  Computational River Dynamics
Posted by: ska51 - 08-26-2011, 06:28 AM - Forum: Water & Hydraulic Engineering - Replies (1)


Computational River Dynamics

Author: Weiming Wu | Size: 4.70 MB | Format: PDF | Publisher: CRC Press; 1 edition | Year: 2007 | pages: 508 | ISBN: 0415449618 & 9780415449618

Product Description:

Comprehensive text on the fundamentals of modeling flow and sediment transport in rivers treating both physical principles and numerical methods for various degrees of complexity. Includes 1-D, 2-D (both depth- and width-averaged) and 3-D models, as well as the integration and coupling of these models. Contains a broad selection of numerical methods for open-channel flows, such as the SIMPLE© algorithms on staggered and non-staggered grids, the projection method, and the stream function and vorticity method. The state-of-the-art in sediment transport modeling approaches is described, such as non-equilibrium transport models, non-uniform total-load transport models, and semi-coupled and coupled procedures for flow and sediment calculations. Sediment transport theory is discussed and many newly-developed, non-uniform sediment transport formulae are presented. The many worked examples illustrate various conditions, such as reservoir sedimentation; channel erosion due to dam construction; channel widening and meandering; local scour around in-stream hydraulic structures; vegetation effects on channel morphodynamic processes; cohesive sediment transport; dam-break fluvial processes and contaminant transport. Recommended as a reference guide for river and hydraulic engineers and as a course text for teaching sediment transport modeling, computational free-surface flow, and computational river dynamics to senior students.


Review of this book from Amazon:

‘This book is a brand new addition to the sparse literature on computational river dynamics. It covers a very important subject: the numerical modeling of fluvial processes including turbulent flows in rivers, sediment transport, and the deformation of alluvial channels. This book is very welcome as it provides a worthy synthesis of knowledge in one of the fast growing fields of hydraulic engineering.’

‘With his background from China, studies in Europe, and practice in the United States, the author presents this subject from a unique international perspective.’

Pierre Y. Julien in JOURNAL OF HYDRAULIC ENGINEERING © ASCE. October 2008

‘… the present book is to my knowledge a unique resource for engineers and scientists interested in numerical modeling of flow and sediment transport in alluvial channels.’ George S. Constantinescu in JOURNAL OF HYDRAULIC RESEARCH vol. 46, no. 6 (2008)

'This book is one of the first to present a complete picture of the physical principles and numerical methods used in computational river dynamics.' W. Czernuszenko in ARCHIVES OF HYDRO-ENGINEERING AND ENVIRONMENTAL MECHANICS. vol. 54 no. 4 (2007)
