All hydraulic structures are constructed on the solid Earth, which can be mathematically treated as an infinite domain, from the engineering length-scale point of view. This book examines the computational simulation of static and dynamic responses of hydraulic structures, which are constructed on infinite foundations. Moreover, the analysis and design problem of water distribution networks has been and will continue to be a main subject of hydraulic engineering. This book presents a design procedure improved by using power law friction factor, which provides accurate solutions for three types of pipe design problems with considering effect of local losses.
