Sediment Transport From Beach Around Coastal Structures To Submarine Canyon

Earthquakes drive large-scale submarine canyon development and sediment supply to deep-ocean basins

Although the global flux of sediment and carbon from land to the coastal ocean is well known, the volume of material that reaches the deep ocean-the ultimate sink-and the mechanisms by which it is transferred are poorly documented. Using a globally unique data set of repeat seafloor measurements and samples, we show that the moment magnitude (Mw) 7.8 November 2016 Kaikōura earthquake (New Zeala...

Sediment Transport Modelling for Coastal Morphodynamics

The accurate prediction of sand transport rates in the coastal zone depends not only upon the choice of sediment transport model but also, rather critically, upon the formulation used to predict the bed roughness (ks). Sand transport rates are modelled here using both a One-equation, turbulence-closure, TKE-model and also Bijker’s sand transport model. Following some remarks about the nature an...

Impact of Bottom Trawling on Deep-Sea Sediment Properties along the Flanks of a Submarine Canyon

The offshore displacement of commercial bottom trawling has raised concerns about the impact of this destructive fishing practice on the deep seafloor, which is in general characterized by lower resilience than shallow water regions. This study focuses on the flanks of La Fonera (or Palamós) submarine canyon in the Northwestern Mediterranean, where an intensive bottom trawl fishery has been act...

Wave Induced Mine Burial and Sediment Transport in Coastal Environment: Wave and Sediment Transport Modeling Studies

The long-term goal of this work is to develop numerical simulation techniques for predicting waveinduced sediment transport and bed evolution in the coastal zone (order 10 meter depth outside the surf zone), at horizontal scales of tens of meters or less, and the scouring/burial around objects/obstacles (mine-like), partially buried in the bottom. This research was initially motivated by the Na...
