Fine Sediment Dispersion in the Addu-City Dredging and Reclamation Project

Journal of Marine Science and Engineering
The matter of the quantification of the fraction of the dredged sediment that is released by a trailing suction hopper dredger into the surrounding waters, also known as the passive phase of the plume during dredging operations through the overflow, is a

Dredging Operations and Environmental Research Program: Building Tools for Objective Determination of Environmental Windows

, 2003
Environmental windows have become a prevalent dredging project management practice. Frequently decisions regarding windows are made in the absence of conclusive evidence that dredging does or does not pose a significant threat to specific resources ...

Experimental investigation of cohesive soil erosion caused by translating submerged inclined water jets

Applied Ocean Research
Very limited research has been carried out to investigate sediment erosion caused by subaqueous inclined water jets, despite the fact that such water jets are used in subsea engineering (e.g., dredging, trenching, and deep sea mining).

Effects of Sea‐Level Rise on Dredging and Dredged Estuary Morphology

Journal of Geophysical Research: Earth Surface, 2022
AbstractEstuaries and deltas worldwide are facing land loss and drowning due to sea‐level rise (SLR). Commonly home to ports, their channels are dredged and deepened for navigation. However, little is known about how such sediment management will interact with changing sediment transport patterns due to SLR. Using scale experiments, empirical relations
