Book Description
Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.
Book Description
LES MILIEUX POREUX SONT LE SIEGE DE TRANSFERTS MULTIPLES QUI PEUVENT ETRE THERMIQUES, HYDRIQUES OU SOLUTAUX. CES PHENOMENES SONT IMPORTANTS DANS L'ETUDE DE LA SURETE DES CENTRES DE STOCKAGES DE DECHETS RADIOACTIFS, AFIN DE PREDIRE L'EVENTUEL RELACHEMENT DES RADIONUCLEIDES HORS DES COLIS. DEVANT DE TELS ENJEUX, IL EST ESSENTIEL DE S'INTERESSER AUX PHENOMENES COUPLES HABITUELLEMENT NEGLIGES PAR RAPPORT AUX EFFETS DIRECTS TELS QUE LA LOI DE FOURIER, LA LOI DE DARCY OU LA LOI DE FICK. LA PREMIERE PARTIE DE CE TRAVAIL CONSISTE A ETABLIR UN MODELE MATHEMATIQUE RIGOUREUX, A PARTIR DE LA THERMODYNAMIQUE DES PROCESSUS IRREVERSIBLES, DES TRANSFERTS SE PRODUISANT DANS UN MILIEU POREUX NON SATURE SUPPOSE INDEFORMABLE. A PARTIR DU SYSTEME DE QUATRE EQUATIONS COUPLEES AUX DERIVEES PARTIELLES OBTENU, UNE MODELISATION NUMERIQUE A ETE REALISEE ET IMPLANTEE DANS LE CODE CALCUL CESAR-LCPC DEVELOPPE AU LABORATOIRE CENTRAL DES PONTS ET CHAUSSEES. L'ACCENT A ETE PORTE SUR L'EQUATION DE TRANSFERT DU SOLUTE SOUS L'INFLUENCE DE LA DIFFUSION MOLECULAIRE, DE LA DISPERSION MECANIQUE ET DE L'EFFET SORET. EQUIVALENT A LA THERMODIFFUSION POUR LES GAZ, L'EFFET SORET TRADUIT L'INFLUENCE DU GRADIENT DE TEMPERATURE SUR LE TRANSPORT DES SOLUTES.

Book Description
This is the first comprehensive introduction to the theory of mass transportation with its many—and sometimes unexpected—applications. In a novel approach to the subject, the book both surveys the topic and includes a chapter of problems, making it a particularly useful graduate textbook. In 1781, Gaspard Monge defined the problem of “optimal transportation” (or the transferring of mass with the least possible amount of work), with applications to engineering in mind. In 1942, Leonid Kantorovich applied the newborn machinery of linear programming to Monge's problem, with applications to economics in mind. In 1987, Yann Brenier used optimal transportation to prove a new projection theorem on the set of measure preserving maps, with applications to fluid mechanics in mind. Each of these contributions marked the beginning of a whole mathematical theory, with many unexpected ramifications. Nowadays, the Monge-Kantorovich problem is used and studied by researchers from extremely diverse horizons, including probability theory, functional analysis, isoperimetry, partial differential equations, and even meteorology. Originating from a graduate course, the present volume is intended for graduate students and researchers, covering both theory and applications. Readers are only assumed to be familiar with the basics of measure theory and functional analysis.

Book Description
Honoring the contributions of one of the field's leading experts, Lu Ting, this indispensable volume contains important new results at the cutting edge of research. A wide variety of significant new analytical and numerical results in critical areas are presented, including point vortex dynamics, superconductor vortices, cavity flows, vortex breakdown, shock/vortex interaction, wake flows, magneto-hydrodynamics, rotary wake flows, and hypersonic vortex phenomena.The book will be invaluable for those interested in the state of the art of vortex dominated flows, both from a theoretical and applied perspective.Professor Lu Ting and Joe Keller have worked together for over 40 years. In their first joint work entitled ?Periodic vibrations of systems governed by nonlinear partial differential equations?, perturbation analysis and bifurcation theory were used to determine the frequencies and modes of vibration of various physical systems. The novelty was the application to partial differential equations of methods which, previously, had been used almost exclusively on ordinary differential equations. Professsor Lu Ting is an expert in both fluid dynamics and the use of matched asymptotic expansions. His physical insight into fluid flows has led the way to finding the appropriate mathematical simplications used in the solutions to many difficult flow problems.
