Modelling storm responses on a high-energy coastline with XBeach [PDF]
Modeling Earth Systems and Environment, 2015 The XBeach model has been used to simulate the morphological impacts of storms on sandy and gravel beaches. Taking as a case study Rossbeigh Spit located on the high-energy coast of western Ireland, the study reported here tests the capacity of XBeach to reproduce barrier breaching during a storm in December 2008.

Modelling the morphodynamics of gravel beaches during storms with XBeach-G [PDF]
Coastal Engineering, 2015 AbstractThis paper presents an extension of the XBeach-G numerical model with a sediment transport and morphology module, which includes the effect of groundwater ventilation and flow inertia on sediment transport, to simulate the morphodynamic response of pure gravel beaches and barriers to storms.

Numerical modelling of the 1 July 2022 flooding event, Southwest Huvadhoo Atoll, Maldives: Implications for the future [PDF]
Cambridge Prisms: Coastal FuturesLow-lying atoll islands are among the world’s most vulnerable coastal environments to sea-level rise (SLR). Global application of coastal flooding models suggests that centennial flood events may become annual events by 2050 in tropical regions.

Modeling Impact of Intertidal Foreshore Evolution on Gravel Barrier Erosion and Wave Runup with XBeach-X [PDF]
Journal of Marine Science and Engineering, 2020 This paper provides a sensitivity analysis around how characterizing sandy, intertidal foreshore evolution in XBeach-X impacts on wave runup and morphological change of a vulnerable, composite gravel beach. The study is motivated by a need for confidence

Estimating dune erosion at the regional scale using a meta-model based on neural networks [PDF]
Natural Hazards and Earth System Sciences, 2022 Sandy beaches and dune systems have high recreational and ecological value, and they offer protection against flooding during storms. At the same time, these systems are very vulnerable to storm impacts.

MODELLING INFILTRATION ON GRAVEL BEACHES WITH AN XBEACH VARIANT [PDF]
Coastal Engineering Proceedings, 2011 Coarse-grained beaches are particularly prevalent in the UK, composed of accumulations of either gravel, or mixed sand and gravel sediments. Understanding and predicting their morphological behaviour in response to short-term and long-term forcing has been the subject of recent research. Despite the focus on sandy beaches, it is important to understand

Modelling the Effect of ‘Roller Dynamics’ on Storm Erosion: Sylt, North Sea
Journal of Marine Science and Engineering, 2022 Coastal storm erosion can lead to episodic morphological changes and hinterland flooding that requires sustainable management. An accurate estimation of storm erosion can determine the success of hazard mitigation strategies.

Journal of Marine Science and Engineering, 2021 This paper presents and validates a novel root model which accounts for the effect of belowground biomass on dune erosion volumes in XBeach, based on a small-scale wave flume experiment that was translated to a larger scale.

Modeling Wave Overtopping on a Seawall with XBeach, IH2VOF, and Mase Formulas [PDF]
Water, 2020 The advances in computational fluid dynamics have made numerical modeling a reliable complementary tool to the traditional physical modeling in the study of the wave overtopping phenomenon. This paper addresses overtopping on a seawall by combining the numerical models XBeach (non-hydrostatic and Surfbeat modes) and IH2VOF, and the Mase formulas.
