Book Description
A real-time ship simulation investigation of the proposed designs for deepening and narrowing the navigation channel for Grand Haven Harbor, Michigan, was conducted. The purpose of the study was to determine if the navigation channel could be deepened from 21 to 27 ft and narrowed from the existing 300 ft to 225 ft and maintain adequate safety. A numerical model of the existing channel from Lake Michigan to the supper limit of the maintained channel was developed. The numerically generated currents were validated independently by two test pilots from the study area since no recorded current velocities exist. They independently reached the same conclusion that the currents should be approximately 1.1 mph. The pilots tested the existing 300-ft channel and two different 225-ft channel proposals. Testing was performed on the U.S. Army Engineer Waterways Experiment Station Ship simulator. These tests demonstrated that either of the 225-ft channel proposals would be acceptable at a 27-ft depth the channel through the jetties should be centered between the jetties, and range markers should be provided.

Ship Navigation Simulation Study, Jacksonville Harbor, St. Johns River, Florida; Volume 1: Main Text and Appendix A.

Pages : 0
Book Description
The ship simulation study of St. Johns River, Jacksonville, Florida, included channel reaches from the outer entrance channel at the sea buoy to downtown Jacksonville, approximately 30 nautical miles. The study was performed to determine the effects of deepening the navigation channel from -38 ft msl to 42 ft msl. The proposed dredging would maintain the existing bank lines and bank slopes, extending the existing bank slope down to the deeper channel bottom, effectively reducing the channel width from 24 to 40 ft dependent on the bank slope. The initial plans examined were to deepen the entire channel without any widening and to deepen and widen the entire channeL Preliminary investigations conducted with pilots from the St Johns Pilots Association indicated that the unwidened channel would not seriously impact navigation, except for two away traffic. A third plan was developed that widened and deepened the channel reaches east of the Dames Point Bridge and only deepened the reaches west of the bridge, along with some realignments of reaches both east and west of the bridge. This plan, Plan C, was found to provide generally improved navigation as compared with the existing conditions.
