response to channel configuration alternatives and to estimate sediment transport toward the north jetty from the adjacent beach. Morphological analysis based upon bathymetric surveys, combined with modeling results, indicated that eastward extension of the channel widener would increase the time interval between maintenance dredging events.
