The 26 papers in this volume cover: catchment treatment and reservoir sediment ation; de-silting and silt disposal; modelling techniques; hydraulic design considerations; and mechanical design and material technology.

An examination of how silt has a major impact on the operation of hydropower projects in terms of the silting of reservoirs, with particular reference to India where one-third of the Earth's silt material originates. An effort is made to raise awareness of silt issues in the minds of hydropower engineers, considering silting problems in hydropower projects on the Indian sub-continent. Also under discussion are environmental and economic aspects of silt management; reduction of silt by implementing ISO 1400 for hilly projects; technical treatments of reservoir sedimentation, desilting and its economic optimization, damage mechanisms and their analysis, and design criteria. Although this book considers the problem of silting from several viewpoints, it focuses on the design of hydropower plants in India.

Underground facilities, such as tunnels, sewer, water and gas networks form the backbone of the economic life of the modern city. In densely populated areas where the demands for transportation and services are rapidly increasing and the construction of new roads and railways are prohibited, the construction of a tunnel might be the only alternative. Brief and readable, this reference is based on a combined 75 years of field experience and places emphasis is on simple practical rules for designing and planning, underground infrastructures. The books' begins with a clear and rigorous exposition of the classification of underground space, important considerations such as geological and engineering and underground planning. This is followed by self-contained chapters concerning applications for underground water storage, underground car parks, underground metros & road tunnels and underground storage of crude oil, lpg and natural gas. The book has 15 chapters covering various usage of underground space. There are about 135 figures and tables. The book contains about 20 case histories/examples. One of the first book to address all of the major areas in which this technology is used, this book deals with major topics such as: hydroelectric projects with modern planning of complex underground structures; underground storages of food items, crude oil and explosives and highly cautious underground nuclear waste repositories. Rail and road tunnels and TBM are described briefly. Risk management in underground infrastructures is of vital importance. Civil Engineers, Mining Engineers, and Geotechnical Engineers will find this book a valuable guide to designing and planning underground infrastructures both in terms of its applications. - Risk management method for underground infrastructures - Vital tips for the underground storage of food, water, crude oil, natural gas and munitions - Provides design tips for Underground Parking Facilities - Instruction for the designing planning and construction for underground Metros and road tunnels - Planning and design of underground nuclear waste repositories - Clearly explains the benefits and drawbacks of underground facilities - Quick guide to the various modern mechanical underground parking options - Explanation of construction planning and Risk management - Places expert advice for planning and constructing projects at the finger tips

First authored book to address materials' role in the quest for the next generation of energy materials Energy balance, efficiency, sustainability, and so on, are some of many facets of energy challenges covered in current research. However, there has not been a monograph that directly covers a spectrum of materials issues in the context of energy conversion, harvesting and storage. Addressing one of the most pressing problems of our time, Materials in Energy Conversion, Harvesting, and Storage illuminates the roles and performance requirements of materials in energy and demonstrates why energy materials are as critical and far-reaching as energy itself. Each chapter starts out by explaining the role of a specific energy process in today’s energy landscape, followed by explanation of the fundamental energy conversion, harvesting, and storage processes. Well-researched and coherently written, Materials in Energy Conversion, Harvesting, and Storage covers: The availability, accessibility, and affordability of different energy sources Energy production processes involving material uses and performance requirements in fossil, nuclear, solar, bio, wind, hydrothermal, geothermal, and ocean energy systems Issues of materials science in energy conversion systems Issues of energy harvesting and storage (including hydrogen storage) and materials needs Throughout the book, illustrations and images clarify and simplify core concepts, techniques, and processes. References at the end of each chapter serve as a gateway to the primary literature in the field. All chapters are self-contained units, enabling instructors to easily adapt this book for coursework. This book is suitable for students and professors in science and engineering who look to obtain comprehensive understanding of different energy processes and materials issues. In setting forth the latest advances and new frontiers of research, experienced materials researchers and engineers can utilize it as a comprehensive energy material reference book.
