Experimental Study on the Influence of Berms and Roughness on Wave Overtopping at Rock-Armoured Dikes

open access: yesJournal of Marine Science and Engineering, 2020
The average overtopping discharge is an important parameter for the design and reinforcement of dikes. Rock armour on the waterside slopes and berms of dikes is widely used to reduce the wave overtopping discharge by introducing slope roughness and ...

Research on the Dynamic Performance of a Novel Floating Offshore Wind Turbine Considering the Fully-Coupled-Effect of the System

open access: yesJournal of Marine Science and Engineering, 2022
Floating offshore wind turbines (FOWTs) still face many challenges in improving platform stability. A fully submersible FOWT platform with inclined side columns is designed to tackle the current technical bottleneck of the FOWT platform, combining the ...

Statistical Analysis of the Stability of Rock Slopes

open access: yesJournal of Marine Science and Engineering, 2019
Physical model tests were performed in a wave flume at Deltares with rock armoured slopes. A shallow foreshore was present. At deep water, the same wave conditions were used, but by applying different water levels, the wave loading on the rock armoured ...

Crown Wall Modifications as Response to Wave Overtopping under a Future Sea Level Scenario: An Experimental Parametric Study for an Innovative Composite Seawall

open access: yesApplied Sciences, 2020
The overtopping phenomenon at the rear side of breakwaters has particular importance in harbor protection. Undoubtedly, this topic needs to be taken even more seriously, considering the sea level rise.

Damages to Coastal Structures

open access: yesCoastal Engineering 1974, 1974
Coastal Engineering literature contains many references to coastal structures in the design or construction stage but few references to these same structures concerning their maintenance effectiveness subsequent to completion. This paper describes a successful long-term maintenance history of major coastal public structures in the State of California ...

Validation and Comparisons of Methodologies Implemented in a RANS-VoF Numerical Model for Applications to Coastal Structures

open access: yesJournal of Marine Science and Engineering, 2022
Methodologies to be used in numerical models based on Reynolds-averaged Navier–Stokes (RANS) equations and the volume of fluid (VoF) to deal with waves over coastal structures, which involve wave breaking and overtopping and porous structures, are shown ...

Effect of Variations in Water Level and Wave Steepness on the Robustness of Wave Overtopping Estimation

open access: yesJournal of Marine Science and Engineering, 2020
The wave overtopping discharge at coastal defense structures is directly linked to the freeboard height. By means of physical modelling, experiments on wave overtopping volumes at sloped coastal structures are customarily determined for constant water ...

Seasonal changes in beach resilience along an urbanized barrier island

open access: yesFrontiers in Marine Science, 2022
Beach width, dune height, and vegetation coverage are key parameters to assess beach resistance and resilience to storms. However, coastal development often causes beach ecosystem degradation due to poor coastal management.

Lithodynamic Processes along the Seashore in the Area of Planned Nuclear Power Plant Construction: A Case Study on Lubiatowo at Poland

open access: yesEnergies, 2021
The Polish government has made a decision to build a nuclear power plant (NPP) in the South Baltic coastal zone. This means that three major types of structures will be located in the nearshore: (1) breakwaters and a wharf where ships may dock to load ...

Numerical study of spudcon penetration on two-layered soil with Lagrangian-Eulerian couple [PDF]

open access: yesفناوری‌های پیشرفته در بهره‌وری آب, 2023
IntroductionJackup rigs are one of the most widely used and popular offshore structures in semi-deep waters due to their mobility. The new jackups usually consist of a floating triangular body supported by three independent vertical truss legs that can ...
