Twelve Navy harbors in the Continental U.S. require maintenance dredging in excess of 0.1 M cu yd per year. They account for 78% of the Navy's annual 9M cu yd total. Two thirds of the area dredged is located within quiet water berths, typically formed between rows of pile piers. About 87% of the material dredged is mud (silty clay or clayey silt) deposited by estuarine processes. (Author).

This collection contains 120 papers presented at Dredging '84, held in Clearwater Beach, Florida, November 14-16, 1984.

With today's problems surrounding shoreline protection, this book should be of great assistance. This manual contains a compilation of 2 Navy and 2 Corps manuals all relative to the subject of coastal protection and the affects tidal action has on our shorelines. The titles included are: Coastal Protection is a U.S. Navy publication which deals specifically with waves and their characteristics. In order to prepare safe designs, the normal and extreme waves which will act against the structure must be evaluated so that a design wave can be selected. Pilebuck takes the user through this phase into the application of data to actual design of breakwaters and seawalls. Storm Surge Analysis: High tides and wind-generated waves combine to provide a potential for abnormally high water levels and flooding during hurricanes or other serious storms. An understanding of this phenomena is essential in order to plan control structures or design others.
