Numerical Investigation of Wave Overtopping in Impermeable Seawalls Coated with Sand-Based Porous Media [PDF]

Numerical Methods in Civil Engineering
A seawall's structural integrity can be damaged by wave overtopping. To mitigate wave overtopping, this study investigates the effectiveness of incorporating a porous layer into impermeable seawalls.

Reduction of Wave Overtopping and Force Impact at Harbor Quays Due to Very Oblique Waves

Journal of Marine Science and Engineering, 2020
Physical model experiments were conducted in a wave tank at Flanders Hydraulics Research, Antwerp, Belgium, to characterize the wave overtopping and impact force on vertical quay walls and sloping sea dike (1:2.5) under very oblique wave attack (angle ...

Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.

Expected Discharge of Irregular Wave Overtopping

Coastal Engineering 1968, 1968
An experiment was carried out on the overtopping of mechanically generated irregular waves over vertical walls. The experimental discharge was almost in agreement with the expected discharge which had been calculated with the wave height histogram and the data of regular wave overtopping based on the principle of linear summation.

Maturation of River‐Dominated Delta Tops: The Channelized Delta Model

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract We present a novel, laterally averaged model of delta growth, the channelized delta model, in which delta top dynamics are described in terms of channelized (lumped channel) and non‐channelized areas. The maturation level of the lumped channel is defined by a shape factor that dictates flow partitioning between channelized and non‐channelized ...

North Pacific Extreme Storms Reconstructed With a Novel Approach to Estimating Storm Frequency and Uncertainty

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Sedimentary archives of tropical cyclones have been primarily developed in back barrier settings and karst basins at low to mid‐latitude sites in the Atlantic. Here, a unique record of high‐latitude storms is presented from Skan Bay, Unalaska in the Eastern Aleutian Islands. Storm‐induced coarse deposits in a 20.5 m composite sediment core are

Mapping Flood Peak Distributions From Natural Conditions to Post‐Reservoir States and Vice Versa: A Simplified Analytical Framework for Uncontrolled Reservoirs With Spillways Outlet

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The presence of a reservoir along a river modifies downstream flood events by storing and releasing water volumes. By attenuating the peak flows, the structure significantly alters their corresponding probability distributions, particularly in terms of the shape of the distribution.

Numerical Investigation of Storm Surge Effects on Denitrification in Nearshore Aquifers

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Coastal aquifers are highly dynamic environments, sensitive to both regular hydrodynamic forcing and extreme events. Among these, storm surges can significantly alter subsurface flow by expanding the upper saline plume (USP), modifying residence times, and intensifying mixing between fresh groundwater and seawater.

EVALUATION OF MEAN WAVE OVERTOPPING AND MAXIMUM INDIVIDUAL WAVE OVERTOPPING ON ROCK REVETMENT

Jurnal Teknologi (Sciences & Engineering)
An accurate estimation of wave overtopping discharge on rock revetment is important to protect coastal areas from possible hazards. The mean discharge value is often used in the coastal structural design. However, the anticipated impact of the maximum volume of overtopping by individual waves is expected to be significant in wave overtopping ...
