Near-bed hydrodynamics and sediment transport in the swash zone
The swash zone, the section of the beach that is alternatingly inundated and exposed as a result of wave runup, is an important part of the nearshore coastal zone because of hydrodynamic and sediment transport processes that affect the morphology and ecology of the broader littoral area. The …

Transport of terrigenous sediment and horseshoe crab eggs in the swash zone of an estuarine foreshore in Delaware Bay, New Jersey, USA
… for egg exhumation and transport in the swash zone is paramount to conservation of species that use the intertidal foreshore. One example where the understanding of these processes is critical to egg exhumation, transport and deposition is in Delaware Bay, USA. Beaches in Delaware Bay …

A laboratory study of the 'shoreline' detected in video imagery
… experiment was undertaken to simulate varying swash zone characteristics and sensor-target geometry found in digital images collected by ARGUS coastal imaging systems. Using a hyperspectral sensor, reflectance data were integrated over the respective red, blue and green wavelengths …

SPH modeling of the vertical flow structure and turbulence in the swash
The vertical structure of swash-zone flows and turbulence, which is critical to sediment transport and flooding due to over-topping of dunes, will be examined using a Smoothed Particle Hydrodynamics model (DualSPHysics) evaluated with field observations obtained near La Jolla, CA in fall 2003. The …

Bed shear stress under wave runup on steep slopes
Extensive measurements of swash hydrodynamics and bed shear stress were obtained for surging, collapsing, plunging and spilling swashes, in both medium and prototype scale fixed-bed laboratory wave flumes with steep slopes (1:3 and 1:6, respectively). The hydrodynamics of swash flows were found to …

Horizontal pressure gradient and bed shear stress under double dam-break driven swash and validation of a Reynolds-Averaged Navier-Stokes equations based model
Swash zone processes drive foreshore morphodynamics through sediment transport gradients. Sediment transport rates are often estimated using bed shear stress as the main hydrodynamic driver. However, the importance of pressure gradients relative to bed shear stress in the swash zone is still poorly …

The morphological, sedimentary and hydraulic properties of two coarse clastic (pebble) beaches along the heritage coast of Glamorgan, Wales
… (C-axis) was the most susceptible parameter to swash/backwash processes, and that tracers possessing relatively larger C-axes travelled relatively further along and down-beach from the injection point. An analysis of the relationship between tracers and the background beach population showed …

Beach development and movement as a function of water waves
… theory and sediment transport in the nearshore zone, with special emphasis on littoral drift. The linear Airy theory for water waves is developed for the computation of longshore current, utilizing certain exact relationships for momentum flux. The near shore beach environment is discussed in …

Physical controls on water flow and solute transport in coastal aquifers
… forcing induces pore water circulations in the swash zone of the near-shore aquifers; wave forcing also modifies the pathways of solute transport in the beach prior to discharge into the ocean, and subsequently impacts plume's residence time, migration speed, discharge location, and discharge …

Experimental And Analytical Investigations Of Solitary Waves On A Beach
… investigations of the flow on a beach, i.e., the swash, due to solitary waves with the objective of understanding the flow processes that govern complex coastal hydrodynamics. The bed shear stress is identified as an important quantity and consequently, a shear plate sensor is developed to make …
