The UK is a country with over 150 years of widespread exploitation of its principal aquifers for public water supply. Increasing demands, greater awareness of environmental pressures and more exacting legislation has heightened the need for quantitative models to predict the impacts of groundwater use. In the UK this has culminated in a unique national, regulator-led programme for England and Wales to develop conceptual and numerical models of the principal bedrock aquifers. The outcomes of this programme will be of interest to the international hydrogeological community, particularly as international legislation such as the European Water Framework Directive requires management of water issues across administrative boundaries with a varied cast of stakeholders. The collection of papers provides a contrast between practitioner- and research-based approaches to assess and predict the anthropogenic impacts and environmental pressures.

This volume presents current issues surrounding groundwater pollution risk assessment and the application of vulnerability and risk assessment maps for the effective protection and management of aquifers. New and improved approaches to intrinsic and specific vulnerability assessment are described, some coupled with geophysical and hydrological surveys and hydrodynamic and transport modelling. Widespread use is made of GIS format.

This accessible new textbook provides a thorough introduction toall aspects of groundwater systems and their management. Usingstraightforward language and analogies to everyday experiences, itexplains the origins, nature, and behavior of subsurface waterwithout resorting to complicated mathematics. Groundwater in the Environment draws on case studies andcutting-edge research from around the world, giving a uniqueinsight into groundwater occurring in a wide range of differentclimate zones and geological settings. This book: provides a robust, practical introduction to groundwaterquality, and a succinct summary of modern remedial technologies forpolluted groundwaters explores how groundwater fits into the wider naturalenvironment, especially in relation to freshwater ecosystems considers the vulnerability of groundwater systems and theeffects of pollution, climate change, land-use change, andoverexploitation examines human dependence on water and the effect that this hason groundwater systems presents vivid examples of geohazards associated with groundwaters explains the whys and wherefores of groundwater modeling examines competing philosophies of groundwater management,making the case for approaches which take social, economic andecological issues into account. Goundwater in the Environment provides an up-to-date,essential introduction for undergraduate students of environmentalsciences, geography and geology. It will also be invaluable toprofessionals working in various fields of natural resourcemanagement who need accessible information on groundwater but whoare reluctant to read conventional texts full of mathematicalnotation. For practicing hydrogeologists and engineers withoutformal training in freshwater ecology, this book provides a `crashcourse' in the new frontiers of groundwater management.

Fractional Operators with Constant and Variable Order with Application to Geo-hydrology provides a physical review of fractional operators, fractional variable order operators, and uncertain derivatives to groundwater flow and environmental remediation. It presents a formal set of mathematical equations for the description of groundwater flow and pollution problems using the concept of non-integer order derivative. Both advantages and disadvantages of models with fractional operators are discussed. Based on the author's analyses, the book proposes new techniques for groundwater remediation, including guidelines on how chemical companies can be positioned in any city to avoid groundwater pollution. - Proposes new aquifer derivatives for leaky, confined and unconfined formations - Presents useful aids for applied scientists and engineers seeking to solve complex problems that cannot be handled using constant fractional order derivatives - Provides a real physical interpretation of operators relevant to groundwater flow problems - Models both fractional and variable order derivatives, presented together with uncertainties analysis

Water Wells and Boreholes focuses on wells that are used for drinking, industry, agriculture or other supply purposes. Other types of wells and boreholes are also covered, including boreholes for monitoring groundwater level and groundwater quality. This fully revised second edition updates and expands the content of the original book whilst maintaining its practical emphasis. The book follows a life-cycle approach to water wells, from identifying a suitable well site through to successful implementation, operation and maintenance of the well, to its eventual decommissioning. Completely revised and updated throughout, Water Wells and Boreholes, Second edition, is the ideal reference for final-year undergraduate students in geology and civil engineering; graduate students in hydrogeology, civil engineering and environmental sciences; research students who use well data in their research; professionals in hydrogeology, water engineering, environmental engineering and geotechnical engineering; and aid workers and others involved in well projects.

Burgeoning population and climate change are among the most critical challenges facing the 21st century. Both have critical implications for groundwater resources, especially in many developing countries where resources are already under pressure. Due to low rainfall and high evaporation in parts of the Middle East and North Africa, groundwater is not being renewed, and groundwater laid down up to 10,000 years ago is literally being mined for irrigation, often very inefficiently. Over recent decades, groundwater levels have fallen dramatically in key grain-growing regions like the American Great Plains and the North China Plain. As the population grows and emerging economies like China and India demand more food, especially water intensive meat products, agricultural demand for water is set to increase. The rapid shift of population from the countryside to the cities is also adding to this pressure; most old wells in Beijing are now dry. Pollution from industry, agriculture and shanty towns is destroying many groundwater resources; some could take 50 years to clean up even with strict and immediate controls. This volume looks at the technical, socio-economic and political problems being faced, and at the developments in groundwater science and management that may help create a sustainable future for our planet.
