DREDGING - BUILDING AND MAINTAINING OUR UNDERWATER HIGHWAYS
The water transportation system, operating since the early 1800s, has played a major role in the growth of the United States' economy. Today this system serves as the pillar to one of the most extensive and economically significant waterborne commerce operations in the world. Over the years the size of ships has gotten significantly larger. With their increased size, ships need improved navigation channels to enter and leave ports efficiently, quickly, and safely. Periodic maintenance dredging as well as occasional enlarging and deepening of navigation channels is essential to accommodate commercial and recreational vessels. Consumer product prices stay low when ships can transport their goods directly into the port. In addition to the aforementioned concepts, the publication briefly discusses the history of dredging, and also notes different types of dredging equipment. Methods of moving dreged material are described, and the benefits of dredging to the environment are noted.
