    countermeasure designs for application to scour critical bridges. This handbook presents recommended guidelines for scour countermeasure design and planning for bridges in New Jersey. The handbook has been prepared on the basis on an extensive review of all available literature on scour countermeasure for bridge foundations. Highway bridges have been designed and built since the advent of the wagon, and the general structure types used and described in this chapter are not likely to change. That being said, there are areas where these structure types can be improved—hence the need for future research. It is this author's opinion that the research needs for highway bridges (and for that matter, bridges of all.

Thus, predicting scour depth is an essential step in designing bridges. This paper is a comprehensive review of local scour depth estimation methods around pile groups.

    General Scour Background Info • In completed Stage I & Stage II Scour Evaluation –Identified State Owned Bridges as Scour Critical out of ~ State Owned Bridges ( County Owned Bridges out of ~ County Bridges) • At FHWA request developed two items: 1. Scour Plan Of Action (POA) 2. Scour Countermeasure Program. -The Scour Critical Category (A, B, or C)of scour critical bridgesare designated by color.-Specific symbol shapes differentiate between county and township owned bridges.-A pop-up dialog box containing additional information, including a hyperlink to the Scour Critical Bridge Monitoring Log, is available for each bridge by clicking on the bridge location symbol.

Rapid-estimation method for assessing scour at highway bridges based on limited site data by Stephen R. Holnbeck Download PDF EPUB FB2

A method was developed for rapid estimation of scour depths at highway bridges based on limited site data that could be obtained at a site in a matter of hours rather than the several days or longer that is required by more detailed methods. Limited site data were used to develop a method for rapid estimation of scour at highway bridges.

The estimates can be obtained in a matter of hours rather than several days as required by more-detailed methods. Such a method is important because scour assessments are needed to identify scour-critical bridges throughout the United States.

better known as the Rapid-Estimation Method for Assessing Scour at Highway Bridges Based on Limited Site Data (Holnbeck and Parrett ). The U.S. Army Engineer Research and Development Center.

The scour assessment was conducted by using the Rapid Estimation Method for Limited Site Data developed by the U.S. Geological Survey. This method allows an estimate of the scour depth to be made in a time-effective manner by using data that can be easily collected or estimated during a brief bridge site.

Holnbeck and Charles Parrett Memorandum--Subject: Summary of the Bridge Scour Assessment Work Group. Method for rapid estimation of scour at highway bridges based on limited site data Limited site data were used to develop a method for rapid estimation of scour at highway bridges.

The estimates can be obtained in a matter of hours rather than several days as required by more-detailed methods. Use of the rapid-estimation method should be limited to individuals having experience in bridge scour, hydraulics, and flood hydrology and some training in use of the method.
