Ocean wave breaking is a difficult-to-model oceanographic process, which has implications for extreme wave statistics, the dissipation of wave energy, and air–sea interaction. Numerical methods capable of reliably simulating real-world directionally spread breaking waves are useful for investigating the physics of wave breaking and for the...

A physical description of the flow mechanisms that govern the distribution of the wall-pressure fluctuations over the surface of a serrated trailing edge is proposed. Three main mechanisms that define the variation of turbulent pressure fluctuations across the serrated edge are discussed and semi-empirical models are formulated accordingly....

Nature-based coastal protection is increasingly recognised as a potentially sustainable and cost-effective solution to reduce coastal flood risk. It uses coastal ecosystems such as mangrove forests to create resilient designs for coastal flood protection. However, to use mangroves effectively as a nature-based measure for flood risk reduction...

This paper presents a novel design method to predict fatigue of flood gates due to dynamic wave loading. The accumulation of fatigue damage is predicted probabilistically over the entire lifetime of the structure rather than with a set of normative events. Load events are defined using a joint probability distribution of historical wind and...

Due to an intensification of anthropogenic activities and climate change in recent decades, the hydrological connections and relationships between rivers and lakes have been significantly modified globally. Poyang Lake is one of the largest freshwater lakes globally and is one of the few that remain naturally connected to the Yangtze River....

The application of unsteady incompressible flow phenomenon over the bluff bodies has received the attention of many researchers due to the rich and complex physics underpinning these flows, and thus requiring special attention in their modelling and numerical simulations. The wake that forms at the leeside of the bluff body is of particular...

The rapid development of free and open-access hydrological models and coupling framework tools continues to present more opportunities for coupled model development for improved assessment of floodplain hydrology. In this study, we set up an Upper Zambezi hydrological model and a fully spatially hydrological-hydrodynamic coupled model for the...

Groundwater is a primary source of freshwater provisions all around the world. Due to its limited availability, water has become a precious entity nowadays. The future accessibility of groundwater is endangered due to its massive exploitation, particularly in the irrigation sector. Therefore, the current study was conducted to assess the...

We perform simulations of random seas based on narrow-banded spectra with directional spreading. Our wavefields are spatially homogeneous and nonstationary in time. We truncate the spectral tail for the initial conditions at different cutoff wavenumbers to assess the impact of the spectral tail on the kurtosis and spectral evolution. We...

Estuarine sediment dynamics involves estuarine hydrodynamics, sediment transport, and morphology, and strongly influence ecosystem dynamics and sustainability. In the current geological epoch, referred to as the Anthropocene, human activities are exerting increasing impacts on the environment on all scales, changing hydrodynamics, sediment...

Estuaries are partially enclosed water bodies where river water mixes with sea water. Estuaries provide important ecological functions which are strongly regulated by estuarine hydrodynamics and sediment dynamics, and also by human interventions. Sustainable management of such systems therefore requires a thorough understanding of the interplay...

In this thesis we study the Symmetric Exclusion Process (SEP) and the Discrete Gaussian Free Field (DGFF) on compact Riemannian manifolds. In particular, we obtain the hydrodynamic limit and the equilibrium fluctuations of SEP and we show that the DGFF converges to its continuous counterpart. To define these discrete models, we construct grids...

Deltas are prograding landforms that exist at the interface between rivers and open water systems (marine or lake) and are formed by the deposition of great loads of fluvial sediments. Depending on the influence of the dominant process, deltas can be classified as river-, tide-, or wave-dominated and they will display distinct morphologies ...

To improve the energy density and directional spectra computed with the SWAN model for the North Sea, a data-driven model is trained to correct the SWAN spectra. After training of the data-driven model on a year of observed and modelled data, the energy density and directional spectrum are corrected for three locations in the North Sea. When...

The Coastal Dynamics conference series advances the community's understanding of coastal processes, in terms of science, engineering and management, spanning a variety of scales and environments including sandy, rocky and muddy coasts, inlets and estuaries. The Coastal Dynamics 2021 conference was the nineth conference in the series hosted by...

Wind waves propagating in the coastal zone, are subject to various changes associated primarily with the impact of nonlinear and dissipative processes. Wave transformation leads to change in the shape of wave spectrum. Sometimes, the major peak frequency shifts to the low-frequency region and so-called “frequency downshifting” are observed. It...

Various properties of wind-generated waves in coastal regions are significantly different from those in deep water regions. The differences are largely due to the influence of bathymetry, which is more pronounced in shallower water. In general, deep water waves are considered a Gaussian random process with only minor discrepancies between the...

As surface waves propagate from deep water toward shallow coastal areas, their ensuing transformation is due to the influence of bathymetry and several important phenomena, such as refraction, shoaling ,and nonlinear effects. Nonlinear wave models based on the classical Boussinesq equation(Peregrine, 1967)have evidenced good performance in...

Low-lying coastal areas can be very vulnerable to extreme storms inducing overtopping and flood events with severe socioeconomic consequences. Also, the associated risk is expected to increase due to sea level rise and coastal population growth. Under this threat, early warning systems (EWS) are a crucial tool for coastal planning and management...

In the past decade, observations in the German estuaries such as the rivers Elbe and Weser show increasingly serious damage to bank protection structures (groins and revetments). This damage is caused mainly by waves induced by the passing of big container ships in the shallow and narrow maritime waterways. These ship-induced 3D wave fields...
