TL;DR: In this paper, the authors present a fully comprehensive implementation of wave generation and active wave absorption for second-order longcrested monochromatic and random waves in a WCSPH-based (Weakly Compressible Smoothed Particle Hydrodynamics) model.

TL;DR: In this paper, an improved numerical scheme and a different way of simulating the propagation of directionally-spread short wave groups in XBeach was proposed to better predict the groupiness of the short waves and the resulting infragravity waves.

TL;DR: The GOW2 database as discussed by the authors is a long-term wave hindcast covering the world coastline with improved resolution in coastal areas and along ocean islands, which can be used both directly or as boundary conditions for regional and local downscalings.

TL;DR: In this paper, a detailed numerical modelling study was conducted to examine the model skill and the processes governing the initial morphological response of the Sand Engine and the adjacent coastline. But neither the skill of current state-of-the-art models for such predictions nor the primary drivers that control the evolution are known.

TL;DR: In this article, a multi-dimensional Eulerian two-phase model for sediment transport, called SedFoam, is presented, which is able to resolve processes in the concentrated region of sediment transport.

TL;DR: In this paper, the mesh-free code DualSPHysics is applied to simulate the interaction between sea waves and an Oscillating Water Column device (OWC) and the model was first validated with one laboratory test that consists of a fixed OWC with an open chamber.

TL;DR: In this article, a buoyancy-modified k-ω SST turbulence model was proposed to suppress the turbulence level at the interface between water and air in a numerical wave flume.

TL;DR: The Overtopping BReakwater for Energy Conversion (OBREC) is an overtopping type wave energy converter, totally embedded into traditional rubble mound breakwaters.

TL;DR: In this article, the effects of wave nonlinearity on dynamic seabed response in the vicinity of mono-pile foundation is investigated using an integrated model, developed using OpenFOAM, which incorporates both wave model (waves2Foam) and Biot's poro-elastic model.

TL;DR: In this paper, the authors present a comprehensive methodology that addresses climate change-induced coastal erosion at the regional scale O (100 km) by using climate data with high space-time resolution enabled the reconstruction of the shoreline response to crossshore forcing both historically and throughout the twenty-first century.

TL;DR: In this article, an empirical parameterization of wave front slope angle used in the characterization of shoaling and breaking waves in nearshore environment is presented, which is applicable to both the first and second breakpoints for regular wave breaking over sloping and barred beaches.

TL;DR: A large-scale physical model was created in Oregon State University's Large Wave Flume to collect an extensive dataset measuring wave-induced horizontal and vertical forces on an idealized coastal structure as discussed by the authors.

TL;DR: In this paper, the authors presented an experimentally validated, closed-form set of equations for predicting forces on rectangular buildings impinged by nominally unsteady tsunami inundation flows.

TL;DR: The RISC-KIT project as discussed by the authors is a set of open-source and open-access methods, tools and management approaches to reduce risk and increase resilience to lowfrequency, high-impact hydro-meteorological events in the coastal zone (RISC-toolKIT).

TL;DR: In this paper, the authors investigated the applicability of the simplified depth integrated wave transformation model SWASH for wave overtopping estimation of impermeable coastal structures in shallow foreshores.

TL;DR: The authors would like to thank OPW, Ireland for hydrological dataset and ECMWF for METEOROLOGICAL data as mentioned in this paper for rainfall and meteorological data, respectively.

TL;DR: In this article, a three-dimensional integrated numerical model is developed to investigate the wave-induced seabed response around a monopile foundation, where the residual soil behavior under cyclic shearing induced by ocean waves as well as structural rocking motions is investigated.

TL;DR: A Bayesian network approach to integrate the entire risk chain with DRR measures and predicts in real-time, which is useful for decision support in risk management of coastal areas.

TL;DR: In this article, the authors assess the accuracy of 11 existing runup models against field data collected under moderate wave conditions from 11 non-truncated beaches in New South Wales and Queensland, Australia.

TL;DR: In this paper, a battery of pressure transducers was mounted along the external contour of a cylinder placed at half water depth, while four wave gauges were located close to the cylinder and an ultrasonic sensor behind the paddle to measure its displacement.

TL;DR: The highest density contour method is compared to the established inverse first-order reliability method (IFORM) and it is shown that for common probability distributions the two methods yield similarly shaped contours.

TL;DR: In this article, the authors present a methodology for forecasting shoreline change over annual time-scales, including the prediction of the potential impact of storm sequences and the subsequent post-storm recovery.

TL;DR: In this paper, a three-dimensional numerical model based on incompressible Reynolds averaged Navier-Stokes equations was used to investigate flow and scour/backfilling around a vertical pile exposed to waves.

TL;DR: In this paper, a fully coupled (hydrodynamic and morphologic) numerical model is presented, and utilized for the simulation of tsunami-induced scour around a monopile structure, representative of those commonly utilized as offshore wind turbine foundations at moderate depths.

TL;DR: In this article, an analysis of the occurrence of storms and their damage intensity is presented, using historical large-scale events from The Middle Ages to the 1960s at case study sites along the coasts of North Norfolk (UK), Charente-Maritime and Vendee (France); Cinque Terre-Liguria coast (Italy); Emilia-Romagna coast and Ria Formosa (Portugal).

TL;DR: In this paper, the hydrodynamic behavior of a dual pontoon floating breakwater (DPFB) when attached to one or more rows of plane net by using physical and numerical models is investigated.

TL;DR: In this paper, the authors used smoothed particle hydrodynamics (SPH) to compute tsunami wave loads on bridge superstructures using mesh-free methods, which can be used for designing the bridge super-structures at the coastal areas.

TL;DR: In this paper, the authors used tax lot data, Google Street View, and field reconnaissance surveys to classify the buildings in Seaside and to correlate building typologies with existing fragility curves according to the construction material, number of stories, and building seismic design level based on the date of construction.

TL;DR: This paper discusses how the Coastal Risk Assessment Framework (CRAF) has been developed as part of the Resilience Increasing Strategies for Coasts Toolkit (RISC-KIT) and how an integrated modelling approach improves the regional risk assessment of the identified hotspots.

TL;DR: In this paper, the authors investigated the profile response of a mixed sand-gravel deltaic beach (Playa Granada, southern Spain) forced by storm waves from varying directions.
