<br />16. Abstract
<br />The Federal Highway Administration document "Highways iT' ~he River
<br />Environment - Hydraulic and Environmental Design Considerations" was
<br />,
<br />published in 1975. It has proven to be a singularly authoritative
<br />docwnent for the desLgn of highway associated hydraulic structures in
<br />moveable boundary wa'::erways. This revised document incorporates many
<br />technological advanCES that have been made in this discipline since
<br />1975. Hydraulic problems at Jtream crossings are described in detail
<br />and the hydraulic principles of rigid and moveable boundary channels are
<br />discussed.
<br />In the United States, the average annual damage related to hydraulic
<br />problems at highway facilities on the Federal-aid system is $40 million.
<br />Damages by streams can be redvced significantly by considering channel
<br />stability. The types of river changes to be carefully considered relate
<br />to: 1) lateral bank erosion; 2) degradation and aggradation of the
<br />strea-mbed that continues over a period of years, and 3) natural short-
<br />term fluctuations of streambeo elevation that are usually associated
<br />with the passage of floods. Sediment transport, natural and manmade
<br />causes of waterway rE'sponses, stream stabilization (bed and banks),
<br />computer applications and cout1termeasures are some of the many issues
<br />covered. Case histories of typical manmade and natural impacts on
<br />waterways are analYZEd.
