The Optimization of Four Key Parameters in the XBeach Model by GLUE Method: Taking Chudao South Beach as an Example

Journal of Marine Science and Engineering
When the XBeach model is used to simulate beach profiles, the selection of four sensitive parameters—facua, gammax, eps, and gamma—is crucial. Among these, the two key parameters, facua and gamma, are particularly sensitive.

Numerical modelling of gravel transportation by a tsunami with the extended XBeach-G [PDF]

Applied Ocean Research
Estimating coastal erosion by a tsunami is essential for land use planning, assessing hazards for current structures (e.g., coastal nuclear power plants), and for paleotsunami reconstruction.

Modeling of wave attenuation by vegetation with XBeach

, 2015
Over the past decades the effect of vegetation (e.g. kelp, mangroves, sea grass) on nearshore coastal processes has received more and more attention. In recent years several numerical wave models have been extended to include this effect. In the current study, the numerical storm impact model XBeach was extended with formulations found in literature ...

A Dataset of Two-Dimensional XBeach Model Set-Up Files for Northern California

Data
Here, we describe a dataset of two-dimensional (2D) XBeach model files that were developed for the Coastal Storm Modeling System (CoSMoS) in northern California as an update to an earlier CoSMoS implementation that relied on one-dimensional (1D) modeling

An XBeach derived parametric expression for headland bypassing [PDF]

Coastal Engineering, 2021
Abstract Accurate knowledge of the sediment budget of a coastal cell is necessary for coastal management and predicting long-term coastal change. An important component in the sediment budget of many wave-dominated embayed coastlines is the amount of sediment that bypasses rocky headlands, which present partial barriers to alongshore transport.

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

Bathymetric Data Requirements for Operational Coastal Erosion Forecasting Using XBeach

Journal of Marine Science and Engineering, 2021
There is an increasing interest in the broad-scale implementation of coastal erosion early warning systems (EWS) with the goal of enhancing community preparedness to extreme coastal storm wave events.

Uncertainty in runup predictions on natural beaches using XBeach nonhydrostatic [PDF]

Coastal Engineering, 2021
Abstract The wave time series that forces phase-resolving models is a source of model uncertainty that can propagate into wave runup predictions when the wave phase information is unknown. The effect of beach morphology on the propagation of this intrinsic uncertainty related to wave randomness ( U i ) is largely unexplored.

A Process-Based Model for Arctic Coastal Erosion Driven by Thermodenudation and Thermoabrasion Combined and including Nearshore Morphodynamics

Journal of Marine Science and Engineering, 2022
Various models have recently been developed to describe Arctic coastal erosion. Current process-based models simulate multiple physical processes and combine them interactively to resemble the unique mechanism of Arctic coastal erosion. One limitation of

APPLICATION AND VALIDATION OF XBEACH FOR THREE DIFFERENT FIELD SITES [PDF]

Coastal Engineering Proceedings, 2011
The XBeach model has been applied for different field sites, each having its specific problems. Cases were ranging from typical 1D beach erosion tests during storm conditions (to compare with Durosta results) which were extended to full 2D models to include the effects of curved coasts.
