Available in PDF, EPUB and Kindle. Book excerpt: Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.

Download or read book How the World Will Change with Global Warming written by Trausti Valsson and published by How the World will Change. This book was released on 2006 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hotter summers and milder winters have already made most of us aware of what scientists say is a trend towards extensive global warming. Most of the experts accompany their predictions with dire warnings of the resulting rising sea levels and spreading deserts. Trausti Valsson's approach to the problem of global warming is a refreshing look at the advantages that will ensue. With the melting of the sea ice in the north, shipping routes will regularly include the passage north of Siberia and, slightly later, a north-west passage through the Canadian Archipelago. This means that countries bordering the Pacific and Atlantic Oceans will become "closer" to each other and that ships too wide for the Panama and Suez Canals can easily transport oil and other cargoes via the shorter routes over the Arctic Ocean. The warming climate and melting ice will make oil and mineral resources in northern areas easily accessible for exploitation and will make the far north comfortable for human habitation, replacing the living spaces around the central areas of the globe that will become too hot for habitation. Valsson recognizes the fact that the world's climate has changed many times in the past and that the present warming trend is not new. However, he underlines the importance of the international agreements for reducing greenhouse gas emissions, which are largely to blame for the current warming trend. He also promotes the view that even in the face of the very many negative consequences, we need to maintain a positive attitude towards the changes that are coming upon us, a refreshing view which he presents through text and a wealth of informative maps.
Download or read book Coastal Wetlands written by Gerardo M.E. Perillo and published by Elsevier. This book was released on 2009-01-18 with total page 975 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.

Download or read book Modeling Groundwater Flow and Contaminant Transport written by Jacob Bear and published by Springer Science & Business Media. This book was released on 2010-01-18 with total page 851 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
