Rip currents are fast offshore currents generated during the breaking process of waves propagating nearshore, posing a potential life safety threat to coastal bathers. This study utilizes a Boussinesq phase-resolving model to investigate the formation mechanism of rip currents at Dadonghai ...
It is rip-up-clasts mudstone debris and has a short transport distance. Boulder clay and "argillaceous parcel" are argillaceous, dolomitic or sandy lumps in semi-consolidated soft mud at the delta front, which were formed by entrapment of sandstones in the process of sandy debris flow. They ...
(E-F) The Cooperstown outcrop consists of thin, cross-bedded sandstones capped by more massively bedded pebbly sandstone that preserves flaky intraclasts that may represent rip-ups from underlying fluvial strata. (G-H) The Kimberly outcrop consists of a succession of interbedded sandstone and ...
Currents, waves, and tides that occur close to the coast are examples of hydro-oceanographic parameters. Large amounts of marine debris can be carried by waves with great energy [2,39]. High-energy waves arise and have the potential to produce severe storms, especially during the rainy season...
Rip currents are the strong narrow seaward current produced by waves breaking on the coast. Of the many types of rip currents, the present study investigates, experimentally and numerically, the rip current system produced by the wave reflection on a finite-length shore-normal st...
conclusive evidence to suggest that the appearance of cusps and rip currents is due to the presence of standing edge waves during the dry season, the data show that during the period of high energy swell, IG waves exist simultaneously with the cusps as small rhythmic systems of rip currents....
Rip currents accompanied by high concentrations of reflective particles observed at SIO Pier resulted in increases in the MTF. Optically derived particle composition characteristics such as the bulk particle real index of refraction and particle size distribution are shown to be related to the ...
From the period of rapid sea-level fall to the period of rising sea level, the gravity flows may have been increasingly diluted due to sufficient mixing with ambient seawater, resulting in a gradual transformation from sandy debris flows into turbidity currents. In addition, changes in gradient ...
