Civil Engineering Hydraulics and Engineering Hydrology

The objective of this book is to give knowledge of open channel hydraulics and hydrology, leading to understanding of the scientific foundations and basic principles of these fields, and the ability to apply hydraulic and hydrological methods to engineering applications in an integrated way. The first part of the book describes an assessment of the literature and recent developments on the shallow wake in an open channel flow and secondary currents and turbulence over a non-uniformly roughened open-channel bed. Then we present flow patterns in an open channel confluence with increasingly dominant tributary inflow and a novel approach for estimating the recurrence intervals of channel-forming discharges. After that, we try to find the effect of the hydraulic retention time on the performance of an ecological wastewater treatment system with a constructed wetland and rehabilitation priority determination of water pipes based on hydraulic importance.
