This book describes microcomputer programs which can be used to simulate or analyse water production well and aquifer discharge test data. Computer graphics are used to help visualise the data, and output to plotters is also catered for. Simple confined aquifers, leaky confined aquifers, unconfined aquifers and a variety of boundary conditions are dealt with. The book and the microcomputer programs it describes will allow the reader to apply very flexible computer techniques to the analysis of his well and aquifer discharge test data. The speed of the microcomputer analyses will give the user the opportunity of looking at his data in more ways than he would otherwise be able to, thus giving insights into the data that would not otherwise be possible. The simulation programs permit the production of type curve data, which can then be used in comparison with the real data, or used in becoming familiar with the operation of the analysis programs. Although primarily intended for practicing hydrogeologists and universities teaching hydrogeology, this book would also be of interest to anyone having an interest in the effects of groundwater extraction. The programs will run on IBM PCs and compatibles with colour graphics.

Methods and guidelines for developing and using mathematical models Turn to Effective Groundwater Model Calibration for a set of methods and guidelines that can help produce more accurate and transparent mathematical models. The models can represent groundwater flow and transport and other natural and engineered systems. Use this book and its extensive exercises to learn methods to fully exploit the data on hand, maximize the model's potential, and troubleshoot any problems that arise. Use the methods to perform: Sensitivity analysis to evaluate the information content of data Data assessment to identify (a) existing measurements that dominate model development and predictions and (b) potential measurements likely to improve the reliability of predictions Calibration to develop models that are consistent with the data in an optimal manner Uncertainty evaluation to quantify and communicate errors in simulated results that are often used to make important societal decisions Most of the methods are based on linear and nonlinear regression theory. Fourteen guidelines show the reader how to use the methods advantageously in practical situations. Exercises focus on a groundwater flow system and management problem, enabling readers to apply all the methods presented in the text. The exercises can be completed using the material provided in the book, or as hands-on computer exercises using instructions and files available on the text's accompanying Web site. Throughout the book, the authors stress the need for valid statistical concepts and easily understood presentation methods required to achieve well-tested, transparent models. Most of the examples and all of the exercises focus on simulating groundwater systems; other examples come from surface-water hydrology and geophysics. The methods and guidelines in the text are broadly applicable and can be used by students, researchers, and engineers to simulate many kinds systems.

"This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is an important source for irrigated agriculture as it generally furnishes reliable and flexible inputs of water. To this extent, groundwater is instrumental in managing risk and optimizing food production. However, this reliance upon shallow aquifer systems for irrigation has turned to dependency. Competition for groundwater is intense both between neighbouring users and among economic sectors. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management."--Preface.

The importance of groundwater to India's economy should not be undervalued. Over the last three decades, the rapid expansion in use of groundwater primarily for irrigation has contributed significantly to agricultural growth, as well as the overall economic development in India. However, the rapid development in groundwater has had its price. In many arid and hard-rock zones, increases in overdraft areas and associated water-quality problems are emerging. 'Groundwater Regulation and Management' provides an assessment of the issues from development to management and discusses the reform agenda.

The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Michael Batty Centre for Advanced Spatial Analysis, University College London Landscapes, like cities, cut across disciplines and professions. This makes it especially difficult to provide an overall sense of how landscapes should be studied and researched. Ecology, aesthetics, economy and sociology combine with physiognomy and deep physical structure to confuse our - derstanding and the way we should react to the problems and potentials of landscapes. Nowhere are these dilemmas and paradoxes so clearly highlighted as in Australia — where landscapes dominate and their relationship to cities is so fragile, yet so important to the sustainability of an entire nation, if not planet. This book presents a unique collection and synthesis of many of these perspectives — perhaps it could only be produced in a land urb- ised in the tiniest of pockets, and yet so daunting with respect to the way non-populated landscapes dwarf its cities. Many travel to Australia to its cities and never see the landscapes — but it is these that give the country its power and imagery. It is the landscapes that so impress on us the need to consider how our intervention, through activities ranging from resource exploitation and settled agriculture to climate change, poses one of the greatest crises facing the modern world. In this sense, Australia and its landscape provide a mirror through which we can glimpse the extent to which our intervention in the world threatens its very existence.

