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 ...

Sea-level change and the supralittoral environment: Potential impact on a splashpool habitat on the Ligurian coast (NW Mediterranean)

Journal of Biological Research, 2022
Climate change represents one of the major drivers of habitat modification that is affecting a wide variety of environments. In coastal environments, great effort is being put in trying to understand and forecast the possible effects of such processes ...

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

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 ...

Stormtools Design Elevation (SDE) Maps: Including Impact of Sea Level Rise

Journal of Marine Science and Engineering, 2020
Many coastal communities in the US use base flood elevation (BFE) maps for the 100-year return period, specified on Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs), to design structures and infrastructure.

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

SnapWave: fast, implicit wave transformation from offshore to nearshore [PDF]

Geoscientific Model Development
This paper presents an efficient, implicit, unstructured-grid wave propagation model, SnapWave (Roelvink, 2025), which provides a simple and fast way to predict nearshore wave conditions at specified locations, for coastline models such as ShorelineS ...

Present and future flooding and erosion along the NW Spanish Mediterranean Coast

Frontiers in Marine Science, 2023
Coastal flooding and eros-ion caused by extreme events are the main factors responsible for beach hazards. This effect will be exacerbated by the sea level rise induced by climate change.

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.

Improving predictions of swash dynamics in XBeach: The role of groupiness and incident-band runup

, 2018
In predicting storm impacts on sandy coasts, possibly with structures, accurate runup and overtopping simulation is an important aspect. Recent investigations (Stockdon et al., 2014; Palmsten and Splinter, 2016) show that despite accurate predictions of ...
