The Third Edition Of This Book Recognises Two Important Developments That Have Taken Place In Recent Years.(1) Mathematical Modelling Of Alluvial River Processes, And(2) Environmental Aspects Relating To Sedimentation.Both Of These Factors Have Been Duly Considered In This Edition. With Its Detailed Analysis And Clear Presentation, This Book Would Be Extremely Useful For Practising Civil Engineers. It Would Also Serve As An Authoritative Reference Source For Graduate And Senior Undergraduate Civil Engineering Students.
Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.
Since the publication of its first edition in 1999, 'The Hydraulics of Open Channel Flow' has been praised by professionals, academics, students and researchers alike as the most practical modern textbook on open channel flow available. This new edition includes substantial new material on hydraulic modelling, in particular addressing unsteady open channel flows. There are also many new exercises and projects, including a major new revision assignment. This innovative textbook contains numerous examples and practical applications, and is fully illustrated with photographs. Dr Chanson introduces the basic principles of open channel flow and takes readers through the key topics of sediment transport, hydraulic modelling and the design of hydraulic structures. - Comprehensive coverage of the basic principles of key application areas of the hydraulics of open channel flow - New exercises and examples added to aid understanding - Ideal for use by students and lecturers in civil and environmental engineering
OPEN CHANNEL DESIGN A fundamental knowledge of flow in open channels is essential for the planning and design of systems to manage water resources. Open channel design has applications within many fields, including civil engineering, agriculture, hydrology, geomorphology, sedimentology, environmental fluid and sediment dynamics and river engineering. Open Channel Design: Fundamentals and Applications covers permissible velocity, tractive force, and regime theory design methodologies and applications. Hydraulic structures for flow control and measurement are covered. Flow profiles and their design implications are covered. Sediment transport mechanics and moveable boundaries in channels are introduced. Finally, a brief treatment of the St. Venant equations and Navier-Stokes equations are introduced as topics to be explored in more advanced courses. The central goal is to prepare students for work in engineering offices where they will be involved with aspects of land development and related consulting work. Students will also be prepared for advanced courses that will involve computational fluid dynamics approaches for solving 2-d and 3-d problems in advanced graduate level courses. Offering a fresh approach, Open Channel Design: Fundamentals and Applications prepares students for work in engineering offices where they will be involved with aspects of land development and related consulting work. It also introduces the reader to software packages including Mathematica, HecRas and HY8, all widely used in professional settings.
