About this eBook

Preface to the Second Edition I am glad to bring out this revised and enlarged edition of Water Power Engineering text and reference book. Since the publication of the first edition more than three decades ago, the hydro-power sector has seen several developments. Small-scale hydro-power attracted attention and started its contribution to meet the challenge of power deficit. With the activists becoming even more vociferous the environmental issues got prominence in various discussions globally that enabled the planners and decision makers to formulate guidelines for scrutiny of hydro-power projects for environmental and forest clearance, including rehabilitation and resettlement of project-affected people. The revised edition of the book therefore has two additional chapters one on small-scale hydro projects and the other on environmental impact of water resources projects. Although the need for revision of the book had been felt long time back, due to various circumstances it could not be done. Unfortunately, Prof. MM Dandekar, the main spirit behind the book, who was guiding the revision work passed away in 2002. However, his memory which is always inspirational, as also the constant enquiries from readers all over the world, proved to be the driving force in completion of this revised, updated and enlarged edition. All the chapters have now been thoroughly revised and updated with latest information on the subject. Several relatively new developments, technologies and structures, for example stepped and piano key type spillways fuse gates and fuse plugs for spillways concrete faced rock-fill dams CFRD , rock-filled concrete RFC dams and roller compacted concrete RCC dams reverse flow throttling in surge tanks for pumped-storage plants wave power generation devices like Archimedes wave swing, the pelamis, the wave dragon etc., have been added in the relevant chapters. Issues such as sedimentation in the dam-related storages affecting power generation, multiplier effect of dams, greenhouse gases from reservoirs, climate change and hydro-power, abrasion in hydraulic machines, etc., have also been discussed so as to cover the latest concerns in the field of hydel power. It was suggested by some well-wishers that chapters on irrigation engineering be also added to the book. It is humbly submitted that it was considered prudent for the time being to maintain the exclusivity of the subject of water power engineering as was contemplated when the book was first written. While seeking apology from the readers for the inordinate delay in the revision of the book, it is hoped that the updated information will be useful for the students as well as those interested in the subject. Suggestions for further improvement of the book will be highly welcomed from the discerning readers. K N Sharma
Preface to the First Edition This book is planned essentially as a textbook for the students interested in Water Power Engineering. This subject is a vast area of engineering, employing diverse disciplines and needs large handbooktype volumes in order to deal with all the aspects thoroughly. As a matter of fact, many such handbooks are already available. On the other hand, there is hardly any book that is suitable for the instructional use in the engineering faculty. While this has been our major motivation in writing this book, we have taken ample care to see that the field engineers active in this area would find the information content in this treatise of substantial use. The basic design principles have been carefully enunciated and the detailed design practices have been indicated. Subjects like hydrology, dam design, turbines and other mechanical and electrical equipments are vast subjects by themselves and to include the comprehensive design procedures is not even possible in a book of this kind.
