Dredging Index for Sediments Remediation Management
Abstract:Dredging of contaminated sediments is one option often considered for remediation in coastal waters. There is a need to determine hot spots, areas of concern, and unpolluted areas in order to prioritize dredging operations. A dredging index was developed for this purpose by combining four different numerical sets of sediment quality guidelines into a quadrodiagram. The constructed quadrodiagram gives graphical information about sediment quality, whereas the dredging index provides a quantitative assessment of the degree of sediment quality degradation. Sediment quality data from a number of studied areas was compared in terms of the dredging index and was capable of distinguishing heavily impacted regions from lightly or nonimpacted regions.
