Careful excavation strategies during the planned Koh Kapik channel dredging will reduce adverse impacts on the riparian mangrove trees. Excavating the outside of the channel bends during low tide and placing removed sediment on the inside of river bends to a minimal height up the mangrove roots will decrease re

Most dredged mud in Shanghai comes from the dredging and dredging works in the Shanghai section of the Yangtze River. The dredged sediment in this area is clean and is a strategic resource that can be effectively utilized [1]. In recent years, Shanghai has vigorously constructed dredging of harbors and channels, and with the continuous promotion of the "National Coastal Harbor Layout Plan

Subsea Mining - Deep Sea Ocean Mining & Seafloor Dredging

Subsea mining, or deep sea mining, is a method of retrieving minerals from the ocean floor. Deepsea mining operations typically occur at depths of 4500 ft. to 12,000 ft. around areas with metallic nodules, as well as areas with high levels of geothermal activity. These geothermal vents have a tendency to create globular deposits of valuable

Brackish Water: Where Fresh Water Rivers Meet A Salt Water Sea

When suspended mud and solids from a river enter the estuary, they encounter the salt front. Unlike fresh water, which rides up and over the saline layer, the sediment falls out of the surface layer into the denser, saltier layer of water moving into the estuary. As it drops, it gets trapped and accumulates on the bottom. Slowly, the estuary grows muddier and muddier, shallower and shallower.

Through the study, it can be found that the main chemical composition of the mud at the bottom of the river and lake is similar to the raw material for the preparation of ceramic grains (Tang et al. 2011; Zhang et al. 2016). Many scholars use river and lake mud to replace non-renewable resources such as clay or shale to prepare ceramic grains and make some research results, the use of river

This report provides the first mud balance for the Trilateral Wadden Sea, making use of a range of data sources such as existing literature, bathymetric charts, sediment distribution maps and measurd deposition rates. We are confident that the report is highly informative and may act as a kind of benchmark study for future work. We wish you pleasant reading! Prof. dr. Piet Hoekstra Hendrikus

Effects of mechanized dredging targeting Chamelea gallina

Mechanized dredging impact on discards was assessed along the northern Alboran Sea (W Mediterranean Sea). Data from 101 dredging operations were analysed for contrasting spatial and seasonal variability of damage, with the use of a three-level damage scale. 4.5% of discarded individuals displayed intermediate damage, whereas 11.3% displayed severe damage.

Computational study of reservoir sand production

An extended form of parametric study was conducted by examining the influence of certain reservoir and well production parameters on the failure and subsequent erosion of the formation material using FEM modelling techniques. The major factors considered include drawdown, wellbore/perforation depth and erosion criterion. In addition, the optimal mud pressure was determined. The adoption of

Production is dependent upon bucket size and the hardness of the material. Breakout forces in excess of 90 t can be exerted by the larger machines, and because of the very high horizontal loads developed by the jigging action the backhoe dredger usually works on spuds. These are heavy pile-like structures which can be dropped into the sea-bed by the dredger. Two spuds are mounted at the

So, unlike in dredging, discharge water goes back where it came from. There will be no ugly plume of mud coming out of the back of the ship.' The system, called 'Seafloor Resource Production System', is actually multiple devices, so three different tools will be used in the production operation itself.
