PREFACE
The Brahmaputra River is a precious gift of Nature to India and especially to its northeast region. The meaning of this gift becomes evident immediately when one considers the vastness of water resources which the Brahmaputra River basin possesses. Nearly 30% of India's water resources potential and 41% of the country's total hydropower potential are found in this basin. In terms of the average discharge, the Brahmaputra River is the fifth largest river in the world. Traversing a distance of about 2,900 kilometers from Tibet at an elevation of 5,150 meters to the Bay of Bengal and draining an area of nearly 1.6 million square kilometres shared by Tibet, India and Bangladesh, it has shaped the social, economic, cultural, religious, political, and linguistic fabric of the northeast region of India from time immemorial. Its majestic disposition is nothing short of poetic. The northeast region has a colourful ethnic and non-ethnic population and represents almost a miniature India. Its biodiversity of flora and fauna and other natural ecosystems is unsurpassable.
The northeast region of India is endowed with enormous natural resources and the huge potential of the Brahmaputra River basin. These resources notwithstanding, this part of India remains woefully underdeveloped. The current state of low development of the northeast region can arguably be attributed to a multitude of factors. Regardless of the debate about these factors, what is abundantly clear is that a sustainable development of this region cannot be achieved without the water resources development of the Brahmaputra River basin. To that end an integrated basinwide approach is needed. This approach must combine social, political, economic, administrative, cultural, and legal considerations with scientific and technological paradigms. It must involve people's participation and must strive to promote the larger interest of the region rather than the good of a few. It is these considerations which motivated the undertaking of this book project. The theme of this book is vast and no single individual has the expertise, the indepth knowledge, or the experience of all aspects of water resources of the Brahmaputra basin. Therefore the editors solicited contributions from the people representing different disciplines bearing on the development of water resources and who are well known in their speciality areas. It is hoped that this book will stimulate further interest and development in the Brahmaputra River basin.
The subject matter of this book is divided into four sections encompassing 30 chapters. The first section, comprising seven chapters, presents preliminaries needed for planning and developing a water resources project. These relate to the atmosphere, lithology, and pedology. Introducing the theme of the book in chapter 1, the weather and climate of the Brahmaputra valley are discussed in chapter 2, followed by a short treatment of hydrometeorology in chapter 3. Soils and agriculture of the Brahmaputra basin are presented in chapter 4. The next three chapters deal with various aspects of geology of this basin. Specifically, chapter 5 presents an overview of the Brahmaputra River, chapter 6 fluvial geomorphology, and chapter 7 hydrogeology of the Brahmaputra basin.
Section 2 deals with hydrology and hydraulics that constitute the engineering
xi
foundation of any water resources project. This section comprises 6 chapters. The hydrology of the Brahmaputra basin is treated in chapter 8. The next five chapters discuss hydraulic issues. Chapter 9 provides a discussion of channel processes, followed by a discussion of spatio-temporal morphological features in chapter 10. Mathematical modelling and braid indicators are treated in chapter 11 and hydraulic structures of the Brahmaputra basin in chapter 12. The section is concluded with a discussion of scour around spurs with particular reference to the Gumi site in the basin in chapter 13.
For the planning of water resources a number of constraints must be taken into account. Section 3, encompassing 9 chapters, is devoted to a discussion of some of these constraints. Chapter 14 reflects on preliminary considerations required in water resources planning. Chapter 15 dwells on the problems arising owing to flooding in the Brahmaputra basin and the prospects for addressing them from an administrative perspective. The role of the Brahmaputra in Assam's economy is examined in chapter 16, followed by a close look at the financial constraint to development of Assam in chapter 17. The social and cultural fabric of the Brahmaputra basin is analysed in chapter 18. The remaining three chapters deal with ecological and environmental issues. The ecology of the Brahmaputra basin is discussed in chapter 19, followed by a discussion on wetlands and their role in geo-environment in chapter 20. Water quality, sediment biogeochemistry, and mineral transport are presented in chapter 21. The section is concluded with a discussion of cropping systems in the Brahmaputra basin in chapter 22.
The concluding section 4 is comprised of 8 chapters and deals with water resources development. Chapter 23 discusses groundwater development, followed by a discussion of irrigation development in chapter 24. A discussion of power development is presented in chapter 25. Water resources development may playa key role in the transport of goods. Chapter 26 discusses navigation and chapter 27 presents transport infrastructural scenarios. Flooding is an annual problem in the Brahmaputra basin. Flood management is the theme of chapter 28. For effective flood management modem tools for data acquisition, such as remote sensing, and processing of such data through geographical information systems (GIS) are needed and these are discussed in chapter 29. This section is concluded with a discussion of seismotectonic and earthquake design parameters in chapter 30, for the Brahmaputra basin is one of the most seismically active areas of the world and this information is vital for design of hydraulic structures.
The book will be useful to engineers, agricultural scientists, environmentalists, economists, planners, managers, politicians, and administrators who are concerned with development of water resources in the Brahmaputra basin. The people of the northeast are the best symbol of the current state of development of their region in general and what this mighty river has done and can do for them. The book is, therefore, dedicated to them. The editors would like to take this opportunity to express their deep gratitude to the contributors who took time from their busy schedules to write their contributions. The book symbolizes their hard work. Dr. S. Jain, National Institute of Hydrology, provided invaluable assistance with the final preparation of the book manuscript. His

assistance is most gratefully acknowledged. Our families were supportive of this book project from the beginning and without their support the book would not have come to fruition.
