Modeling Multi-Fraction Coastal Aeolian Sediment Transport With Horizontal and Vertical Grain-Size Variability

Grain size affects the rates of aeolian sediment transport on beaches. Sediment in coastal environments typically consists of multiple grain-size fractions and exhibits spatiotemporal variations. Still, conceptual and numerical aeolian transport models are simplified and often only include a single fraction that is constant over the model...

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...

Impact of sand nourishments on hydrodynamics and swimmer safety

Artificial sand nourishments are a common measure to mitigate coastal erosion problems. Such nourishments can have an impact on currents and waves near the beach, especially when the nourishment has a large size. As nourished beaches often have a recreational function, these altered wave and current patterns may pose a threat to swimmers. This...

Coastal Erosion and Solutions: A primer

This primer describes some of the causes of coastal erosion and tries to put into perspective their scale and consequences. There are no uniform causes, just as there are no uniform solutions. Erosion tends to be site-specific. Yet, with careful observation and measurement, a particular problem can be placed in context and draw from the...

Coastal Dynamics

This book deals on "Coastal Dynamics", which will be defined in a narrow sense as a mathematical theory, which starts from given equations of motion for the sediment, which leads with the continuity equation and given boundary conditions to a calculated (eventually schematized) coastal topography, which is generally a function of time. This is...
