MONITORING AND MODELING COASTAL MORPHOLOGICAL CHANGES USING VIDEO DATA AND XBEACH MODEL

Coastal Engineering Proceedings
Coastal areas are highly dynamic environments, subject to morphological changes due to the action of waves, tides, and winds. Monitoring these changes is crucial for understanding coastal evolution and planning sustainable management strategies. This study aims to analyze shoreline changes, sediment accumulation patterns, and crucial beach parameters ...

Observations of Sea‐Swell Wave Reflection From a Steep, Nearshore Bar

Earth and Space Science, Volume 12, Issue 4, April 2025.
Abstract Wave reflection near the beach affects the energy reaching the shore, surfzone wave conditions, and sediment transport. Many prior studies have shown strong reflection of infragravity (0.01 < frequency < 0.05 Hz) wave energy from steep foreshore slopes.

Climate Adaptation for a Natural Atoll Island in the Maldives ‐ Predicting the Long‐Term Morphological Response of Coral Islands to Sea Level Rise and the Effect of Hazard Mitigation Strategies

Earth's Future, Volume 13, Issue 4, April 2025.
Abstract Coral atoll islands, common in (sub)tropical oceans, consist of low‐lying accumulations of carbonate sediment produced by fringing coral reef systems and are of great socio‐economic and ecological importance. Previous studies have predicted that many atoll islands will become uninhabitable before the end of this century due to sea level rise ...

Wave Hydrodynamics in Ports: Numerical model assessment of XBeach

, 2016
Wave climate in harbours determines for a significant part the efficiency of harbour operations. A good prediction of the hydrodynamics is therefore regarded as indispensable, which is often done by means of advanced numerical modelling.

Future Coastal Tundra Loss Due To Compounding Environmental Changes in Alaska

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 4, April 2025.
Abstract Anthropogenic climate change is amplified in the Arctic, where less sea ice enables more energetic wave climates while higher air and soil temperatures increase tundra erodibility. These compounding environmental changes are likely to exacerbate retreat of coastal tundra yet remain poorly constrained on timescales relevant to storm wave ...

Predicting Morphological Changes Along a Macrotidal Coastline Using a Two‐Stage Machine Learning Model

Water Resources Research, Volume 61, Issue 4, April 2025.
Abstract Understanding and predicting coastal change is of the foremost importance to protect coastal communities and coastal assets. This study analyzes field data from 125 locations along the Morecambe coastline, consisting of beach transects collected twice a year for more than a decade (2007–2022).

Stability of Beach Nourishment Under Extreme Wave Conditions: Insights from Physical-Model Experiments and XBeach Simulations

Journal of Marine Science and Engineering
Beach nourishment is a widely adopted nature-based solution for coastal erosion; however, its design efficacy and morphodynamic resilience under extreme wave conditions remain inadequately quantified, posing challenges for coastal hazard assessment. This

Determining the Relative Contributions of Runoff, Coastal, and Compound Processes to Flood Exposure Across the Carolinas During Hurricane Florence

Water Resources Research, Volume 61, Issue 3, March 2025.
Abstract Estimates of flood inundation generated by runoff and coastal flood processes during tropical cyclones (TCs) are needed to better understand how exposure varies inland and at the coast. While reduced‐complexity flood models have been previously shown to efficiently simulate TC flood processes across large regions, a lack of detailed validation

XBEACH MODELLING OF A MIXED SAND AND GRAVEL SHORELINE: EAST VANCOUVER ISLAND

Coastal Engineering Proceedings
The study site is a coastal spit located in the Englishman River estuary, located at Parksville, British Columbia approximately 80 km west of Vancouver as shown in Figure 1. In this paper, we present a holistic approach to evaluating nature-based solutions and assessing coastal processes of a mixed sediment shoreline by integrating coastal process ...
