River Hydraulics Book

This guidebook introduces the basic principles and technical procedures for the analysis of open channel flows in natural river systems. Pragmatic methods for the appropriate application and selection of numerical models for river engineering investigations are presented here with a minimal amount of theory. Chapters review multidimensional flow analysis, unsteady flow, steady flow-water surface profiles, and water surface profiles with movable boundaries. The progressive order of these technical chapters illustrates how each successive approach derives from the prior approach. Each chapter provides guidelines, data requirements, computational procedures, and examples. Past experiences and results of previous numerical model applications to river hydraulics and corresponding field observations reveal key information for detecting and avoiding problems in planning, performing, and reporting future studies.
