The Design, Performance, and Analysis of Slug Tests


Book Description

The slug test is currently the most common method for the in situ estimation of hydraulic conductivity at sites of suspected groundwater contamination. However, inappropriate procedures in one or more phases of a slug test can introduce considerable error into the resulting parameter estimates. This book remedies this problem by answering virtually every question regarding the design, performance, and analysis of slug tests. This is the first book to provide detailed information on the practical aspects of the methodology of slug tests. All major analysis methods are described in The Design, Performance, and Analysis of Slug Tests. Each analysis method is outlined in a step-by-step manner and illustrated with a field example. The major practical issues related to the field application of each technique are also discussed. This book will help the reader get more reliable parameter estimates from slug tests and increase the utility of slug test data.




The Design, Performance, and Analysis of Slug Tests


Book Description

The slug test can provide valuable information for hydrogeologic investigations ranging from assessments of sites of groundwater contamination to the monitoring of well deterioration through time. Inappropriate procedures in one or more phases of a test program, however, can introduce considerable error into the resulting parameter estimates. The Design, Performance, and Analysis of Slug Tests, Second Edition remedies that problem by explaining virtually all there is to know regarding the design, performance, and analysis of slug tests. The first edition has become the standard reference for all aspects of slug tests; this revised edition updates the earlier material and expands the topical coverage with new developments that have come to the fore in the intervening years between editions. Features: Describes and demonstrates the eight key steps for the performance and analysis of slug tests Presents new methods for the analysis of tests in unconfined aquifers and in highly permeable settings Expands topical coverage of LNAPL baildown tests and slug tests in small diameter wells Includes numerous flow charts that illustrate easy-to-use strategies for selection of analysis methods, and field examples demonstrate how each method should be used to get the most out of test data Offers straightforward practical guidelines that summarize the major points of each chapter Written for practicing groundwater consultants and engineers, The Design, Performance, and Analysis of Slug Tests, Second Edition will enable readers to get more reliable information from slug tests and increase the utility of this widely-used field method.

Groundwater Science


Book Description

Groundwater Science, 2E, covers groundwater's role in the hydrologic cycle and in water supply, contamination, and construction issues. It is a valuable resource for students and instructors in the geosciences (with focuses in hydrology, hydrogeology, and environmental science), and as a reference work for professional researchers. This interdisciplinary text weaves important methods and applications from the disciplines of physics, chemistry, mathematics, geology, biology, and environmental science, introducing you to the mathematical modeling and contaminant flow of groundwater. New to the Second Edition:. New chapter on subsurface heat flow and geothermal systems. Expanded content on well construction and design, surface water hydrology, groundwater/ surface water interaction, slug tests, pumping tests, and mounding analysis.. Updated discussions of groundwater modeling, calibration, parameter estimation, and uncertainty. Free software tools for slug test analysis, pumping test analysis, and aquifer modeling. Lists of key terms and chapter contents at the start of each chapter. Expanded end-of-chapter problems, including more conceptual questions. Two-color figures. Homework problems at the end of each chapter and worked examples throughout. Companion website with videos of field exploration and contaminant migration experiments, PDF files of USGS reports, and data files for homework problems. PowerPoint slides and solution manual for adopting faculty.







Aquifer Hydraulics


Book Description

Aquifere (Grundwasserleiter) sind die Hauptquelle für Trinkwasser auf der ganzen Welt, und diese Wasserreserven vor Erschöpfung oder Verunreinigung zu schützen ist ein zentrales Anliegen. Dieses Buch kann als Lehrbuch oder Nachschlagewerk genutzt werden und bietet eine umfassende Einführung in die Hydraulik von wasserführenden Schichten und das Messen von deren Parametern. Es vermittelt Schritt für Schritt einen Einblick in Auslegung, Durchführung und Analyse einer kompletten Reihe von Tests, die üblicherweise verwendet werden. Es werden detaillierte Anwendungsbeispiele zu einer breiten Palette von Methoden zur Quelluntersuchung gegeben sowie praktische Anweisungen zur Analyse der gewonnenen Daten. Ein unverzichtbares, praxisorientiertes Nachschlagewerk für Experten und Studenten, die sich mit dem Problem der Grundwasserqualität und -quantität beschäftigen. (01/98)







Aquifer Characterization Techniques


Book Description

This book presents an overview of techniques that are available to characterize sedimentary aquifers. Groundwater flow and solute transport are strongly affected by aquifer heterogeneity. Improved aquifer characterization can allow for a better conceptual understanding of aquifer systems, which can lead to more accurate groundwater models and successful water management solutions, such as contaminant remediation and managed aquifer recharge systems. This book has an applied perspective in that it considers the practicality of techniques for actual groundwater management and development projects in terms of costs, technical resources and expertise required, and investigation time. A discussion of the geological causes, types, and scales of aquifer heterogeneity is first provided. Aquifer characterization methods are then discussed, followed by chapters on data upscaling, groundwater modelling, and geostatistics. This book is a must for every practitioner, graduate student, or researcher dealing with aquifer characterization .