Integrated urban water management relies on data allowing us to analyse, understand and predict the behaviour of the individual water cycle components and their interactions. The concomitant monitoring of the complex of urban water system elements makes it possible to grasp the entirety of relations among the various components of the urban water cycle and so develop a holistic approach to solving urban water problems. Data Requirements for Integrated Urban Water Managements - issuing from UNESCO's International Hydrological Programme project on this topic - is geared towards improving integrated urban water management by providing guidance on the collection, validation, storage, assessment and utilization of the relevant data. The first part of this volume describes general principles for developing a monitoring programme in support of sustainable urban water management. The second part examines in detail the monitoring of individual water cycle components. Two case studies in the final part illustrating attempts to deliver an integrated monitoring system help demonstrate the fundamental principles of sustainable urban water management elaborated here.

This is the digital version of the printed book (Copyright © 2000). Derek Hatley and Imtiaz Pirbhai—authors of Strategies for Real-Time System Specification—join with influential consultant Peter Hruschka to present a much anticipated update to their widely implemented Hatley/Pirbhai methods. Process for System Architecture and Requirements Engineering introduces a new approach that is particularly useful for multidisciplinary system development: It applies equally well to all technologies and thereby provides a common language for developers in widely differing disciplines. The Hatley-Pirbhai-Hruschka approach (H/H/P) has another important feature: the coexistence of the requirements and architecture methods and of the corresponding models they produce. These two models are kept separate, but the approach fully records their ongoing and changing interrelationships. This feature is missing from virtually all other system and software development methods and from CASE tools that only automate the requirements model. System managers, system architects, system engineers, and managers and engineers in all of the diverse engineering technologies will benefit from this comprehensive, pragmatic text. In addition to its models of requirements and architecture and of the development process itself, the book uses in-depth case studies of a hospital monitoring system and of a multidisciplinary groundwater analysis system to illustrate the principles. Compatibility Between the H/H/P Methods and the UML: The Hatley/Pirbhai architecture and requirements methods—described in Strategies for Real-Time System Specification—have been widely used for almost two decades in system and software development. Now known as the Hatley/Hruschka/Pirbhai (H/H/P) methods, they have always been compatible with object-oriented software techniques, such as the UML, by defining architectural elements as classes, objects, messages, inheritance relationships, and so on. In Process for System Architecture and Requirements Engineering, that compatibility is made more specific through the addition of message diagrams, inheritance diagrams, and new notations that go with them. In addition, state charts, while never excluded, are now specifically included as a representation of sequential machines. These additions make definition of the system/software boundary even more straightforward, while retaining the clear separation of requirements and design at the system levels that is a hallmark of the H/H/P methods—not shared by most OO techniques. Once the transition to software is made, the developer is free to continue using the H/H/P methods, or to use the UML or any other software-specific technique.

This collection of papers is a snapshot of modern hydrogeology in which highly technical methods and approaches sit side-by-side with overlapping legal, social, organisational, institutional and governance considerations. Groundwater is integral to many human and environmental systems. Indeed, there appears to be a growing realisation that some of the most pressing physical problems in the field of hydrogeology - over-abstraction, salinization or pollution - can only really be solved by taking a multi-disciplinary approach to the issues that takes all other related professions into account. Whilst a ‘technical’ solution may be readily deciphered, the larger challenge usually lies in the sustainably-funded and widely-accepted implementation of that measure. This book ranges from discussion and debate on the hot topic of hydraulic fracturing of wells or ‘fraccing’ for shale gas and its potential to disrupt groundwater systems, to the application of highly technical modelling procedures to help solve complex, real world problems. It is a window on the preoccupations of modern hydrogeologists and an insight into the way in which hydrogeological techniques and methods are being holistically adapted to address problems in the real world. This book is targeted at professional hydrogeologists, sociologists, experts in governance, law and policy as well as ecologists and other professionals that nowadays all sit alongside groundwater understanding. The book will also appeal to politicians, resource managers, regulators and others interested in sustainable water supply.
