This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the user's manual of FEMWATER, A Three-dimensional Finite Element Computer Model for Simulating Density-Dependent Flow and Transport The intended users of the manual will have a wide range of technical experience and have different needs that the model and documentation will fulfill. Sophisticated users will find descriptions of the numerical techniques and a complete set of governing equations that form the theoretical basis of the model. The casual users will find examples of several types of problems that will include their type of application. FEMWATER is a modern implementation of the two older models, 3DFEMWATER (flow) and 3DLEWASTE (transport). FEMWATER was formed by combining the two codes into a single coupled flow and transport model. The improvements implemented in FEMWATER are numerous. First, the entire program structure was changed to allow its integration into the Department of Defense Groundwater Modeling System (GMS). The GMS contains a state-of-the-art graphical user environmental that allows efficient model setup and visualization. Second, a series of new solvers were added to replace the previously used block iterative solver. The new solvers allow an arbitrary node numbering scheme that enables easier graphical user interface connections and still provide improved computational efficient. Their, density-driven (salinity) transport capability was added to allow salinity intrusion studies in coastal aquifers. This required the coupling of flow and transport within a common model, which is the last major improvement.

This book was released on 2010-01-18 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers. The basic approach of this book is to accurately describe the underlying physics of groundwater flow and solute transport in heterogeneous porous media, starting at the microscopic level, and to rigorously derive their mathematical representation at the macroscopic levels. The well-posed, macroscopic mathematical models are formulated for saturated, single phase flow, as well as for unsaturated and multiphase flow, and for the transport of single and multiple chemical species. Numerical models are presented and computer codes are reviewed, as tools for solving the models. The problem of seawater intrusion into coastal aquifers is examined and modeled. The issues of uncertainty in model input data and output are addressed. The book concludes with a chapter on the management of groundwater resources. Although one of the main objectives of this book is to construct mathematical models, the amount of mathematics required is kept minimal.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the edited proceedings of the Fifth International Conference on Finite Elements in Water Resources, held at the University of Vermont, USA in June 1984. This Conference cont inues the successful series started at Princeton University in 1976, followed by the Conference in Imperial College, London, UK in 1978, the third Conference at the University of Mississippi, USA in 1980 and the fourth at the University of Hannover, Germany in 1982. The objective of this Conference is to provide engineers and scientists interested in water resources with the state-of-t- art on finite element modelling. The Proceedings review the basic theory and applications of the technique in groundwater and seepage, transport phenomena, viscous flow, river, lake and ocean modelling. The fundamentals of the numerical techniques employed in finite elements are also discussed. Many applications illus trate the versatility and generality of the Finite Element Method for the simulation of a wide range of problems in water resources. More recent schemes, in particular, boundary elements, are also presented, together with a series of advanced numerical techniques. The Conference has become an internationally accepted forum for the presentation of new developments of finite elements in water resources techniques. Because of this, a large number of abstracts were submitted to the Organizing Committee and it is our only reg ret that it was impossible to accept all these contributions. The overwhelming response to our Call for Papers has ensured the high quality of these proceedings.

Book excerpt: The finite-element program FEMFLOW3D consists of the main program, a simple driver, and a set of subroutines which perform model calculations. The source code for the program is written in the ANSI x3.9-1978 FORTRAN standard. Two compiler specifications must be included when compiling the source code: (1) The compiler must accept "ENTRY" statements that have a different argument list than the argument list for the main subroutine call, and (2) the internal variables within the subroutines must be saved.
