Book Description
A definitive guide for accurate state-of-the-art modelling of free surface flows Understanding the dynamics of free surface flows is the starting point of many environmental studies, impact studies, and waterworks design. Typical applications, once the flows are known, are water quality, dam impact and safety, pollutant control, and sediment transport. These studies used to be done in the past with scale models, but these are now being replaced by numerical simulation performed by software suites called “hydro-informatic systems”. The Telemac system is the leading software package worldwide, and has been developed by Electricité de France and Jean-Michel Hervouet, who is the head and main developer of the Telemac project. Written by a leading authority on Computational Fluid Dynamics, the book aims to provide environmentalists, hydrologists, and engineers using hydro-informatic systems such as Telemac and the finite element method, with the knowledge of the basic principles, capabilities, different hypotheses, and limitations. In particular this book: presents the theory for understanding hydrodynamics through an extensive array of case studies such as tides, tsunamis, storm surges, floods, bores, dam break flood waves, density driven currents, hydraulic jumps, making this a principal reference on the topic gives a detailed examination and analysis of the notorious Malpasset dam failure includes a coherent description of finite elements in shallow water delivers a significant treatment of the state-of-the-art flow modelling techniques using Telemac, developed by Electricité de France provides the fundamental physics and theory of free surface flows to be utilised by courses on environmental flows Hydrodynamics of Free Surface Flows is essential reading for those involved in computational fluid dynamics and environmental impact assessments, as well as hydrologists, and bridge, coastal and dam engineers. Guiding readers from fundamental theory to the more advanced topics in the application of the finite element method and the Telemac System, this book is a key reference for a broad audience of students, lecturers, researchers and consultants, right through to the community of users of hydro-informatics systems.

ISBN:
Category : Science
Languages : en
Pages : 686
Book Description
River floodplains represent a most important component of the environment. They play a critical role in the routing and storage of floodwaters and frequently represent unique and valuable habitats. Increasingly, such areas are under pressure form human activity in a wide variety of forms. This volume seeks to outline recent major research developments that have taken place in the study of floodplain processes. The chapters represent the results of recent engineering, geomorphological, hydrological, planning and other specialist developments. The book will contribute to research not only within the specialist research disciplines outlined, but also in the more interdisciplinary challenges facing river management.
UNE METHODE D' ELEMENTS FINIS POUR LES EQUATIONS DE SAINT- VENANT.

Category : Science
Languages : en
Pages : 392
Book Description
Looks at exciting developments in sophisticated numerical analysis techniques in the environmental sciences illustrating the application scope for such techniques. High resolution hydraulic modelling is becoming accepted as a standard research methodology by hydrologists, geomorphologists and engineers. As a consequence of the development of process understanding, numerical analysis techniques and computer power, there is now enormous potential to connect complex flow processes to the landforms they create in a rigorous, quantitative manner that has not hitherto, been possible. This volume provides an integrated coverage of this topic, outlining major research developments that have taken place. It begins with an introductory chapter on hydraulic theory, and then concentrates on high dimensional and high resolution approaches, detailing current research debates in hydraulic modelling. There is comprehensive coverage of application scope for such techniques including flow development, sediment transport, pollutant transport, catchment hydrology and landform development. This readable and accessible book provides an introduction to geomorphology students attempting to familiarise themselves with these exciting developments and also gives researchers invaluable articles illustrating the scope for high resolution hydraulic modelling and the fundamental scientific and philosophical problems raised.

Book Description
Dans ce travail on s'intéresse à la résolution des équations de Saint -Venant par la méthode des éléments finis. Deux tests numériques sont présentés en utilisant deux paires d 'éléments finis : P1NC - P1 et RT0 - P0. Lorsque le systèrne d'équations de Saint-Venant admet une solution analytique, cette solution est comparée avec celle obtenue par la méthode numérique pour montrer la robustesse de ces éléments finis.
