A surrogate model for efficient quantification of uncertainties in multilayer shallow water flows (2021)
Journal Article

In this study, we investigate the implementation of a Proper Orthogonal Decomposition (POD) Polynomial Chaos Expansion (PCE) POD-PCE surrogate model for the propagation and quantification of the uncertainty in hydraulic modelling. The considered mode... Read More about A surrogate model for efficient quantification of uncertainties in multilayer shallow water flows.

Data-driven polynomial chaos expansions for characterization of complex fluid rheology: Case study of phosphate slurry (2021)
Journal Article

Mine transportation through hydraulic pipelines is increasingly used by various industries around the world. In Morocco, this has been implemented for the case of phosphate transportation. This allows to increase the production and reduce the transpo...

A boundary element method formulation based on the Caputo derivative for the solution of the diffusion-wave equation (2021)
Journal Article

A boundary element method formulation is developed and validated through the solution of problems governed by the diffusion-wave equation, for which the order of the time derivative, say α, ranges in the interval (1, 2). This fractional time derivati... Read More about A boundary element method formulation based on the Caputo derivative for the solution of the diffusion-wave equation.

An enriched Galerkin-characteristics finite element method for convection-dominated and transport problems (2021)
Journal Article

We propose an enriched Galerkin-characteristics finite element method for numerical solution of convection-dominated problems. The method uses the modified method of characteristics for the integration of the total derivative in time, combined with t...

Journal Article

Non-intrusive polynomial chaos methods for uncertainty quantification in wave problems at high frequencies (2021)
Journal Article

Numerical solutions of wave problems are often influenced by uncertainties generated by a lack of knowledge of the input values related to the domain data and/or boundary conditions in the mathematical equations used in the modeling. Conventional met... Read More about Non-intrusive polynomial chaos methods for uncertainty quantification in wave problems at high frequencies.

A Computational Model for Simulation of Shallow Water Waves by Elastic Deformations in the Topography (2021)
Journal Article

We propose a coupled model to simulate shallow water waves induced by elastic deformations in the bed topography. The governing equations consist of the depth-averaged shallow water equations including friction terms for the water freesurface and the...
