Water waves overtopping over barriers [PDF]

, 2019
A numerical and experimental analysis of the wave overtopping over emerged and submerged structures, is presented. An original model is used in order to simulate three-dimensional free surface flows. The model is based on the numerical solution of the motion equations expressed in an integral form in time-dependent curvilinear coordinates.

Experimental investigation of a novel adjustable-slope onshore overtopping wave energy converter for coastal protection and energy generation

Energy Conversion and Management: X
Wave Energy Converters (WECs) are increasingly being proposed for hybrid coastal infrastructure, offering both renewable energy generation and coastal protection to reduce the high Levelized Cost of Electricity (LCoE) associated with wave energy. Onshore

Overtopping Wave Detection based on Wave Contour Measurement

IEEJ Transactions on Electronics, Information and Systems, 2007
The overtopping wave which is high wave exceeding breakwaters causes damage to a coast area. In this paper, we describe a novel detection method of the overtopping wave and other high wave from a video sequence of a coastal camera. This detection is performed directly by measuring wave contour in each image using Active Contour Models and by tracking ...

Reducing Wave Overtopping on Rubble Mound Breakwaters Using Floating Kelp Farms

Journal of Marine Science and Engineering
Near-surface floating kelp farms constitute a Nature-Based Solution (NBS) capable of damping incident wind-generated waves, which might be beneficial to reduce wave overtopping on maritime structures.

Multiscale Numerical Modeling of Wave Overtopping for Pedestrian Hazard Classification and Risk Assessment

Journal of Marine Science and Engineering
The risk of wave overtopping is amplifying under sea-level rise and increased frequency of extreme coastal events. Conventional empirical and physical methods for estimating overtopping characteristics are limited by site-specific assumptions, which ...

Comparative study on wave overtopping reduction performance on a novel dike-front wave dissipation basin and other engineering measures

Applied Ocean Research
A dike-front Wave Dissipation Basin (WDB) is proposed as an engineering measure to reduce wave overtopping discharge over sea dikes. Flume tests are conducted to quantify the overtopping reduction effectiveness of the WDB and to compare it with other ...

Numerical Simulation of Wave Overtopping From Armour Breakwater by Considering Porous Effect

نشریه مهندسی دریا, 2016
Wave overtopping on the breakwaters is an important issue in breakwaters’ design. Most of the previous studies focused on experimental researches and numerical modeling of irregular wave overtopping particularly on porous breakwaters has not been studied.

PRESSURE UPON VERTICAL WALLS FROM OVERTOPPING WAVES

Coastal Engineering Proceedings, 1972
This paper is concerned with the study of wave pressures exerted upon breakwaters of the vertical type from overtopping waves- The formulae for maximum wave pressure upon vertical walls and the wave crest elevation for overtopping waves are suggested by the author. The phase interval method for the maximum wave pressure is also given.
