Abstract:

This report describes a numerical modeling study of waves, currents, and sediment transport at Braddock Bay, New York, which are affecting the wetlands in this estuary. The wetlands have had damage by waves that penetrate deep into the bay from the Lake Ontario side. The purpose of this study was to investigate three proposed alternatives using different structural systems at the entrance of Braddock Bay to minimize the impacts of environmental forces on wetlands. Braddock Bay has had steady erosion and retreat of the shorelines outside and within the bay system in the last century. The bay complex in the present state has become fully exposed directly to the winds and waves from the lake side. The proposed structural alternatives at the bay entrance were evaluated on their ability to reduce potential impacts of waves and currents on wetlands. Study results indicated all three proposed alternatives were able to reduce waves, currents, and sediment transport substantially in the bay. The primary goal of the study was to develop a quantitative estimate of waves and flow in the bay for a relative comparison of the alternatives investigated.
