Groundwater Pumping Tests

This practical book 'Groundwarer Pumping Tests', details concepts, techniques, field work, case studies, and microcomputer models-information designed to improve accuracy and reliability. The reader is expected to have a working knowledge of hydrogeology or access to books on groundwater geology and hydrology. Too frequently, groundwater pumping test design and analysis ignore well storage capacity, delayed gravity yield, well partial penetration, and aquitard storativity impacts without proving them negligible. As a result, erroneous conclusions are reached concerning aquifer system hydraulic characteristics, boundaries, and discontinuities. Pumping test data often is filtered arbitrarily without adequate justification in attempts to match inappropriate aquifer models and field conditions. Antecedent water level trends and water level adjustments for changes in barometric pressure and surface water stages frequently are ignored in calculating drawdown and recovery. Finally, manual graphic analysis supplemented with microcomputer programs is, to an excessive extent, being replaced by fully automatic microcomputer analysis without critical examination of interpretative methods in program algorithms and their limitations. This book will focus needed attention on the facets mentioned above.

This practical new book details concepts, techniques, field work, case studies, and microcomputer models-information designed to improve accuracy and reliability.

New!

This book contains the results and findings of the advanced research carried out in a pilot area with a thorough investigation of the structure and functioning of an aquifer in a granitic formation. It characterizes the hard rock aquifer system and examines its properties and behavior as well as systematically details the geophysical, geological and remote sensing applications to conceptualize such an aquifer system.

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 .

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

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.

Groundwater Resource Development describes the basic steps involved in the development of a groundwater resource in the search for productive aquifers. This book discusses groundwater exploration, construction and testing of water wells, water quality and pollution considerations, and groundwater management. This text is comprised of 10 chapters and begins by presenting the steps in the evaluation, development, and management of an aquifer for water supply. The reader is then introduced to the fundamentals of groundwater, with emphasis on their origin and occurrence as well as the influence of porosity and permeability on groundwater accumulation, migration, and distribution. The chapters that follow focus on groundwater exploration, assessment of aquifer recharge and potential well yield, and factors affecting the quality of groundwater. The issues to be considered in well design and construction are also highlighted, along with aquifer hydraulics and pumping tests, groundwater pollution, and optimum management of groundwater resources. This text concludes with a chapter on techniques used in modeling the response of a groundwater reservoir. This book will be of value to geologists, civil engineers, environmental scientists, mathematicians, chemists, water well contractors, and others involved in the profession of water engineering.

Groundwater Resources: Investigation and Development is a 13-chapter text that presents in a logical structure the various useful techniques for groundwater investigations. The introductory chapters deal with the general concepts of hydrology, types of aquifers and groundwater environments, and geographic and geologic topographic maps. These topics are followed by considerable chapters on groundwater investigation techniques, including geophysical and geochemical methods, drilling and isotope techniques, exploration, and pumping tests. The advantages and limitations of these techniques are examined. The discussion then shifts to interpretation and utilization of water level measurements and spring flow. The concluding chapters are devoted to determining the three boundaries enclosing the groundwater systems, namely, the fixed, movable, and arbitrary boundaries. These chapters also look into the principles of groundwater balances and groundwater reserves.

The book provides an elaborate treatment of groundwater prospecting and management covering remote sensing, geological–geophysical cum hydrogeological studies, exploration (geological and geophysical), development (well logging techniques, pump test, its analysis and applications in well design), contamination (pollution of groundwater) and regulatory legislations regarding groundwater utilization under one cover. The book presents an elucidation of fundamental and theoretical background of each technique supported by necessary illustrative examples and exclusive case studies. It is a text-cum-reference book not only for students, research scholars and practicing earth scientists but also for practicing civil and agricultural engineers working in the application of groundwater resources, engaged in its exploration, development, contamination, legislation and management. The general readers can also refer the book for understanding the groundwater domain for adequate knowledge, as groundwater resources are essential life support commodity which is replenishable but not inexhaustible.
