Wave trapping by porous breakwater near a rigid wall under the influence of ocean current [PDF]

Scientific Reports
The present work investigates the water wave interaction with bottom-standing thick porous trapezoidal-shaped structures and shore-side vertical rigid wall in the presence of uniform ocean currents.

Numerical investigation of steel-casing opening design for penetration through riprap in a macro-tidal estuarine mudflat [PDF]

Scientific Reports
The installation of steel casings in riprap-covered macro-tidal estuarine mudflats is governed by a complex interplay of soil, tidal and pore-water pressures, frequently causing the casing to refuse to penetrate or to deviate from its design alignment ...

Experimental Study on Vertical Bearing and Deformation Characteristics of Qiantang River Ancient Seawall

Buildings, 2023
Situated on the northern bank of the Qiantang River estuary, the ancient seawall serves not only as a national cultural relic but also as an active agent in flood and tide prevention.

SPATIAL DISTRIBUTION OF WAVE-BY-WAVE OVERTOPPING AT VERTICAL SEAWALLS [PDF]

Coastal Engineering Proceedings, 2020
Over the years, many physical and numerical modelling research has been carried out to investigate the wave-structure interactions and the resulting mean overtopping characteristics at sea defences. The most reliable empirical predication formulae for prediction of mean overtopping rates have been reported in the overtopping manual, EurOtop (2018).

Field investigation on the impact of vehicle traffic on the vibration of ancient seawalls in Qiantang River

Frontiers in Marine Science, 2023
To investigate the vibrational impact of vehicular traffic on the ancient Qiantang River seawall, on-site measurements of the seawall’s pulsation and forced vibrations under different vehicle speeds and axle loads were conducted.

Viscous Flow Fields Induced by the Run-Up of Periodic Waves on Vertical and Sloping Seawalls

Journal of Marine Science and Engineering, 2022
Unsteady two-dimensional Reynolds Averaged Navier-Stokes (RANS) equations coupled with the k−ε turbulence model was developed to simulate the viscous flow field near seawalls.

Wave Hydrodynamic Characteristics of Vertical and Sloped Seawalls [PDF]

Bulletin of the Faculty of Engineering. Mansoura University, 2020
The hydrodynamic performance of vertical and sloped plane, rectangular serrated, and triangular serrated seawalls were investigated experimentally in terms of wave reflection coefficient, kr, relative wave run-up, Rup/Hi, and relative wave run-down, Rdown/Hi, using physical model studies.

Eco-Engineering of Seawalls—An Opportunity for Enhanced Climate Resilience From Increased Topographic Complexity

Frontiers in Marine Science, 2021
In the context of “green” approaches to coastal engineering, the term “eco-engineering” has emerged in recent years to describe the incorporation of ecological concepts (including artificially water-filled depressions and surface textured tiles on ...

Experimental Investigation of Wave Propagation and Overtopping over Seawalls on a Reef Flat

Journal of Marine Science and Engineering, 2023
A series of physical model tests were performed to investigate the wave propagation, pressure, and wave overtopping processes for vertical and sloped seawalls on the reef flat.

Breaking Solitary Wave Impact on a Vertical Seawall [PDF]

Water, 2022
Wave interactions with vertical and sloping seawalls are indeed complicated, especially for the impacts due to breaking waves, which are unsteady, turbulent and multi-phase. Available studies successfully measured the impact pressure due to waves acting on seawalls, whereas the associated flow velocity and turbulence characteristic received limited ...
