DEVELOPMENT OF NAVIGATION WITH LOCKS AND DAMS
The need for locks and dams for the development of navigation on some streams and the problems that could be encountered are discussed in this report. Satisfactory navigation conditions depend on the site selected, characteristics of the stream, orientation and arrangement of the structure and related facilities, and type of traffic anticipated. Tows approaching the locks could be affected by adverse currents that could be hazardous or cause delays. The lock arrangement should consider the currents to be caused by the completed structure and the effects of these currents on the movement of tows. Model studies can be invaluable in determining the adequacy of a proposed structure and modifications required to eliminate any undesirable conditions. New concepts in lock arrangements should be considered to improve safety and efficiency. Shoaling in the lock approaches can present serious problems but can be eliminated or minimized with special structure. Cofferdam plane should consider maintenance of navigation during construction and the effect of scour on its stability. Deflectors can be used to move the scour area away from the main cofferdam.
