This volume presents the current state-of-art of the design, construction and operation ofRCC dams in different countries, as well as the innovative methods and techniques indesign and construction, offering an overall view of its concepts, development andinnovation of RCC dams. Subjects covered in this book include new trends, planning anddesign, materials, numerical analysis, construction, operation and performance of RCCdams. as well as development of CSG and other RCC applications in hydraulic structures.The Book will be of particular interest to professionals, dam engineers, managers and alsoorganization responsible for dam management.

From the first experiences of Roller Compacted Concrete (RCC) dams began in 1978,there has been a high speed development of RCC technology applied in dam construction throughout the world for the important advantages of being more economical and more efficient. At the end of 2006 there were over 380 large (H>15m) RCC dams either completed or under construction throughout the World. The first RCC dam over 200m in height (Longtan in China) is about to be completed followed by another two or three of the similar height recently. There is now enough confidence in well-desigened RCC dams of 200m high, which can help to achieve an adequate balance between safety, economy and environmental protection.
