This work studies the large scale hydraulic-hydrological modeling of hydrographic networks and the optimal integration of their multi-source observability. The growing wealth of information in data sets brought by hydrometeorology and high resolution

In this work we study some numerical methods for free surface shallow water flows. On one hand, we are interested in non-hydrostatic shallow water models which take into account dispersive effects. On the other hand, we study the shallow water model

In this thesis, we study some non-dispersive conservative regularisations for the scalar conservation laws and also for the barotropic Euler system. Those regularisations are obtained inspired by a regularised Saint-Venant system introduced by Clamon

Développement et analyse de schémas numériques préservant les régimes asymptotiques de diffusion linéaire et non linéaire

Autor: Bulteau, Solène

Publikováno v: Mathématiques [math]. Université de Nantes, Faculté des sciences et des techniques, 2019. Français

The aim of this work is to build and analyze schemes able to discretize the solutions of hyperbolic systems of conservation laws endowed with a source term. The main property required here is the preservation of the asymptotic behaviour, in other wor

Transitions compressible-incompressible en mécanique des fluides : interaction vagues-structures et fluides en rotation

Autor: Bocchi, Edoardo

Publikováno v: Differential Geometry [math.DG]. Université de Bordeaux, 2019. English. ⟨NNT : 2019BORD0279⟩

This manuscript deals with compressible-incompressible transitions arising in partial differential equations of fluid mechanics. We investigate two problems: floating structures and rotating fluids. In the first problem, the introduction of a floatin
