Morphodynamics in a beach with submerged breakwaters [PDF]

open access: yes, 2021
Σήμερα, πάνω από το 40% του παγκόσμιου πληθυσμού κατοικεί σε παράκτιες περιοχές, όπου συγκεντρώνεται και η πλειοψηφία των μεγαλουπόλεων. Η υπερσυγκέντρωση πληθυσμών στις ευαίσθητες αυτές ζώνες συνεπάγεται υπερβολικές πιέσεις τόσο στη στεριά, όσο και στη θάλασσα.

Characteristics of Water Surface Variation around Double-Breaking Type Artificial Reef [PDF]

open access: yes한국해양공학회지, 2019
A submerged breakwater is one of the coastal structures used to reduce wave energy and coastal erosion. However, a submerged breakwater has a negative aspect in that a strong rip current occurring around an open inlet due to a difference in mean water ...

Flume Experiment on the Sediment-Retaining Effect of Submerged Breakwaters under the Combined Action of Waves and Currents

open access: yesJournal of Marine Science and Engineering, 2020
This research was initiated as design guidance for the extension works of a submerged trapezoidal riprap breakwater protecting the channel towards Huanghua Port in China.

A Study on Environmental Submerged Breakwaters

open access: yesPROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 1996
This paper discusses submerged breakwaters with cylindrical fish reefs. Various model tests were carried out to investigate regular and irregular wave transmissions. The tests revealed several fundamental principles about the wave transmission of the reef-type breakwaters. When the reef crest width is large, the wave dissipation can be expected to have

Water waves resonance and its interaction with submerged breakwater

open access: yesResults in Engineering, 2022
Wave resonance phenomena in a basin can cause enormous damage to the environment. Resonance is caused by external forces coming into the basin with a similar period as the natural period of the basin.

Divergent exploratory‐avoidant behavioural strategies may drive niche differentiation in juvenile Antarctic fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

Simulation on the effect of submerged breakwater to the wave transmission and run-up [PDF]

open access: yes, 2013
The construction of submerged breakwater is one of the methods to reduce the effect of wave energy on the beach. Submerged breakwater has many advantages compared to emerge breakwater such lower construction cost, a higher aesthetic values and have a ...

Impact of light pollution on fishes: Mechanisms and ecological consequences

open access: yesJournal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Fertilisation Success in Acanthaster cf. solaris and Acanthaster brevispinus and Reciprocal Hybrid Crosses Across a Range of Sperm Concentrations and Development to the Hybrid Juvenile

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Recent appearance of a mixed species outbreak of coral‐eating crown‐of‐thorns sea stars Acanthaster cf. solaris and the lesser‐known Acanthaster brevispinus in the tropical to subtropical transition zone in eastern Australia have caused management concern due to the potential of hybridisation.
