The behaviour of fines released due to dredging: A literature review
TL;DR: In this article, a DIOC-project was started at Delft University of Technology on the dispersion of fines during sand mining and the behavior and spreading of fines, which are released through the overflow of a dredging ship, is studied.

Alongshore variability of cross‐shore bar behavior on a nontidal beach
Abstract: We report on a 6-year nearshore bathymetric dataset from the Danube Delta (Romanian Black Sea coast) that comprises 16 km of erosive, stable and accumulative low-lying micro-tidal beaches northward of Sf. Gheorghe arm mouth. Two to three two-dimensional longshore sandbars exhibit a net multi-annual cyclic (2.8–5.5 years) offshore migration (20–50 m yr1) in a similar way to other coasts worldwide. Bar morphology and behavior on the sediment-rich accretionary (dissipative) sector differ substantially from that on the erosive (intermediate) sector. Shoreface slope is the most important factor controlling sandbar number and behavior. It determines different wave-breaking patterns in the surf zone, translated into different offshore sediment transport and bar zone widths along the study site. Additionally, sediment availability, as a result of the distance from the arm mouth and of the long-term evolution of the coast, controls the sandbar volume variability. These are all ultimately reflected in the variations of sandbar migration rates and cycle periods. A non-dimensional morpho-sedimentary parameter is finally presented, which expresses the bar system change potential as offshore sediment transport potential across the bar zone.

Residual flow, bedforms and sediment transport in a tidal channel modelled with variable bed roughness
Alan G. Davies,Peter E. Robins +1 more
TL;DR: In this article, the effect of using a spatially/temporally varying ks is assessed with reference to a tidal channel (Menai Strait, N. Wales) in which the variability of the bedforms has been monitored using multi-beam surveying.

Storm-induced hydrodynamic changes and seabed erosion in the littoral area of Yellow River Delta: A model-guided mechanism study
TL;DR: In this paper, a Delft 3D module by observing hydrodynamic and sediment data to simulate the hydrodynamics and seabed erosion during a storm event in the littoral area of YRD is presented.
An estimation of gravel mobility over an alpine river gravel bar (Arc en Maurienne, France) using PIT-tag tracers
TL;DR: In this paper, the authors used passive integrated transducers (PIT) tag method to trace gravel particle movements in mountainous rivers and reported recovery percentages after one flood are often over 80%, demonstrating the effectiveness of this technique for small mountainous rivers.
