The design of bridges across rivers and streams is a major component of many civil engineering projects. The size of waterways must be kept reasonably small for reasons of economy and yet be large enough to allow floods to pass. Bridge Hydraulics is the first book to consider both arched and rectangular waterway openings in detail and to describe all of the main methods of analysis. With clear examples and relevant case studies, using both laboratory models and full- size bridges in the field, it is not only a thorough and accessible introduction to bridge hydraulics, but also a guide that will enable engineers to produce authoritative analyses and more effective designs.

The Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System is intended to be the successor the current steady-flow HEC-2 Water Surface Profiles Program as well as provide unsteady flow, sediment transport, and hydraulic design capabilities in the future. A common data representation of a river network and bridge data is used by all modeling methods. This paper presents the bridge modeling approach, available methods, and research results on flow transitions and associated modeling guidelines.

Most analyses of bridge hydraulics for flood flows are performed using the Army Corps of Engineers HEC-RAS (Hydrologic Engineering Centers River Analysis System) computer program. This study was carried out to compare results of HEC-RAS bridge modeling with experiments performed in a laboratory flume. The study was intended to add some insight into the effect of bridge hydraulic features such as ineffective flow regions, weir overflow and flow through skewed bridges. This insight should be useful for bridge engineers in HEC-RAS bridge modeling endeavors. A laboratory flume was constructed specifically for this project. The flume cross section has a main channel region and relatively wide left and right overbank regions. Different bridge scenarios were modeled. Froude number similarity was used to "scale up" model parameters and create prototype HEC-RAS hydraulic models simulating laboratory model conditions. Water surface profiles were compared for corresponding HEC-RAS and laboratory results.
