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.

Your Guide to Effective Groundwater Management Groundwater Assessment, Modeling, and Management discusses a variety of groundwater problems and outlines the solutions needed to sustain surface and ground water resources on a global scale. Contributors from around the world lend their expertise and provide an international perspective on groundwater management. They address the management of groundwater resources and pollution, waste water treatment methods, and the impact of climate change on groundwater and water availability (specifically in arid and semi-arid regions such as India and Africa). Incorporating management with science and modeling, the book covers all areas of groundwater resource assessment, modeling, and management, and combines hands-on applications with relevant theory. For Water Resource Managers and Decision Makers The book describes techniques for the assessment of groundwater potential, pollution, prevention, and remedial measures, and includes a new approach for groundwater modeling based on connections (network theory). Approximately 30 case studies and six hypothetical studies are introduced reflecting a range of themes that include: groundwater basics and the derivation of groundwater flow equations, exploration and assessment, aquifer parameterization, augmentation of aquifer, water and environment, water and agriculture, the role of models and their application, and water management policies and issues. The book describes remote sensing (RS) applications, geographical information systems (GIS), and electrical resistivity methods to delineate groundwater potential zones. It also takes a look at: Inverse modeling (pilot-points method) Simulation optimization models Radionuclide migration studies through mass transport modeling Modeling for mapping groundwater potential Modeling for vertical 2-D and 3-D groundwater flow Groundwater Assessment, Modeling, and Management explores the management of water resources and the impact of climate change on groundwater. Expert contributors provide practical information on hydrologic engineering and groundwater resources management for students, researchers, scientists, and other practicing professionals in environmental engineering, hydrogeology, irrigation, geophysics, and environmental science.

Groundwater is the world’s largest source of fresh water, but its safe and sustainable exploitation remains a challenge. Egypt's Nile Valley aquifer is the most important renewable aquifer, accounting for approximately 85% of total groundwater use in Egypt. Egypt's long-term development and socioeconomic growth in the Nile Valley depends on this groundwater. Concerns about groundwater assessment, quality, management, and sustainability frame the current status of Nile Valley groundwater supplies. Proper knowledge of the current state of the groundwater quantity and quality in the Nile Valley is vital for the development and management of groundwater resources in Egypt. Due to Egypt's water scarcity, the projected decline in Nile River flow due to climate change, and the development of numerous Nile River basin projects, the situation is critical, and the consequences might be severe. Furthermore, Egypt's growing population puts significant strain on groundwater, which is the second most significant freshwater supply next to the surface water supply coming from the Nile River as Egypt’s share. Several books on the various aspects of Egypt's water resources have been published, but there is insufficient recent information on groundwater in the Nile Valley aquifer, which is essential for Egyptian populations for domestic and irrigation purposes. As a result, this book on the groundwater in the Nile Valley aquifer emerges to complete the picture of Egypt’s water resources as a good example of arid country located in MENA regions with many arid countries. Consequently, the lessons learned from this book could be beneficial to other countries in MENA regions, particularly those in North Africa.

Hydrology covers the fundamentals of hydrology and hydrogeology, taking an environmental slant dictated by the emphasis in recent times for the remediation of contaminated aquifers and surface-water bodies as well as a demand for new designs that impose the least negative impact on the natural environment. Major topics covered include hydrological principles, groundwater flow, groundwater contamination and clean-up, groundwater applications to civil engineering, well hydraulics, and surface water. Additional topics addressed include flood analysis, flood control, and both ground-water and surface-water applications to civil engineering design.

This new book contains the proceedings of the 4th Geoenvironmental Engineering Conference, organised by the British Geotechnical Association and Cardiff University’s School of Engineering, held in Stratford-Upon-Avon in June 2004. The theme of the conference was Integrated Management of Groundwater and Contaminated Land. This book is a compilation of peer-reviewed papers; grouped according to the sessions under which they were presented at the conference. Issues associated with Geoenvironmental Engineering continue to be a major preoccupation for Governments, public and private organisations and the general community around the world. The conference brought together people working in industry, academia and the public sector to discuss the latest ideas and developments in Geoenvironmental Engineering and related fields. The papers in these proceedings reflect the work being undertaken across the discipline. This volume is an indispensable source of information on current research and practice in the field of integrated management of groundwater and contaminated land.
