Multi‐annual variability of storm events and morphological response in the SW Iceland: The Valahnúkamöl boulder barrier

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Located on the high‐energy coast of SW Iceland, the boulder barrier of Valahnúkamöl experienced important morphological changes associated with the morphogenetic impact of storm events over annual to pluri‐decadal timescales. Abstract While many studies have highlighted the high mobility of gravel/pebble beaches due to storm waves, further research is ...

Enhancing Road Drainage Systems for Extreme Storms: Integration of a High-Precision Flow Diversion Module into SWMM Code

International Journal of Disaster Risk Science
Urban road networks function as surface passage for floodwater transport during extreme storm events to reduce potential risks in the city. However, precise estimation of these flow rates presents a significant challenge.

The impact of outer‐bar alongshore variability on inner‐bar rip dynamics

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Single, moderate‐scale perturbations in outer‐bar elevation are shown to generate rip channels across an inner bar. The coupling between the inner‐ and outer‐bar channel positions depends on the outer‐bar perturbation depth and transverse slope. The inner‐bar rip may de‐coupled or re‐coupled from the outer bar as channels evolve.

Winter Ice‐Wave Modeling With WAVEWATCH III in Lake Erie

Journal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract Operational wave forecasts for the Great Lakes originate from the NOAA Great Lakes Waves Unstructured version 2 system. The model uses a simple ice blocking (IC0) parameterization for ice‐wave damping, so ice‐covered portions of the lakes are treated as land in the modeling system.

Study on the Influences of Coastline Changes in Hydrodynamic Force and Tidal Prism of Tianjin Offshore Area

MATEC Web of Conferences, 2015
Numerical simulation of Tianjin coastal waters tidal field by using the Mike21 numerical model. The impact of coastline changes in hydrodynamic force and tidal prism of Tianjin offshore area was predicted. Results show that after the change of coastline,

Tsunami propagation and flooding maps: An application for the Island of Lampedusa, Sicily Channel, Italy

Earth Surface Processes and Landforms, Volume 49, Issue 14, Page 4842-4861, November 2024.
The graphical abstract summarizes the tsunami inundation risk assessment for Lampedusa Island. It highlights the study area (Hellenic Arc and Lampedusa), the high tsunamigenic risk of the Hellenic Arc and socio‐economic importance of Lampedusa. The modelling methodology includes the adoption of DELFT‐3D, MIKE 21 FM and HEC‐RAS software.

Large Eddy Simulation of Cross‐Shore Hydrodynamics Under Random Waves in the Inner Surf and Swash Zones

Journal of Geophysical Research: Oceans, Volume 129, Issue 9, September 2024.
Abstract A 3D large eddy simulation coupled with a free surface tracking scheme was used to simulate cross‐shore hydrodynamics as observed in a large wave flume experiment. The primary objective was to enhance the understanding of wave‐backwash interactions and the implications for observed morphodynamics.

Tropical Cyclone Storm Surge‐Based Flood Risk Assessment Under Combined Scenarios of High Tides and Sea‐Level Rise: A Case Study of Hainan Island, China

Earth's Future, Volume 12, Issue 8, August 2024.
Abstract In the context of climate change, coastal flood risk is intensifying globally, particularly in China, where intricate coastlines and frequent tropical cyclones make storm surges a major concern. Despite local government's efforts to initiate coastal monitoring networks and qualitative risk guidelines, there remains a gap in detailed and ...

LiDAR topo‐bathymetry for riverbed elevation assessment: A review of approaches and performance for hydrodynamic modelling of flood plains

Earth Surface Processes and Landforms, Volume 49, Issue 9, Page 2585-2600, July 2024.
When TBL signal reaches riverbed, elevation estimation is accurate. Conditions where depth, bed reflectivity and turbidity cause voids in TBL coverage still need to be understood. Relevance of TBL in critical portions of rivers as required in modelling is still to be demonstrated.

Evaluation and comparison of semi-empirical and numerical methods in predicting wave characteristics in the South Caspian Sea [PDF]

Numerical Methods in Civil Engineering
The prediction of wave parameters based on measured wind parameters plays a crucial role in Coastal and Ocean Engineering. This is particularly important in designing coastal and offshore structures, as there may be limited availability of wave ...
