The propagation of nonlinear surface waves in channels of smoothly variable in space cross section is studied theoretically and by means of numerical computations. The mathematical model describing wave evolution is based on the generalized Korteweg-de Vries equation with additional terms due to spatial inhomogeneity and energy dissipation. Specifically we consider channels of variable depth an...

This study concerns virtual environments for training in operational conditions. The principal developed idea is that these environments are heterogeneous and open multi-agent systems. The MASCARET model is proposed to organize the interactions between agents and to provide them reactive, cognitive and social abilities to simulate the physical and social environment. The physical environment re...

The open-source finite-element system Telemac has been applied to simulate various complex hydrodynamic and morphodynamic situations including waterways, curved channels, recirculating flows and wave-induced littoral transport. In the applications presented here, the sediment transport model is mainly restricted to the transport of non-cohesive sediments, which relies on classical semi-empirica...

Because of the ongoing changing climate, extreme rainfall events’ frequency at global scale is expected to increase, thus resulting in high social and economic impacts. A Meteo/Hydro/Hydraulic forecasting chain combining heterogeneous observational data sources a crucial component for an Early Warning System fundamental asset Civil Protection Authorities correctly predict these events, their ef...

Dissolved oxygen (DO) is one of the most significant environmental indicators water quality. Preservation reasonable DO concentrations essential for a healthy aquatic life. In this research, numerical simulations were discussed using TELEMAC-WAQTEL- O 2 model. Firstly, model was verified by comparing its results to analytical solutions in different 1D and 2D cases considering pulse constant inj...
