A multidisciplinary text, considering both general issues and principles of water law and administration at national and international level, dealing with current legal and institutional aspects of water resources management. New information has been added in this latest edition, including the situation in countries previously a part of the former Soviet Union. Added emphasis is given to areas of growing topical importance, such as stakeholders' influence on decisions, the need to maintain a minimum flow in water bodies and the necessity for legislation in support of water resource monitoring. There is new material on the European Union Water Framework Directive which is referenced heavily in the work. The book is aimed at those who carry out functions in water resources administration and those who deal with legal issues raised by water management. The book will be particularly useful to academics and graduate students of law, engineering, hydrology, hydrogeology, sanitary engineering and planners, as well as national and international water resources managers.
