THEORY AND PRACTICE OF WATER INJECTION DREDGING
In terms of cost, water injection dredging can often be compared very favorably with conventional dredging methods, since the dredged material is transported by a naturally occurring density current--a result of differences in density between, on the one hand, a mixture of water and sediment and, on the other, water. Jet penetration, jet dispersal, density flow and sedimentation play an important role in this type of dredging process. These have been explored with the aid of theoretical research, scale model tests and in situ measurements. Some of these results are described. The water injection dredging theory has been put into practice using the water injection vessel JETSED, and some of the working methods employed are briefly considered. A number of case studies illustrate the capacity and capabilities of the JETSED.
