Analytical Groundwater Modeling

Bol

This book provides a detailed description of how Python can be used to give insight into the flow of groundwater based on analytic solutions. Starting with simple problems to illustrate the basic principles, complexity is added step by step to show how one-dimensional and two-dimensional models of one or two aquifers can be implemented. Steady and transient flow problems are discussed in confined, semi-confined, and unconfined aquifers that may include wells, rivers, and areal recharge. Special consideration is given to coastal aquifers, including the effect of tides and the simulation of interface flow. Application of Python allows for compact and readable code, and quick visualization of the solutions. Python scripts are provided to reproduce all results. The scripts are also available online so that they can be altered to meet site-specific conditions. This book is intended both as training material for the next generation of university students and as a useful resource for practitioners. A primer is included for those who are new to Python or as a refresher for existing users.

This new book includes four analytical microcomputer progRAMs -on two diskettes-for quick easy simulation and graphing of uncomplicated two-dimensional groundwater flow and containment migration situations. Program operation, concepts, techniques, and methods are described in detail. The basic programs feature simulations of the following features: containment source areas and plumes, production and injection wells, drains, and mines. A graphics subprogram displays drawdown and concentration graphs and contour maps. Basic requirements are an IBM-PC or compatible computer with 256K RAM; a high resolution (640 x 200) monitor (monochrome mode); an IBM Color Graphics Adapter (CGA), IBM Enhanced Graphics Adapter (EGA), IBM Video Graphics Array (VGA) or IBM Multi-Color Graphics Array (MCGA), Hercules Color card (not Hercules Graphics card-though there are inexpensive CGA emulation programs on the market for the Hercules Graphics card) or equivalent; a dot-matrix printer; and IBM-PC DOS Version 2.1 or compatible.
