Journal ArticleDOI
TL;DR: In this article, the impact of sea level rise on extreme water levels is investigated using a numerical model that covers the entire North Sea, but has its highest spatial resolution in the northern part of the German Bight.

Journal ArticleDOI
TL;DR: In this article, the impact of a tsunami bore on simplified bridge piers was investigated using smoothed particle hydrodynamics (SPH) method. But the authors did not consider the effects of bridge pier shape and orientation on free surface evolution and hydrodynamic loading.

Journal ArticleDOI
TL;DR: In this article, a copula-based approach is presented for modeling the joint distribution derived from almost six years of sea levels and waves at a site suffering from coastal flooding at a particular simplified application case is described for the Ravenna coast (Italy).

Journal ArticleDOI
TL;DR: In this article, 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, was presented to simulate the morphodynamic response of pure gravel beaches and barriers to storms.

Journal ArticleDOI
TL;DR: In this paper, the influence of vegetation density and biomass on wave attenuation in salt marshes was evaluated and shown that higher vegetation density leads to higher attenuation rates for both species.

Journal ArticleDOI
TL;DR: In this paper, the authors proposed three survival modes to ensure the survivability of the spar floating wind turbine under extreme conditions, and the results from the tests and the numerical simulations were compared in the towing tank of MARINTEK, Norway.

Journal ArticleDOI
TL;DR: In this article, a coupled wave-current-sediment transport beach profile model is used to simulate cross-shore sandbar evolution on the time scale from days to months comprising both rapid offshore and slow onshore migrations.

Journal ArticleDOI
TL;DR: In this paper, a 2D diffusive weakly-compressible Smoothed Particle Hydrodynamics (SPH) model is proposed to simulate wave loads and hydraulic characteristics at perforated breakwaters.

Journal ArticleDOI
TL;DR: In this article, large-scale experiments on the pressure exerted on a tide wall due to the impact, reflection and overflow of tsunami inundation flow were carried out to investigate the characteristics of the pressure and the flow in front of the tide wall in the bore impact, initial reflection, and quasi-steady-state phases.

Journal ArticleDOI
TL;DR: The target of the paper is to provide a general framework for the multivariate assessment of the risk of failure by using a structural approach, and to compare the structural-risk approach proposed here with the strategies adopted in previous papers.

Journal ArticleDOI
TL;DR: In this paper, a two-phase flow CFD model based on the Reynolds-Averaged Navier-Stokes (RANS) equations coupled with the level set method (LSM) and k−−-ω turbulence model is used to simulate spilling breakers over a sloping bed.

Journal ArticleDOI
TL;DR: In this article, an improved hydrological and hydrodynamic modeling framework has been developed for the Houston Ship Channel (HSC) and Galveston Bay to serve as a quantitative testbed for evaluating coupled hurricane storm surge and rainfall-runoff.

Journal ArticleDOI
TL;DR: In this paper, a volume of fluid method for coastal structures under the influence of normal incident irregular wave fields is proposed and validated against a multiple of experimental data sets for two dimensional coastal problems.

Journal ArticleDOI
TL;DR: In this paper, an extensive experimental campaign is presented to explain the edge scour process in current and combined irregular waves and current, as well as tidal current, showing a local increase in the flow velocities and bed shear stresses leading to increased sediment transport and scour.

Journal ArticleDOI
TL;DR: In this article, a semi-analytical theory of water wave propagation through vegetation developed by Mei, Chan and Liu (2014) is extended to examine the cases where the vegetated area has a finite extent.

Journal ArticleDOI
TL;DR: In this article, the authors present a modelling framework which integrates geological, engineering and economic approaches for assessing the climate change driven economic risk to coastal developments, which is necessary to enable risk assessments which are now required by emerging risk based coastal zone management/planning frameworks.

Journal ArticleDOI
TL;DR: In this article, the authors investigated the near surface flow and transport potential of three artificial structure designs: a single ridge, a double ridge and a dyke, and the results suggest that the double ridge structure is the most resilient to aeolian erosion.

Journal ArticleDOI
TL;DR: In this paper, a Bayesian Network approach was used to determine Local Hazard Indicators (LHIs) from a hindcasted storm with use of a nearshore morphodynamic model, XBeach, and coupling these LHIs and building characteristics to the observed damages.
