This book, which is primarily a textbook for civil engineering undergraduate and graduate students, offers a thorough understanding of open channel flow. The notion of open channel flow, various forces acting on the flow, various channel flow types, velocity distribution and coefficients, and fundamental continuity in 1D and 3D are covered in the beginning of the book. The flow is then steadily altered over time, followed by its differential equation, alluvial channel hydraulics, channel design, and hydraulic leap. The Saint-Venant equations and their solutions using a few numerical techniques in flood routing and dam-break conditions are the text's last section. Summary of Contents Preface. Broad Channel Flow Consistent Flow. Specific Force, Critical Depth Computation, and Specific Energy. channel hydraulics in alluvial systems. Channel design.
