Design of spur-type streambank stabilization structures. Published Date: Language: English This document provides guidelines for identifying stream instability problems at highway stream crossings and for theselection and design of appropriate countermeasures to mitigate potential damages to bridges and other highway componentsat. Upper bank: The portion of the streambank above the elevation of the average water level of the stream. Streambank stabilization: Structures placed on or near a distressed streambank to control bank erosion or to prevent bank failure. Based on the above definitions, the difference between channel stabilization and streambank stabilization is.
The planning of many in-stream construction, stabilization, and restoration measures depends on the magnitude and frequency of a design flow event. Many techniques used for bank stabilization, including toe protection and surface armoring, are required to accommodate bankfull flow . Providing innovative approaches and methodologies for environmentally compatible river and streambank stabilization and restoration design. Pipeline protection at stream and river crossings. Current redirection and thalweg management to protect highway bridge abutments. Innovative construction techniques for stream stabilization works.
the slumping of soil into the stream and provides a more suitable area for planting. Instream Structures: Constructing log vanes, mud sills, channel blocks, and other structures protects the streambank and/or diverts flows toward the center of the stream. Generally, these structures are made from natural. streambank stabilization measures for highway engineers A study of erosion processes in channel bends and methods of controlling channelbank erosion in bends is reported on. FLow and erosion processes in channel bends are categorized and discussed to aid in identifying the erosion mechanisms and processes active at a particular site.

Get this from a library. Streambank stabilization measures for highway stream crossings: executive summary. [Scott A Brown; United States. Federal Highway Administration.; Sutron Corporation.] -- A summary off two reports resulting from a review of the applicability and usefulness of countermeasures used to stabilize eroding streambanks in the vicinity of roadways and at bridge crossings is.
number of measures to control or eliminate such hazards. Unfortunately, engineering belief that riprap is the best solution for mitigating stream bank erosion.
form of riverbank stabilization measure, the end result is typically a uniform, smooth channel, with no complexity. This means that there. Planning a Streambank or Shoreline Stabilization Projectoject Stream channel and shoreline erosion problems vary widely in type and scale, and there is no one measure that works in all cases.
Stabilization structures and vegetative measures should be planned and designed by a design professional with experience in this Size: 2MB. In a biotechnical streambank stabilization project, researchers visited and assessed 22 bridge and stream crossings in east half of Texas of the United States.
Researchers rarely observed streams in dynamic equilibrium if bridge structures severely interfered with the streams. Numerous streambank failures were observed and by: 6. streambank or shoreline and those that increase their resistance to erosive forces.
These measures can be combined into a system. Revetment designs do not reduce the energy of the flow significantly, so using revetments for spot protection may move erosion problems downstream or across the stream channel. Selecting streambank and shoreline File Size: 1MB.

between the spurs was occurring. The total length of streambank affected was about m, and the width of the stream at this location was about 15 m. The site was inspected on several occasions and was deemed to be a high priority for mitigation work.

Under these conditions, managers can be faced with relocating the pipe, performing localized streambank stabilization, or employing stream restoration techniques to provide long-term protection. Minimal changes to stream morphology, including minor relocations, which result in a net benefit to the aquatic ecosystem.
Stream relocations may be authorized, provided the activity: Is associated with the installation of a stream crossing or replacement of an existing crossing, and results in a net benefit to the stream morphology.
linear foot of streambank has proven to be one of the most successful bank stabilization measures used in that area.
This generally results in a height of stone between 3 and 5 feet high above the streambed. A “typical” cross-section can be specified on the drawings, along with a relatively smooth alignment to fit site conditions.
