It has been more than 140 years since water was used to generate electricity. Especially since the 1970s, with the advancement of science and technology, new technologies, new processes, and new materials have been widely used in hydropower construction. Engineering equipment and technology, as well as cascade development, have become increasingly mature, making possible the construction of many high dams and large reservoirs in the world. However, with the passage of time, hydropower infrastructure such as reservoirs, dams, and power stations built in large numbers in the past are aging. This, coupled with singular use of hydropower, limits the development of hydropower in the future. This book reports the achievements in hydropower construction and the efforts of sustainable hydropower development made by various countries around the globe. These existing innovative studies and applications stimulate new ideas for the renewal of hydropower infrastructure and the further improvement of hydropower development and utilization efficiency.

The 750 pages of the book (in 3 volumes) cover essentially all conceivable aspects of pumps - hydraulics, bearings, lubrication, mechanical seals and packings, cavitation, materials of construction, alignment, vibrations, energy, and efficiency improvement methods, reliability concerns, and solutions, repairs and upgrades, culminating with a "MacGyver Specials" section reflecting on the real-life balance between the theoretical approach to solutions and a practical "just-fix-it-now" attitude.The book will be a great asset to both young engineers starting their career in the industry, as well as to the old-timers who will find many practical cases described in the book familiar and reflective of their own experiences. Maintenance and operating personnel of the water and wastewater plants, power stations, paper mills, chemical plants, and other industries, will find advice and suggestions on how to handle various problems they encounter with pumps in their daily work. The book should be a valuable addition to anyone's collection, to add some sense, humor, to relate their own life experiences, and to take difficulties and problems with a sense of patience, wisdom, keeping in mind that "vanity... all is vanity". Enjoy!

As well as describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments.

Discusses the functions of revetments and the different aspects of structural performance. This book aims to enable the engineer to choose the most stable, appropriate and cost-effective revetment system, for a given situation. It guides through the design process, and helps in the identification of hydraulic loading conditions.

This book presents new concepts to design urban channels with considerations of multiple land uses and multiple design events such as: Blending urban channels into urban greenbelts and parks for the purposes of recreations and sports. On top of theories and concepts, numerous practical design examples are presented using a systematic approach to integrate multiple purposes to design the waterway and its floodplains.This book also applies the green concept to urban channel designs. All channels to be designed with considerations of wetlands, greenbelts, water-front parks, and recreational open space with bike paths and sport fields. All hydraulic structures across the floodplain need to achieve the hydraulic goals, and also to accommodate recreational purposes such as rafting, kayaking, and wild life habitats. As always, urban channel shall be designed to be the assets to better the urban life, and as the major infrastructure to improves the quality of water environment.This book is an excellent textbook and resource for senior designers in Civil Engineering, Water Resources, Hydraulic and Hydrologic Engineering, and a useful technical reference for water-related projects in Public Works and Urban Infrastructure. Examples are presented with calculation details and procedures using EXCEL Spread Sheet Approach.From the TABLE OF CONTENTSCHAPTER 1 - OPEN-CHANNEL HYDRAULICSFrom the TABLE OF CONTENTSCHAPTER 1 - OPEN-CHANNEL HYDRAULICS- CLASSIFICATION OF CHANNELS- CLASSIFICATION OF CHANNEL FLOWS- SLOPES IN CHANNEL FLOW- CROSS SECTIONAL ELEMENTS- EMPIRICAL FORMULA- ROUGHNESS COEFFICENT- NORMAL FLOWCHAPTER 2 - HYDRAULIC DROP AND JUMP- SPECIFIC ENERGY- SPECIFIC FORCECHAPTER 3 - ENERGY DISSIPATION BASIN- WEIR HYDRAULICS- STILLING POOL- PLUNGING POOLCHAPTER 4 - DROP STRUCTURE FOR GRADE CONTROL- CONCEPT OF PERMISSIBLE VELOCITY- CONCEPT OF PERMISSIBLE FROUDE NUMBER- DESIGN CONSIDERATION- PLUNGING POOL- WATER SURFACE PROFILECHAPTER 5 - CONCRETE CHANNEL- DESIGN CONCERNS IN CONCRETE CHANNEL- HEIGHT OF FREEBOARD- SUPERELEVATION- EFFICIENT CHANNEL SECTIONSCHAPTER 6 - GRASS CHANNEL- GRASS LININGS- MANNING'S ROUGHNESS FOR GRASS LININGS- GRASS CHANNEL DESIGNCHAPTER 7 - RIPRAP CHANNEL- RIPRAP LINING- DESIGN CONSIDERATIONS- STREAM POWER-BASED METHOD- SHEAR STRESS-BASED METHODCHAPTER 8 - FLOOD CHANNEL DESIGN- LOW FLOW CHANNEL- TRICKLE CHANNEL- WETLAND CHANNEL- DESIGN CRITERIA FOR COMPOSITE CHANNEL- CONVEYANCE CAPACITY IN COMPOSITE CHANNELCHAPTER 9 - HIGH GRADIENT CHANNEL- STABILITY OF SUPERCRITICAL FLOW- ROLL WAVESCHAPTER 10 - CULVERT HYDRAULICS- CULVERT DESIGN CONSIDERATIONS- CULVERT SIZING- CULVERT HYDRAULICREFERENCES

Som indledning handler bogen om de fysiske principper for at give en bedre forståelse af sammenhængene i den grundlæggende hydraulik.I de efterfølgende afsnit er de enkelte hydraulikkomponenters opgaver og funktioner udførligt beskrevet – herunder pumper, motorer, cylindre, trykventiler, retningsventiler, patronventiler, strømventiler, proportionalventiler og akkumulatorer.
