This report documents the laboratory model investigation of the lock filling and emptying system for lock addition planned for the Marmet Navigation Project. This project is located on the Kanawha River in the U.S. Army Engineer District, Huntington. The filling and emptying system consists of an innovative through-the-sill intake and in-chamber longitudinal culverts. This system is less expensive than the conventional side port filling and emptying system. The model results revealed that the flow conditions in the upper approach during filling operations could be improved by lowering the upstream maintenance sill and streamlining the approach to the intakes. The original design filling and emptying system was found to perform satisfactorily for the design lift of 7.315 m (24 ft) and a 4-min valve operation. No excessive surface turbulence occurred in the chamber, and the maximum hawser forces experienced by a three- by four-barge arrangement moored inside the chamber were considered acceptable. No changes were made to the discharge outlet design.

“Imagonna” takes readers to Africa with a young man in his twenties who is West Virginia's first Peace Corps volunteer. Julian Martin taught chemistry and coached the track team at a secondary school in Nigeria where he was confronted with unexpected racism. You will take a third class train trip with him, be there as he faces into an automatic rifle and as he flees from a man weilding a machete. You will be surprised at who he brings home. The author is the eighth generation of his family born in West Virginia's Big Coal River Valley. He has a chemical engineering degree from West Virginia University and worked two years in the chemical industry. After one month training to make sidewinder missiles, he joined the Peace Corps. Since the Peace Corps Julian Martin worked as Foreign Student Adviser at West Virginia University, taught high school chemistry and physics in the San Francisco Bay area and in West Virginia, directed Urban Outreach for the Charleston, WV, YMCA, and was an organic farmer on his family homeplace. The author is on the board of directors of the West Virginia Highlands Conservancy, the Kanawha State Forest Foundation, the West Virginia Labor History Association and the West Virginia Environmental Education Association. In retirement, Julian Martin is active in the efforts to stop the destructive practice of mountain top removal strip mining in his beloved Appalachian Mountains.

Practical Ship Hydrodynamics provides a comprehensive overview of hydrodynamic experimental and numerical methods for ship resistance and propulsion, maneuvering, seakeeping and vibration. Beginning with an overview of problems and approaches, including the basics of modeling and full scale testing, expert author Volker Bertram introduces the marine applications of computational fluid dynamics and boundary element methods. Expanded and updated, this new edition includes: Otherwise disparate information on the factors affecting ship hydrodynamics, combined to provide one practical, go-to resource. Full coverage of new developments in computational methods and model testing techniques relating to marine design and development. New chapters on hydrodynamic aspects of ship vibrations and hydrodynamic options for fuel efficiency, and increased coverage of simple design estimates of hydrodynamic quantities such as resistance and wake fraction. With a strong focus on essential background for real-life modeling, this book is an ideal reference for practicing naval architects and graduate students.
