It emphasizes channel designs and channel performance evaluations. Open channel hydraulics in a closed conduit are also illustrated by the designs of a culvert under a partially full or full flow condition.
Emphasis is on designs of urban flood channels using the concept of multiple design events.
For a channel having a simple cross section, the duality theory was introduced to the optimization of hydraulic efficiency by either the least excavated channel area, or the maximum delivery capacity. For a channel with a composite cross section, the design procedures and equations were developed to size the low flow section and overflow bank areas on the floodplain. Designs of a trickle channel running through a constructed wetland or park area are also covered. This book provides a theoretical review and numerical examples for illustrating a supercritical flow in curve channels. A two-step design procedure was developed in coping with surface waves including superelevation, cross waves, oblique jumps and roll waves.
