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.

The Hydrology of the UK assesses the changing hydrology of the UK, focusing on key issues that affect the fundamental hydrological processes and have important implications for water resource management, flood risk and environmental quality. The bookis divided into 3 sections: Section 1 examines the causes of change to the hydrology of the UK, including the impact of climate change, land use and geomorphological change, and dam construction. Section 2 assesses the effects of these pressures on UK rivers, goundwater, lakes, ponds, reservoirs and wetlands, looking at water quality, degradation, pollution and protection. Section 3 examines the responses of goverment organisations responsible for planning and management of water, including Environment Agencies, British Hydrological Society and the growing urgency for a World Hydrology Initiative. Change will continue to be a major feature of UK hydrology in the future. This book provides an understanding of the changing hydrology of the UK and the international scene today and looks to the needs for the future.

Initially, the role of snow and ice in the global water balance is assessed and methods of snow measurements are explained. Remote sensing is dealt with with regard to periodical snow cover mapping. Last advances and refinements refer to spatial resolution, cloud interference and separate monitoring of snow and glacier ice. Following a review of snow melt and runoff modelling, the Snowmelt Runoff Model (SRM) demonstrates the merits of remote sensing in snow hydrology by using the satellite data as a direct input variable. Applications in over 100 mountain basins around the world are documented, with surface areas ranging from 0.3 km2 to 900.000 km2. Based on runoff modelling, runoff forecasts are dealt with including seasonal and short term forecasts as well as computation of hydrographs from forecasted temperatures and precipitation. The climate change is becoming a major concern of our times. The effect of various climate scenarios on the seasonal snow cover and runoff is evaluated by the updated computer program which also enable the real-time runoff forecasts to be improved. As a final note, a method is outlined to predict the decline of glaciers in the warming climate.

Hydrology is vital to human civilisations as well as to natural ecosystems, yet it has only emerged as a distinct scientific discipline during the last 50 years or so. This book reviews the development of modern hydrology primarily through the experiences of the multidisciplinary team of scientists and engineers at Wallingford, near Oxford, who have been at the forefront of many of the developments in UK hydrological research. These topics include: • The development of basic understanding through the collection of data with specialised instrumentation in experimental basins • The study of extreme flows – both floods and droughts • The role moisture in the soil • Studies of the processes controlling evaporation • Water resource studies • Modelling and prediction of the extremes of flow improved • Understanding of water quality issues • A widening recognition of the importance of an ecosystem approach • Meeting the challenges of climate change, • Data handling • Future developments in hydrology and the pressures which generate them. Readership: hydrologists in both academia and a wide range of applied fields such as civil engineering, meteorology, geography and physics, as well as advanced students in earth science, environmental science and physical geography programmes worldwide.

In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers. The basic approach of this book is to accurately describe the underlying physics of groundwater flow and solute transport in heterogeneous porous media, starting at the microscopic level, and to rigorously derive their mathematical representation at the macroscopic levels. The well-posed, macroscopic mathematical models are formulated for saturated, single phase flow, as well as for unsaturated and multiphase flow, and for the transport of single and multiple chemical species. Numerical models are presented and computer codes are reviewed, as tools for solving the models. The problem of seawater intrusion into coastal aquifers is examined and modeled. The issues of uncertainty in model input data and output are addressed. The book concludes with a chapter on the management of groundwater resources. Although one of the main objectives of this book is to construct mathematical models, the amount of mathematics required is kept minimal.

To increase access to sustainable supplies of safe water for the poor, groundwater resources need to be exploited successfully, sustainably and economically on a much larger scale than they are at present. Unfortunately, techniques for finding and exploiting groundwater are not widely available. This book sets out to be a user-friendly guide to developing groundwater for rural water supplies. It is specifically designed and developed to meet the needs of rural water supply project staff in developing countries. It provides information on simple, effective techniques for siting wells and boreholes, assessing resource sustainability, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors endeavour to set the technical aspects of rural water supply firmly in the relevant socio-economic context, so that guidance given is not in conflict with community aspects.

The Chernobyl Nuclear Power Plant (NPP) disaster that occurred in Ukraine on April 26, 1986, was one of the most devastating in human history. Using this as a case study, the AGU monograph Groundwater Vulnerability: Chernobyl Nuclear Disaster is devoted to the problem of groundwater vulnerability, where the results of long-term field and modeling investigations of radionuclide transport in soil and groundwater, within the Ukrainian part of the Dnieper River basin (Kyiv region of Ukraine), are discussed. The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater. This volume also includes the evaluation of the effect of preferential and episodic flow on transport of radionuclides toward the aquifers and risk assessment of groundwater vulnerability, which can further assist future researchers in developing remediation technologies for improving drinking water quality. Further, this volume sheds light on the consequences of groundwater contamination from nuclear disasters and assists with assessing the risks associated with contamination and developing effective remediation technologies. Volume highlights include discussions of the following: - Assessment of groundwater vulnerability to contamination from the Chernobyl nuclear disaster - Novel analytical results of the 25-year investigations of groundwater contamination caused by Chernobyl-born radionuclides - The wealth of data on different modes of radioactive transport in the atmosphere, water, and soils, and along the food chains - The hydrogeological and physico-chemical processes and factors in groundwater contaminated zones - The applicability of commonly used methods of the evaluation of groundwater vulnerability - A unique method of fluid dynamics that involves an anomalously fast migration of contaminants through zones of preferential flow from the land surface toward groundwater - Building confidence in the assessment of migration pathways of radionuclides in the biosphere - Assessment and prediction of the consequences of the nuclear accident, which can shed light on protection from global nuclear accidents - Analogue information for different nuclear waste disposal and environmental projects around the world
