This book contents about waste disposal and dredging activities, shelf sediment dynamics and solid-waste disposal, stability of dredged, geological effects of ocean dumping, depositional characteristics of sediments and problem of misplaced sediment.
Ports are facing increasing environmental concerns with their importance to the global economy. Numerousstudies indicated sediment quality deterioration in ports; however, the deterioration is not discriminated for each port activity. This study investigated a spectrumof contaminants (metals and organic pollutants) in surface sediments at 20 sampling points in Port Ningbo, China, one of the top…
As bays, lagoons and estuaries ensure protection from wind, and a hinterland rich in natural resources is most enticing, during the early Iron Age the seafaring Phoenician settlers chose such locations all over the Mediterranean for their seaports, establishing pan-Mediterranean trade from the late 9th century BCE onwards. Despite the difficult nautical conditions, Phoenician sailors had conque…
In the framework of an ecological risk assessment of seaport sediments for terrestrial ecosystems when deposited in quarries, we simulated the ‘‘ageing’’ of sediments exposed to rain. This experiment highlighted an inflection point at the solid/liquid ratio 1/25, after which the extraction of pollutants increases moderately. The raw sediments studied inhibited the germination of Lolium …
central coast of the São Paulo State, Brazil. Sediment qualitywas evaluated through physicochemical analysis and toxicity tests of sediments collected in the disposal site and adjacent area. The physicochemical characterization of the sediments involved grain size distribution, concentrations of polycyclic aromatic hydrocarbons (PAHs), chlorinated and aromatic hydrocarbons, polychlorinated bip…
Smith C, Williams J, Nejadhashemi AP, Woznicki S, Leatherman J. 2013. Cropland management versus dredging: An economic analysis of reservoir sediment management. Lake Reserv Manage. 29:151–164. Erosion of agricultural cropland has been identified as a major source of sediment accumulating in water reservoirs. Emphasis is increasingly on finding the most cost-effective ways to control soil er…
The dredged sediments of polluted seaports now raise complex management problems since it is no longer possible to discharge them into the sea. This results in the need to manage them on land, raising other types of technical, economic and environmental problems. Regarding the technical and economic dimensions, traditional waste treatment methods have proved to be poorly adapted, due to very…
