Novel sediment sampling method provides new insights into vertical grain size variability due to marine and aeolian beach processes

In sandy beach systems, the aeolian sediment transport can be governed by the vertical structure of the sediment layers at the bed surface. Here, data collected with a newly developed sand scraper is presented to determine high-resolution vertical grain size variability and how it is affected by marine and aeolian processes. Sediment samples...

Progradation Speed of Tide-Dominated Tidal Flats Decreases Stronger Than LinearlyWith Decreasing Sediment Availability and LinearlyWith Sea Level Rise

We use the results of a one-dimensional morphodynamic model and the basis of the “Lagrangian equilibrium state” (Maan et al., 2015, https://doi.org/10.1002/2014JF003311) to derive a quantitative relationship between the progradation speed of tidal flats and the suspended sediment concentration in their adjacent waters and show that the speed...
