In the early days the canal was for shallow draft traffic, much of which was horse drawn. This waterway has grown tremendously in importance. It cuts many hours of sailing time for ocean going vessels between New York, Philadelphia and Baltimore and during both World Wars it was of inestimable value in keeping coastwise traffic moving without exposure to submarine hazards. Increasing traffic and size of vessels using the canal have brought about the need for its enlargement again.dredging spoilenvironmental aspectscanalspoilcoastal constructioncoastal zone managementBook
