... for achieving carbon neutrality across scientific and industrial sectors. Effective subsea CO 2 sequestration hinges on macroscopic factors such as salinity, sediment porosity, types of sediments, and additives. Special attention is warranted in exploring CO 2 sequestration in solid gas hydrate form within...

... and the size of the sand. INTRODUCTION Tsunami when approaching the coast carries multiple sediments, stones and debris of different size. These debris often reinforce hazardous impact of tsunami waves on coast and coastal structures, therefore it is very important to know their dynamics. The propagation...

... structures and soft defense measures are attempted. The hard structures, such as groins, offshore breakwaters and seawalls onshore, turn out to cause erosion locally or downstream more or less. Unlike hard structures, beach nourishment, as a soft measure to recharge the eroded coast with sediment from...

... by the reclamation and suspended sediment transport process due to dredging over the intertidal flat, where the tidal current due to local force tide rather than small wave is the dominant dynamic for sediment transport and morphology. A two-dimensional numerical model discretized by a cell-centered finite volume...

... Abstract Annular flume has been widely applied in researches of the laws of sediment motion for its favorable features: it meets the distance requirement of fine sediment settlement without the influence of inflow and outflow; meanwhile, it has such advantages as simple structure and easy...

... Abstract Geotextile mattress with sloping curtain (GMSC), as a flexible structure filled with dredged sediment, may be an advisable alternative countermeasure against erosion since it can make deposited dunes form naturally at upstream and downstream sides of GMSC when installed in erosive...

... ABSTRACT: The runoff and sediment in the Yellow River Delta is significant to the continuous economic development and ecological environment evolution. The analysis of the flow and sediment can provide an important basis for the future control of the River Delta. According to the survey data...

... here in 1996, field observations of meteorology, hydrology, sediment, geology , etc. were emphasized and conducted. A series of of field measurement have been completed since Oct 1996 and abundant data achieved varies from tidal, sea bed morphological to sediment concentration, wave, weather and so...

... ABSTRACT: In JAMSTEC an 11,000-meter class ROV called "ABISMO" (Automatic Bottom Inspection and Sampling Mobile) is being developed. "ABISMO" means an "abyss" in Spanish. The main purpose of ABISMO is the sediment sampling in the deepest sea bottom. The ABISMO started developing in April 2005...

... ABSTRACT: This research presents a comparison data report on surface-water seasonal fluctuation for infiltrating water intake; estimates how bottom ice and bed-material/sediments freezing causes reduction in infiltrative water-intake capacity in frazil ice water. It recommends method...

...) in deep ocean mining system is built by the theory of multi-body system under the respective conditions of flat, slope, trench and obstacle terrain. The mechanical property of seabed sediment in China s mining area is described. The relationship between the shear stress and sediment depth, and the maximum...

.... INTRODUCTION The low axial capacities of driven piles in calcareous sediments have provided major problems for the designers of offshore structures founded on these soils. These sediments are widely distributed on the continental shelves in tropical and temperate regions of the world, and are found m many...
