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

Journal 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 ...

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

Journal 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

Journal 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.

CALIBRATION OF THE XBEACH-GRAVEL MODEL [PDF]

Symposium proceedings of 18th International Symposium Water Management & Hydraulic Engineering (WMHE 2024)
Despite the natural and economic importance of maintaining gravel beaches in Croatia, there is a lack of knowledge about the resilience of the beach to various wave impacts and the frequency of storm events, as well as specific numerical models for predicting the morphological response of the gravel beach to storm events.

Foredunes in Front of Secondary Dunes Exhibiting Strong Reduction Potential in Storm Wave Settings: A 2D Experimental and Numerical Study

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Coastal zones need further investigations of beach dune erosion to improve storm‐surge protection measures in light of climate change. This study presents a hybrid approach investigating the influence of coastal foredunes on storm‐induced secondary dune erosion.

Field Observations and Geotechnical Modeling of Dune Face Erosion During a Storm (Narrabeen Beach, Australia)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Quantifying dune face failure during storm wave conditions is critical for improving the predictive capability of coastal erosion models. However, most high‐resolution dune erosion observations used to validate these models were obtained from reduced‐scale laboratory experiments, raising questions about their applicability to field‐scale dunes.

Simulating Destructive and Constructive Morphodynamic Processes in Steep Beaches

Journal of Marine Science and Engineering, 2021
Short-term beach morphodynamics are typically modelled solely through storm-induced erosion, disregarding post-storm recovery. Yet, the full cycle of beach profile response is critical to simulating and understanding morphodynamics over longer temporal ...

APPLYING XBEACH ON 7,300 KM COAST: COASTAL CLIFF RETREAT DURING A STORM

Coastal Engineering Proceedings, 2020
Denmark is surrounded by more than 7,300 km soft coastline considered at high risk of storm erosion. The presence of more than 13,000 groins, shore parallel breakwaters and revetments clarify the need of protecting infrastructure and property against coastal erosion in a changing climate.

Role of the Initial Topobathymetry in Washover Deposit Formation During Extreme Events

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Low‐lying beaches, important ecological and socio‐economic assets, are vulnerable to storm erosion and flooding impacts, which are expected to increase due to climate change. This conceptual study uses the 2DH XBeach model to simulate the influence of the initial topobathymetric shape on the washover deposit formation during a beach overwash ...
