Computational Methods In Water Resources Xiii Computational Methods For Subsurface Flow And Transport

The two-volume set presents recent developments and applications of computational methods in surface and subsurface hydrology, including mathematical and numerical modelling of physical, biological and chemical processes related to water, as well as other associated topics such as algorithmic methodologies, parameter estimation and software development."

These volumes contain the proceedings of CMWR2002, which was hosted by the Faculty of Civil Engineering & Geosciences at Delft University of Technology. The interest in this meeting was truly overwhelming: around 230 papers from leading scientists were submitted and accepted for publication in the proceedings. The actual scope of the meeting was much broader than the title "Computational Methods in Water Resources" might suggest. Not only traditional hydrological topics like surface water and groundwater hydrology were covered, but also modern topics like coupled reactive transport, multiphase flow, pore-scale network modeling, remediation techniques, optimization, groundwater-surface water interactions and data assimilation. A quick glance through the Table of Contents of these two volumes immediately shows the richness of the material presented during the four days of the conference. New conceptual models, experimental methods, upscaling techniques and parameter estimation procedures were introduced. Nevertheless, the emphasis was still on the development of new accurate and robust computational techniques.

Computational Methods in Subsurface Flow explores the application of all of the commonly encountered computational methods to subsurface problems. Among the problems considered in this book are groundwater flow and contaminant transport; moisture movement in variably saturated soils; land subsidence and similar flow and deformation processes in soil and rock mechanics; and oil and geothermal reservoir engineering. This book is organized into 10 chapters and begins with an introduction to partial differential and various solution approaches used in subsurface flow. The discussion then shifts to the fundamental theory of the finite element method, with emphasis on the Galerkin finite element method and how it can be used to solve a wide range of subsurface problems. The subjects treated range from simple problems of saturated groundwater flow to more complex ones of moisture movement and multiphase flow in petroleum reservoirs. The chapters that follow focus on fluid flow and mechanical deformation of conventional and fractured porous media; point and subdomain collocation techniques and the boundary element technique; and the applications of finite difference techniques to single- and multiphase flow and solute transport. The final chapter is devoted to other alternative numerical methods that are based on combinations of the standard finite difference approach and classical mathematics. This book is intended for senior undergraduate and graduate students in geoscience and engineering, as well as for professional groundwater hydrologists, engineers, and research scientists who want to solve or model subsurface problems using numerical techniques.

Part of a two volume set, this text contains the proceedings of the 12th Conference on Computational Methods in Water Resources, which was held in Greece in July 1998. It includes recent ideas in the development and applications of computational techniques to subsurface hydrology.

Numerical methods provide a powerful and essential tool for the solution of problems of water resources. This book gives an elementary introduction to the various methods in current use and demonstrates that different methods work well in different situations and some problems requirecombinations of methods. It is essential to know something of all of them in order to make a reasoned judgement of current practice. Their applications are discussed and more specialised versions are outlined along with many references making this an invaluable, comprehensive coverage of thefield.
