Development and Future of Dredging
Publication: Journal of the Waterways, Harbors and Coastal Engineering Division
Volume 100, Issue 2
Abstract
Dredging is performed to remove material from the bottom of a body of water to increase its depth or to gain this material. This paper helps develop a better understanding of dredging by describing its tools. Dredges are mechanical or hydraulic in operation, with each category divided into several types. They evolved slowly but experienced a vast increase in size, diversification, and specialization in the last 20 years due to changes in dredging conditions and requirements. The latter essentially result from ecological acceptance, increased transport distances, and extending dredging to assignments heretofore considered impractical. The paper concludes that recent dredge specialization and pollution constraints require careful dredge selection to result in ecologically acceptable economical operation. While economy was the overriding criterion in the past, ecological acceptance is gaining in importance. Means to evaluate and balance these often opposing criteria must be found.
