Abstract:

In this paper two principal areas of environmental concern were investigated. The first is the physical impact of dredging and deposition of solid materials causing turbidity on aquatic organisms of the area, including temporary burial of benthic and epibenthic organisms. The second concern is the impact of chemical contaminants associated with the sediments. Based on the environmental impact assessment, the authority responsible for implementing the dredging project is provided with recommendations and guidelines to alleviate serious environmental impacts. Identification of sensitive periods of growth of marine flora, fauna, and fishes in order to schedule project activities out of these periods; and identification of the locations of environmental significance such as nursery and breeding grounds for fish and shrimps or those rich in flora and fauna to be excluded as a candidate dumping site were important recommendations of the study.
