New! A practical, easy-to-use reference for the design and analysis of groundwater pumping and slug tests Aquifer Testing: Design and Analysis of Pumping and Slug Tests is a complete design and analysis reference emphasizing practical solutions for engineers, scientists, consultants, and students knowledgeable in basic ground water theory. T

This book, designed as a handbook, provides a systematic treatment of analytical solutions describing groundwater flow during aquifer tests. The book integrates the majority of known solutions from well hydraulics and subsurface flow theory, starting with pioneering work from the early 20th century up to the most recent publications in scientific journals. The book includes about 300 transient solutions covering a wide range of aquifer test scenarios and hydrogeological conditions. All the solutions have been thoroughly tested and implemented in the multifunctional ANSDIMAT software. The book comprises three parts and is supplemented by appendices. The first part of the book is dedicated to basic analytical relationships referring to pumping tests with constant discharge rate. Conceptual models describe confined, unconfined, confined–unconfined, inhomogeneous, and fracture-porous aquifers, as well as leaky aquifers and multi-layer aquifer systems. Complicating factors such as flow boundaries, aquifer anisotropy, non-uniform aquifer thickness, partial well penetration, wellbore storage and skin, the effect of capillary forces are also considered. The second part focuses on complex pumping test settings and well system configurations. Analytical solutions are presented for pumping from a horizontal or inclined well, constant-head tests, multi-well variable-discharge tests, simultaneous pumping from adjacent aquifers and dipole flow tests. Detailed descriptions are given for slug and recovery tests. The third part of the book contains algorithms for evaluating hydraulic characteristics using analytical and graphical methods, and is supplemented by the ANSDIMAT tool. This software includes solutions for some practical engineering-hydrogeological problems, in particular, the assessment of aquifer characteristics by data on groundwater level monitoring and the evaluation of water inflow into open pits. The book is supplemented with appendices in which hydrogeologists can find a vast body of useful information including mathematical descriptions of the majority of analytical functions used in the book, their plots and possible approximations. Audience: The book is useful for hydrogeologists (students, engineers and researchers) engaged in groundwater flow studies, aquifer test analysis, environmental geologists and civil engineers. Experts in water flow numerical modeling and programmers developing software for aquifer tests will find valuable information in this book, which can also be used for educational and research purposes.

This document is intended as a primer, describing the process for the design and performance of an “aquifer test” (how to obtain reliable data from a pumping test) to obtain accurate estimates of aquifer parameters. It is intended for use by those professionals involved in characterizing sites which require corrective action as well as those which are proposed for ground water development, agricultural development, industrial development, or disposal activities. The goal of the document is to provide the reader with a complete picture of all of the elements of aquifer (pumping) test design and performance and an understanding of how those elements can affect the quality of the final data.

ANSI/ASCE/EWRI 70-19 provides guidelines for estimating the hydraulic properties of groundwater systems by inverse numerical modeling of aquifer pumping tests.

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)
