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

Journal of Geophysical Research: Earth Surface, 2022
Estuaries 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.

The aeration and dredging stimulate the reduction of pollution and carbon emissions in a sediment microcosm study [PDF]

Scientific Reports
Sediment dredging and aeration are used as important technical measures to remediate internal loading of sediment in polluted rivers. However, previous studies have overlooked the impact of dredging and aeration on Greenhouse gases (GHGs) emission.

Effects of Sediment Dredging on Nutrient Release and Eutrophication in the Gate-Controlled Estuary of Northern Taihu Lake

Journal of chemistry, 2021
Estuarine zones are regarded as the ecotones connecting the rivers and lakes. Sediment dredging is a conventional treatment technology that is widely used to remove the internal loading in estuarine zones worldwide. However, what is the characteristic of

Two-phase modelling for sediment water mixtures above the limit deposit velocity in horizontal pipelines

Journal of Hydrology and Hydromechanics, 2021
In dredging applications, deep sea mining and land reclamation projects typically large amounts of sediments are transported through pipes in the form of hyper concentrated (40% sediment or more) sediment-water mixtures or slurries.
