Hydraulic engineering is a branch of civil engineering that deals with the flow of fluid, typically water and sewage, through conduits and makes use of gravity for the movement of fluid. It involves designing structures with the capacity to remove or divert water from the roadways and pass the collected water from under the roadway. Hydraulic engineering is also concerned with the technical challenges involved in sewerage design and water infrastructure. It is used for creating bridges, sewers, dams, canals, etc. The computational aspects of hydraulics with respect to civil engineering problems are dealt with under the discipline of computational hydraulics, which contains methods and techniques for numerical simulation of water flows in natural or manmade systems with the aid of computers. In such systems, flow and transport is modeled using computer tools such as computer graphics, statistical analysis methods, electronic databases, and spreadsheets. This book contains some path-breaking studies related to computation, analysis, and modeling within hydraulic engineering. It will serve as a valuable source of reference for graduate and postgraduate students.
