Interlinking of the rivers of the country as ordered by the Supreme Court recently poses a serious challenge to the policy makers and the Government. While financial, technical and the people?s problems related to this venture are extremely difficult, the issue of sustainability after its execution becomes an important agenda. The book, on an optimistic note, assumes that all hurdles would be crossed and a system will be put on ground. Though, sustainability depends on many aspects of such a gigantic exercise, the book here deals with the issues of dam safety and operation and maintenance. The above two topics have been brought into focus in this book, as they are critical to the long-term survival of this project. The book will be useful for every one concerned with water, its demand, supply, distribution and consumption.
