Papers presented at the 10th in a series of conferences on River Basin Management are contained in this book. The included works mark a growing global interest in the planning, design and management of river basin systems and take in to account all aspects of Hydrology, Ecology, Environmental Management, Flood Plains and Wetlands. Catastrophic events such as floods and associated landslides, erosion and sedimentation can have serious effects not only on life and property but also on the basin ecology. Frequently these problems are aggravated by the unforeseen consequences of man made changes in the river basin. This has led in recent years to work on river restoration and rehabilitation with various degrees of success. Changes in the landscape, use of the land and climate conditions leads to a continuous revaluation of river basin management objectives requiring the development of better measuring tools in conjunction with accurate computer technology. Specific themes covered in this volume include: Water resources management; Flood risk management; Ecological and environmental impact; Erosion and sediment transport; Hydrological modelling; River restoration and rehabilitation; Hydropower issues and development; River and watershed management; Water quality issues; Organic contamination management; Agricultural pollution; Transboundary water issues; Estuaries and deltas; Climate change; Remote sensing; Hydraulic structures; Rain water management; Water energy nexus; Drought assessment and management; Ecosystem services.

This book provides a systematic exposition of the design features of constructed wetlands, and their management (in terms of siting, physical maintenance, and operation). Only very few books (or chapters) have been published on constructed wetlands in tropical conditions and none are current. The selection of plant species, managing their growth and harvesting cycles, and the impact these have on the attenuation of organic and inorganic pollutants, nutrients, and pathogens would be of interest to students and practitioners of the art working under tropical conditions. The potential of constructed wetlands as a low-cost intervention for developing countries in tropical regions that faced water pollution problems, in particular, deserves to be explored systematically.

The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution - air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for "zero discharge" can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a "methodology of pollution control. " However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

The capability to generate potable water from polluted sources is growing in importance as pharmaceuticals, microplastics and waste permeate our soil. Nanotechnology allows for improvements in water remediation technologies by taking advantage of the unique properties of materials at this small scale.

This book discusses how climate change and heat islands are a main contributor to water related problems in urban areas in Kosice, Slovakia. Green roofs are used as a tool to assist in solving these water related issues. The need to provide housing in urban areas is expected to rise to 66% in 2050, according to the United Nations. Many urban areas have seen natural permeable green areas replaced with concrete constructions and hard, non-permeable surfaces. The densification of existing built-up areas is responsible for the decreasing vegetation, which results in the lack of evapotranspiration cooling the air, thereby creating urban heat islands. Several studies, discussed in this book, have shown that natural and permeable surfaces, as in the case of green roofs, can play a crucial role in mitigating this negative climate phenomenon and providing higher efficiency for buildings, leading to savings such as water, one of the focal points of this research.

This book presents the state-of-the-art in the area of water remediation. It covers topics such as decentralized ecological wastewater treatment, applications of remote sensing and geographic information systems (GIS) in water quality monitoring and remediation, water remediation through nanotechnology, and processes used in water purification. The contents of this volume will prove useful to researchers, students, and policy makers alike.

Water is essential for life, a strategic resource for every country and population. Its availability and sanitary safety is highly connected with the health and economy status of population. Burden of disease due to polluted water is a major public health problem throughout the world. Many pollutants in water streams have been identified as toxic and harmful to the environment and human health, and among them arsenic, mercury and cadmium are considered as high priority ones. Providing population with safe drinking water became the priority and at the same time a big challenge for the modern society. Many funding agencies in various countries have assigned a high priority to the envir- mental security and pollution prevention. UN, being one of them, launched the "International Decade for Action: Water for life 2005-2015. " Therefore, today's political and social climate presents an important opportunity to implement principles of sustainable development and to preserve resources essential for future life. This process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity. The NATO Advanced Research Workshop "Water Treatment Te- nologies for the Removal of High-Toxicity Pollutants" took place on September 13-17, 2008 in Ko ice, Slovak Republic."

Forming the 10th volume from this successful international conference series, this book features research from scientists, practitioners and other experts working across the field of water resources management. Water is essential for sustaining life on our planet and its uneven distribution is a source of permanent conflict. The growth of human population combined with the irregularity in precipitation and water availability may restrict even further the access to water in certain regions of the world. This problem is made more severe by anthropogenic activities that affect its quality. Moreover, changes in the landscape, use of the land and climate conditions lead to a continuous revaluation of river basin management objectives. This requires the development of better measuring tools as well as the use of increasingly accurate computer software. This volume provides an insight into the state of the art in the current technology, techniques and solutions in sustainable water resources management as they have been developed and applied in different countries. Themes related to water resources include: Water management and planning; Water rights and accessibility; Water markets economics and policies; Climate change; Irrigation; Water resources in arid regions; Ground water; Hydraulic engineering; Trans-boundary water management; Water, food and energy; Water and the community; Integrated water analysis; Wetlands as water sources.

The concept for the Water Environment of Cities arose from a workshop "Green 1 Cities, Blue Waters" workshop held in 2006. The workshop assembled experts from engineering, planning, economics, law, hydrology, aquatic ecology, geom- phology, and other disciplines to present research ?ndings and identify key new ideas on the urban water environment. At a lunch discussion near the end of the workshop, several of us came to the recognition that despite having considerable expertise in a narrow discipline, none of us had a vision of the "urban water en- ronment" as a whole. We were, as in the parable, blind men at opposite ends of the elephant, knowinga great deal about the parts, but notunderstandingthe whole. We quickly recognized the need to develop a book that would integrate this knowledge to create this vision. The goal was to develop a book that could be used to teach a complete, multidisciplinary course, "The Urban Water Environment," but could also be used as a supplemental text for courses on urban ecosystems, urban design, landscapearchitecture, water policy, waterqualitymanagement andwatershed m- agement. The book is also valuable as a reference source for water professionals stepping outside their arena of disciplinary expertise. The Water Environment of Cities is the ?rst book to use a holistic, interdis- plinary approach to examine the urban water environment. We have attempted to portrayaholisticvisionbuiltaround theconcept of water as a coreelement ofcities. Water has multipleroles: municipalwatersupply, aquatichabitat, landscapeaesth- ics, and recreation. Increasingly, urban water is reused, serving multiple purposes.
