Kings Bay Upper Basin Remedial Measures; Physical Model Study

摘要

A hybrid modeling system (coupled physical and numerical models) was developed toinvestigate the hydrodynamic and sedimentation processes of Cumberland Sound and the interior Kings Bay navigation channel. This report presents the results of physical model tests conducted to evaluate the effects of nine remedial measure plans on hydrodynamic conditions. These model data were also used to provide average boundary forcing conditions for the numerical model study conducted to determine the impact of the various plans on sedimentation in the Kings Bay basin and adjacent navigation channels. Generally, each of the nine plans had very little impact on base conditions downstream from Kings Bay. However, tidal heights and currents in Kings Bay and the immediate area were altered considerably by each plan investigated. Tests determine the impact of the various plans on base condition salinities were not conducted during this study. A study was conducted to determine the repeatability of tidal heights and current velocities in the physical model. The results of a statistical analysis of middepth current velocity data from 12 locations throughout the estuary are included in this report. (jhd)
