Composition, structure and zonation of intertidal macrofauna in relation to physical factors in microtidal sandy beaches at Río de Janeiro State, Brazil

Scientia Marina, 2003
The intertidal macroinfauna of fiftheen exposed sandy beaches located in Rio de Janeiro State was studied to determine species richness, density, biomass and zonation. Morphodynamic influence on biological parameters is also evaluated in this paper. Dean´

Study on the sediment initiation considering the seepage in the swash zone

Shui kexue jinzhan, 2019
In order to reveal the effects of seepage on the sediment initiation in swash zone,the experimental and numerical studies were performed in this paper. Firstly,the experiments of solitary wave run-up over permeable and impermeable slope was carried out ...

Lidar Observations of the Swash Zone of a Low-Tide Terraced Tropical Beach under Variable Wave Conditions: The Nha Trang (Vietnam) COASTVAR Experiment

Journal of Marine Science and Engineering, 2020
A field experiment was conducted at a tropical microtidal intermediate sandy beach with a low tide terrace (Nha Trang, Vietnam) to investigate the short-term swash-zone hydrodynamics and morphodynamics under variable wave conditions.

Resonances in an Evolving Hole in the Swash Zone [PDF]

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2012
Water oscillations observed in a 10-m-diameter, 2-m-deep hole excavated on the foreshore just above the low-tide line on an ocean beach were consistent with theory. When swashes first filled the initially circular hole on the rising tide, the dominant mode observed in the cross-shore velocity was consistent with a zero-order Bessel function solution ...

Changes in beach shoreline due to sea level rise and waves under climate change scenarios: application to the Balearic Islands (western Mediterranean) [PDF]

Natural Hazards and Earth System Sciences, 2017
This work assesses the impacts in reshaping coastlines as a result of sea level rise and changes in wave climate. The methodology proposed combines the SWAN and SWASH wave models to resolve the wave processes from deep waters up to the swash zone in ...

The Tricky Task of Fisher-Gardener Research in Conservation Paleobiology

Frontiers in Ecology and Evolution, 2022
The study of sambaquis (ancient shell mounds) in conservation paleobiology is a complicated subject, especially when comparing body sizes of current and past mollusk valves to observe possible changes. There is a lack of information regarding how ancient
