Storm-driven erosion and inundation of barrier islands from dune-to region-scales

open access: yesCoastal Engineering, 2020
Barrier islands are susceptible to erosion, overwash, and breaching during intense storms. However, these processes are not represented typically in large-domain models for storm surge and coastal inundation.

The relative influence of dune aspect ratio and beach width on dune erosion as a function of storm duration and surge level

open access: yesEarth Surface Dynamics, 2021
. Dune height is an important predictor of impact during a storm event given that taller dunes have a lower likelihood of being overtopped than shorter dunes.

Ensemble technique application to an XBeach-based coastal Early Warning System for the Northwest Adriatic Sea (Emilia-Romagna region, Italy) [PDF]

open access: yes, 2022
During the last three decades, ensemble modelling has switched the focus from deterministic to probabilistic outcomes after its successful application in meteorological forecasting.

Numerical modelling of intra-wave sediment transport on sandy beaches using a non-hydrostatic, wave-resolving model

open access: yesDeutsche Hydrographische Zeitschrift, 2020
The mutual feedback between the swash zone and the surf zone is known to affect large-scale morphodynamic processes such as breaker bar migration on sandy beaches.

Numerical Simulation of the Locality of Erosional Damages by Storm Waves in Searching for Measures to Conserve Bonggil Beach, Korea

open access: yesFrontiers in Marine Science, 2022
Coastal erosion caused by extreme storms can reduce the value of beaches. Under the scenario of climate change, the storm intensity may increase and the resulting severe erosion can lead to disastrous damages on the beaches.

XBeach Process-Based Modelling of Coastal Morphological Features Near Breakwater

open access: yes, 2018
An effective role of a detached breakwater as a coastal protection structure leads to morphological evolutions of tombolo. This paper presents the application of process based model of XBeach to investigate the morphological tombolo evolution using the ...

Estimates of Extreme and Low Frequency Reef‐Flat Water Levels at Ipan, Guam From Offshore Waves

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Wave and water level observations collected at a shore‐attached fringing reef at Ipan, Guam are used to relate offshore wave conditions and reef water levels to extreme water levels near the shoreline (2% $\%$ exceedance, η2 ${\eta }_{2}$). The observations capture conditions during three extreme storm events, including Typhoon Dolphin that ...

Role of the forcing sources in morphodynamic modelling of an embayed beach

open access: yesEarth Surface Dynamics
. The sensitivity of a 2DH coastal area (XBeach) and a reduced-complexity (Q2Dmorfo) morphodynamic model to using different forcing sources is studied.

Assessing Drivers of Alongshore Variation in Historical Coastal Dune Evolution: A Field and Model‐Based Approach

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract The protective services provided by coastal foredunes vary spatially due to alongshore differences in dune morphology and hydrodynamic forcing. This study aims to quantify the drivers of alongshore variability of dune evolution across spatial (40‐km) and temporal (multi‐decadal) scales. The alongshore variability in dune evolution is extracted

Generation and Dissipation of Infragravity Waves Over Natural and Engineered Chenier Plain During Hurricane Laura

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Infragravity (IG) waves play a crucial role in nearshore hydrodynamics and sediment transport; however, their generation and dissipation mechanisms during extreme storms remain challenging to assess due to limited data availability, site‐specific characteristics of natural landscapes, and anthropogenic effects.
