Book Description
This series of five volumes proposes an integrated description of physical processes modeling used by scientific disciplines from meteorology to coastal morphodynamics. Volume 1 describes the physical processes and identifies the main measurement devices used to measure the main parameters that are indispensable to implement all these simulation tools. Volume 2 presents the different theories in an integrated approach: mathematical models as well as conceptual models, used by all disciplines to represent these processes. Volume 3 identifies the main numerical methods used in all these scientific fields to translate mathematical models into numerical tools. Volume 4 is composed of a series of case studies, dedicated to practical applications of these tools in engineering problems. To complete this presentation, volume 5 identifies and describes the modeling software in each discipline.

Book Description
L'objectif de cette thèse est le développement et la validation d'un outil numérique permettant d'évaluer la performance d'un ouvrage de décantation. L'approche Euler-Lagrange est retenue pour la modélisation de l'écoulement et du transport solide. De nouvelles conditions d'interaction particule/paroi permettent de restreindre le dépôt aux zones présentant des caractéristiques géométriques et hydrodynamiques favorables. Le modèle numérique est confronté à quatre jeux de données expérimentales. L'ensemble de ces expérimentations permettent d'investiguer une large gamme des paramètres représentatifs de l'écoulement et du transport solide. La comparaison des résultats numériques et expérimentaux permet de conclure sur la capacité du modèle à prévoir l'abattement des particules dans un ouvrage de décantation avec une précision de l'ordre de 5 pourcents lorsque les dépôts ont lieu sur l'ensemble du fond et de 10 pourcents dans le cas de dépôts localisés dans des zones préférentielles.

Book Description
This book gathers a collection of extended papers based on presentations given during the SimHydro 2017 conference, held in Sophia Antipolis, Nice, France on June 14–16, 2017. It focuses on how to choose the right model in applied hydraulics and considers various aspects, including the modeling and simulation of fast hydraulic transients, 3D modeling, uncertainties and multiphase flows. The book explores both limitations and performance of current models and presents the latest developments in new numerical schemes, high-performance computing, multiphysics and multiscale methods, and better interaction with field or scale model data. It gathers the lastest theoretical and innovative developments in the modeling field and presents some of the most advance applications on various water related topics like uncertainties, flood simulation and complex hydraulic applications. Given its breadth of coverage, it addresses the needs and interests of practitioners, stakeholders, researchers and engineers alike.
