Direct Policy Search for a Risk‐Based Levee Design Framework With Scenario Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Risk‐based management of coastal flood risk using realistic, process‐based models poses computational challenges, particularly when addressing uncertainties like sea‐level rise. This study explores the use of direct policy search (DPS) as a state‐dependent, adaptive decision‐making approach for upgrading levee systems.

Impact of an extreme storm event on a multiple intertidal barred coastal system

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Extreme storms do not necessarily cause extreme coastal erosion. Integrated DGPS surveys and SWAN nearshore wave modelling reveal that Storm Barra's peak coincided with a low‐tide stage, allowing multiple intertidal bars (MITBs) to dissipate incoming wave energy before it reached Dundrum Bay's shoreline, highlighting the combined role of tidal stage ...

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.

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.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

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.

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 ...

Wave Energy Transfer in Shallow Water: Numerical Investigation of Slope and Offshore Wave Condition Effects

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract This study advances the understanding of nonlinear wave interactions in shallow water by numerically quantifying how foreshore slope and offshore conditions influence energy transfer and wave evolution over a broad range of conditions. Two non‐hydrostatic models, SWASH and XBeach, are validated against physical experiments and applied across a

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 ...
