Bridge hydraulics

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 a "Most new roads involve the design of bridges across rivers and streams. For reasons of economy, the size of the openings must be kept reasonably small, yet must be large enough to pass floods. Getting this balance right has taxed engineers in all parts of the world for centuries. Similarly, existing bridges may have to be investigated to determine their contribution to flooding or susceptibility to scour. How can a bridge waterway be analysed and designed? Is there a hydraulic difference between a rectangular and an arched opening? By how much does a bridge exacerbate flooding upstream? How can scour be evaluated and adequate protection afforded? This book answers these questions and many more." "Bridge Hydraulics will be a valuable reference for practising engineers concerned with bridges over rivers, and will assist greatly in the production of authoritative analyses and effective designs."--Jacket This is the first book to consider both arched and rectangular waterway openings in detail and to describe all of the main methods of analysis.
