We predict that portions of the New Jersey continental slope were unstable approximately 0.5 million years ago. This instability was caused by rapid sediment loading during a Pleistocene sea-level lowstand and by flow focusing in underlying, permeable Miocene strata. The simulated instability is consistent with soft-sediment deformation and small slumps in Pleistocene strata of the Hudson Apron...

Abstract Additively manufactured parts are characterized by a peculiar microstructure, originated the distinctive layer-by-layer process. In case of additive technology based on localized melting metallic feedstock, as laser-based powder bed fusion (LPBF), resulting microstructure has hierarchical arrangement, consisting macro- and microscopical features affecting final properties. Commonly, se...

Pre-sedimentation basins are among the most important elements of the conventional water treatment process. In pre-sedimentation basins, due to different velocity gradients, secondary and rotational flows are formed that will create short paths and increase dead and still flow zones as well as changes in the flow mixing. This will prevent laminar flow conditions for sedimentation and will reduc...

During the Deepwater Horizon blowout, thick layers of oiled material were deposited on the deep seafloor. This large scale benthic concentration of oil is suggested to have occurred via the process of Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA). This meta-analysis investigates whether MOSSFA occurred in other large oil spills and identifies the main drivers of oil sedimen...

aluminum base composite materials with variable properties which have been strengthened by alb 2 particles have been widely used. in this study, composites with variable properties of al-5%b and al-2%mg-2%b which are produced through centrifugal casting are investigated as far as their microstructure and hardness are concerned. the microstructure of these composite were studied by using metallo...

Abstract Experimental studies of the effectiveness water distribution methods in a thin-layer sump were carried out on model and semi-industrial installations. When designing sedimentation tanks, it is usually recommended to take η = 0.03-0.07. According our data, when > 0.05, not possible ensure uniform operation all slots (holes), which worsens hydrodynamic conditions settling zone. Experi...

The armored layer is crucial for protecting the riverbed. bed of river a movable material that protects below surface layer. This study aimed to develop formulas estimate thickness mobile armor with noncohesive materials and establish correlation between flow velocity shear stress under conditions erosion sedimentation. research methods included field measurements, laboratory tests, numerical s...
