Hydrodynamics and Sediment Transport Under Solitary Waves in the Swash Zone

Journal of Marine Science and Engineering
Swash–swash interaction is a common natural phenomenon in the nearshore region, characterized by complex fluid motion. The characteristics of swash–swash interaction are crucial to sediment transport, subsequently affecting the beach morphology.

Bottom changes in coastal areas with complex shorelines

Engineering Applications of Computational Fluid Mechanics, 2017
A model for the sea-bottom change simulations in coastal areas with complex shorelines is proposed. In deep and intermediate water depths, the hydrodynamic quantities are calculated by numerically integrating the contravariant Boussinesq equations ...

Trophodynamic variations on microtidal North Mediterranean sandy beaches

Oceanologia, 2005
Trophic models of the micro and meiobenthic community of six sandy beaches on the Ligurian coast (north-western Mediterranean Sea) have been performed to assess variations in structure and function of the ecosystem.

Apresentação de recente metodologia útil para a gestão do risco no litoral

Territorium: Revista Portuguesa de riscos, prevenção e segurança
Os métodos tradicionais de estudo hidrodinâmico das ondas e de batimetria, no domínio litoral de menor profundidade, desde a zona de rebentação (breaker zone) à zona de espraio (swash zone) são difíceis de serem efectuados.

Beach Profile Evolution towards Equilibrium from Varying Initial Morphologies

Journal of Marine Science and Engineering, 2019
The evolution of different initial beach profiles towards the same final beach configuration is investigated based on large-scale experimental data. The same wave condition was performed three times, each time starting from a different initial profile ...

Surf and swash zone hydrodynamics forced by oblique, monochromatic waves in a wave basin with a smooth, impermeable beach

Applied Ocean Research
Beaches are coastal features that offer economic benefits, ecosystem services, and natural barriers against flooding. Sustainable management of beaches requires a firm understanding of hydrodynamics and sediment transport processes.

Relationship between high-frequency sediment-level oscillations in the swash zone and inner surf zone wave characteristics under calm wave conditions

Open Geosciences, 2016
Swash zone topography rapidly responds to the surf zone waves. Understanding how sandy beaches respond to wave action is critical for beach erosion research, and plays a critical role in the design and maintenance of shore protection structures. The main

Microfungal diversity in the swash zone interstitial water (SZIW) of three Ligurian urban beaches (NW, Italy)

Italian Journal of Mycology, 2017
Microfungal species abundance and specific composition of three urban beaches near Genoa (Liguria, NW Italy) in the swash zone interstitial water (SZIW) were evaluated. These beaches are characterized by a high presence of tourists. The investigation was

Motion of water and sediment due to non-breaking waves in the swash zone

Oceanologia, 2012
A long wave run-up theory is applied to the modelling of wave-induced flow velocities, sediment transport rates and bottom changes in a swash zone. First, the properties of the water tongue motion and the resulting lithodynamic response are analysed ...

Swash zone morphodynamics

, 2003
The morphodynamical evolution of four beaches in Europe have been monitored during swash processes, together with the fluctuations of the water table and the recording of the hydrodynamical conditions.
