Dredging, as a topic, encompasses the suite of engineering and environmental practices involved in the excavation, removal, and relocation of sediments or unconsolidated materials from the beds of rivers, lakes, estuaries, and coastal or offshore zones. Research on dredging addresses hydrodynamic and sediment-transport processes, geotechnical characterization of deposits, contaminant mobilization and fate, and impacts on benthic habitats and water quality. It also covers technical aspects of dredging equipment and methodologies, optimization of dredge routing and efficiency, beneficial reuse of dredged material, regulatory frameworks, and monitoring and mitigation strategies to minimize ecological disturbance and geomorphological alteration.
Namibia has granted environmental clearance for an offshore phosphate mining project that paves the way for the world's first commercial seabed-dredging operation for the mineral, despite opposition from green groups and ...
