Описание: The establishment of clean, safe water is one of the major challenges facing societies around the globe. The continued urbanization of human populations, the increasing manipulation of natural resources, and the resulting pollution are driving remarkable burden on water resources. Increasing demands for food, energy, and natural resources are expected to continue to accelerate in the near future in response to the demands of these changing human populations. In addition, the complexity of human activities is leading to a diversity of new chemical contaminants in the environment that represent a major concern for water managers. This will create increased pressure on both water quantity and quality, making it increasingly dif?cult to provide a sustainable supply of water for human welfare and activities.Although protection of water resources is the best long-term solution, we will also need innovative novel approaches and technologies to water treatment to ensure an adequate superior quality resource to meet these needs. Solving tomorrow’s water issues will require unique approaches that incorporate emerging new technologies.Great advances have been made in the area of nanotechnology. Due to their unique physical and chemical properties, nanomaterials are extensively used in antibacterial medical products, membrane filters, electronics, catalysts, and biosensors. Nanoparticles can have distinctly different properties from their bulk counterparts, creating the opportunity for new materials with a diversity of applications. Recent developments related to water treatment include the potential use of carbon nanotubes, nanocompositae, nanospheres, nano?bers, and nanowires for the removal of a diversity of chemical pollutants. By exploiting the assets and structure of these new materials, such as increased surface area, high reactivity, and photocatalytic action, it will be possible to create technologies that can be very ef?cient at removing and degrading environmental pollutants. Understanding and using these unique properties should lead to innovative, cost-effective applications for addressing the complexities of emerging needs for water treatment and protection. Although still in the early stages, research into the application of nanotechnology shows great promise for solving some of these major global water issues. This comprehensive text describes the latest research and application methods in this rapidly advancing field.

Описание: Hydrogeochemistry is of great application in reconstructing the previous groundwater circulation under ice sheets due to meltwater recharging the subsurface having a geochemical signature that could be discriminated from the other sources of water produced under warmer climates. Many hydrogeological factors could affect the geochemical composition of groundwater. These include the climate conditions, the lithology of the substrate and its hydraulic conductivity, the weathering, the length of the flow path, the penetration depth, the groundwater flow velocity and the residence time of groundwater. In recent years, hydrogeochemistry advances in analytical technology have allowed hydrogeochemical surveys to become a very powerful exploration technique. The new research works in this area are very broad and extensive. In this mini book, it is impossible to bring all of these novel techniques. The current Advances in Hydrogeochimistry Research book is limited to some diverse examples in different regions of the earth. As an introduction, chemical interaction between surface water and groundwater has been explained and discussed. A hydrogeochemical perspective of the wetland systems is then drawn. It has been combined with the biological remediation. Contaminant fate and transport in both groundwater and soil are also studied using different image analysis techniques. A case study in an Arab region of the world is comprehensively undertaken and the impact of groundwater pollution and quality on regional economics has been investigated. The concepts, classifications and applications of the groundwater modeling for solute transport simulation have been defined in the saturated porous media of the earth. An African analysis was done on assessing the microbiological quality of potable groundwater from the selected protected and unprotected wells in Zimbabwe. 36Cl for dating groundwater was contributed on the Guarani Aquifer System, located beneath the surface of Argentina, Brazil, Paraguay and Uruguay and is the second largest known aquifer system in the world and is attributed as an important source of freshwater. For semi-arid and arid zones of Iran, geospatial techniques in hydrogeochemistry have been used by intersecting the layers and statistical analysis. Then, a hydrochemical analysis of the bottled mineral waters has been comparatively studied. In another part of Africa, a semiarid part of North Eastern Nigeria, physicochemical characteristics of groundwater are widely determined. It has been also shown that the hydraulic fracking associated with the coalbed methane production has a great impact on water resources. Finally, various case studies have been done on the environmental state of freshwater, natural resources and mine waters in the some parts of Serbia, Spain and Central Asia. In addition, the implications on regional water resources management have been indicated. This book is intended primarily as a textbook at the graduate/research level and as a guide for field engineers, enabling them to remain current with scientific developments. As a simple prerequisite, the readers should have basic background knowledge in groundwater engineering and a general understanding of environmental and geological processes.
Описание: This book reviews the concept, contemporary research efforts and the implementation of Integrated Water Resources Management (IWRM). The IWRM concept was established as an international guiding water management paradigm in the early 1990ies and has become a vital approach to solving the problems associated with the topic of water. The book summarizes fourteen comprehensive IWRM research projects with worldwide coverage and analyses their motivations, settings, approaches and implementation of results. Aiming to be an up-to-date interdisciplinary scientific reference, this book provides a comprehensive theoretical and empirical analysis of contemporary IWRM research, examples of science based implementations and a synthesis of the lessons learnt. It concludes with some major future challenges, the solving of which will further strengthen the IWRM concept.
