TLDR
In this article, the authors investigated the role of capillarity effects as the primary mechanism driving rapid and relatively large magnitude water table fluctuations within the swash zone and concluded that the rapid rise and fall of the water table under the sand zone do not equate to regions of the beach face alternating between states that favor sediment deposition (unsaturated) and erosion (saturated).About:

Journal ArticleDOI
Hydrodynamics and sediment transport in the swash zone: a review and perspectives
Berry Elfrink,Tom E. Baldock +1 more
TL;DR: In this paper, the dominant hydrodynamic forcing and resulting sediment transport mechanisms in the swash zone are reviewed, combined with a discussion of future measurement and modelling requirements, and the strengths and weaknesses of different approaches identified.
Journal ArticleDOI
Swash infiltration-exfiltration and sediment transport
Ian L. Turner,Gerhard Masselink +1 more
TL;DR: In this article, the authors used field measurements of vertical pore-pressure gradients within the bed to quantify instantaneous (8 Hz) rates of swash infiltration-exfiltration across the beach face.
Journal ArticleDOI
Groundwater dynamics in subterranean estuaries of coastal unconfined aquifers: Controls on submarine groundwater discharge and chemical inputs to the ocean
TL;DR: A review of the effect of factors that influence flow and salt transport in STEs, evaluates current understanding on the interactions between these influences, and synthesizes understanding of drivers of nutrient, carbon, greenhouse gas, metal and organic contaminant fluxes to the ocean.
Journal ArticleDOI
The influence of swash infiltration–exfiltration on beach face sediment transport: onshore or offshore?
TL;DR: In this article, an apparent conflict exists in the literature regarding the net effect of infiltration-exfiltration on the sediment transport, through the combined effects of stabilisation-destabilisation and boundary layer modification.

TL;DR: In this paper, the authors focus on the most common type of IG waves, those induced by the presence of groups in incident short waves, and three related mechanisms explain their generation: (1) the development, shoaling and release of waves bound to the short-wave group envelopes (2) the modulation by these envelopes of the location where short waves break, and (3) the merging of bores (breaking wave front, resembling to a hydraulic jump) inside the surfzone.

Hydraulics of Groundwater
TL;DR: The reference record was created on 2004-09-07, modified on 2016-08-08 as discussed by the authors, using the reference record of the Ecoulement souterrain reference record.
Book
Coastal Bottom Boundary Layers and Sediment Transport
TL;DR: In this article, a review of bottom boundary layer flows including the boundary layer interaction between waves and steady currents is presented, and the concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment diffusivity.
Journal ArticleDOI
Tidal dynamics of the water table in beaches
TL;DR: In this article, the authors investigated the water table height inside a sloping beach via field measurements and theoretical considerations, and found that even in the absence of precipitation, the time averaged inland water table stands considerably above the mean sea level.
Journal ArticleDOI
The capillary fringe and its effect on water-table response
TL;DR: In this article, the authors show that if the zone of tension saturation extends to ground surface, then the addition of a very small amount of water can result in an immediate and large rise in the water table.
