An integrated high-resolution bathymetric model for the Danube Delta system Open
Acting as a buffer between the Danube and the Black Sea, the Danube Delta plays an important role in regulating the hydro-biochemical flows of this land–sea continuum. Despite its importance, very few studies have focused on the impact of …

Preliminary assessment of the environmental impact of NEOM coastal developments on the Northern Red Sea coral reefs Open
In the context of a warming world, annual bleaching events are becoming more likely and threaten coral reefs on a global scale, leading to a growing interest in identifying local-scale thermal refugia. However such shallow reef refugia are…

Multi-scale modelling of the water and sediment fluxes from the Nile Delta to the Suez Canal Open
The Suez Canal holds a pivotal role in global navigation and supply chains by facilitating the movement of goods between the East and West. Around 50 vessels navigate the canal daily. However, a pressing concern threatens its operational s…

Assessing the sensitivity of storm surge simulation to the atmospheric forcing resolutions across the estuary-sea continuum Open
Estuaries are particularly vulnerable to flooding from extreme events such as storm surges, and this vulnerability can be exacerbated by climate change. Numerical models are valuable tools for supporting flood prevention and planning in th…

A Coupled PFEM-DEM Model for Fluid-Granular Flows with Free-Surface Dynamics Applied to Landslides Open
Free surface and granular fluid mechanics problems combine the challenges of fluid dynamics with aspects of granular behaviour. This type of problem is particularly relevant in contexts such as the flow of sediments in rivers, the movement…

Solving the Porous Medium Equation with the eXtreme Mesh deformation approach (X-Mesh) Open
We introduce a new scheme for solving the non-regularized Porous Medium Equation. It is mass conserving and uses only positive unknown values. To address these typically conflicting features, we employ the eXtreme Mesh deformation approach…

The Tempered Finite Element Method Open
In this paper, we propose a new approach -- the Tempered Finite Element Method (TFEM) -- that extends the Finite Element Method (FEM) to classes of meshes that include zero-measure or nearly degenerate elements for which standard FEM appro…

Mechanisms enabling the self-recruitment of passive larvae in the Great Barrier Reef Open
This paper evaluates the conditions experienced by water-born passive larvae of broadcast spawning coral and crown-of-thorn starfish and how they influence self-recruit to their natal reefs in the Great Barrier Reef. The hypothesis that pa…

The discontinuous Galerkin method for river-delta continuum by means of a coupled 1D-2D shallow water model Open
The 1D Saint-Venant equations are widely used in river modeling for engineering applications. The governing equations maybe formulated in several ways. In discrete form, those formulations are not equivalent. Thus, choosing the convenient …

Numerical modelling of navigable rivers: Influence of navigation structures in the Meuse River flow Open
The numerical simulation of navigable rivers is a complex task due to the func- tioning of hydraulic structures that introduces alterations in the river flow dynamics. Therefore modules for simulation of hydraulic works such as weirs and u…

A Delaunay refinement algorithm for the particle finite element method applied to free surface flows Open
This article proposes two contributions to the calculation of free‐surface flows using the particle finite element method (PFEM). The PFEM is based upon a Lagrangian approach: a set of particles defines the fluid and each particle is assoc…

A Multiscale 1D-2D Coupled Model Of The Scheldt Estuary Rivers And The European Continental Shelf Open
This study presents a model for simulating the interaction of river influxes with tidal propagation in region of varying complexity for the Scheldt basin (river, tributaries and estuary) and the European continental shelf. While the domain…

Collapse dynamics of two-dimensional dry and immersed granular columns of elongated grains Open
The collapse dynamics and runout of columns of elongated grains in two dimensions are numerically investigated in dry and immersed conditions, by means of an unresolved finite elements/discrete elements model. The elongated grains are mode…

A split-explicit second order Runge–Kutta method for solving 3D hydrodynamic equations Open
Numerical models of marine hydrodynamics have to deal with processes exhibiting a wide range of timescales. These processes include fast external gravity waves and slower internal fully three-dimensional motions. In order to be both time-e…
