A futuristic approach in water management has been discussed in this descriptive book. It is estimated that there is nearly 1.4 billion km3 of water in this world but only about 3% (39 million km3) of it is available as fresh water. Furthermore, most of this fresh water is found as ice in the arctic regions, atmospheric water or deep groundwater. Since water is a source of life and is vital for all forms of life across the planet, its sustainable use is an extremely crucial issue. Water Management is the fundamental term employed for elucidating all the activities involved in managing the optimum use of the world's water resources. However, only a small percentage of fresh water available can be subjected to water management. It is still a huge amount, but the distinct characteristic of water is that unlike other resources, it is irreplaceable. This book describes an elementary analysis on several topics related to water management from across the globe. The topics elucidated in this book cover politics, recent models for water resource management of rivers and reservoirs as well as issues associated with agriculture. Growing water demands, water quality problems and water pricing have also been considered. Reputed scientists and experts from across the world have contributed descriptive information in this book. It covers a broad range of current issues, describing the current problems and illustrating the complexity of water management.
