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.

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."

Natural and constructed wetlands play a very important role within the landscape and their ecological services are highly valuable. Water management, including flood water retention, biomass production, carbon sequestration, wastewater treatment and as a biodiversity source are among the most important ecological services of wetlands. In order to provide these services, wetlands need to be properly evaluated, protected and maintained. This book provides results of the latest research in wetland science around the world. Chapters deal with such topics as the use of constructed wetlands for treatment of various types of wastewater, use of constructed wetlands in agroforestry, wetland hydrology and evapotranspiration, the effect of wetlands on landscape temperature, and chemical properties of wetland soils.

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.

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.
