Available in PDF, EPUB and Kindle. Book excerpt: The models used to predict the depth of scour that might occur in a river when a bridge is constructed across it were based on laboratory data. Within the decade of the 1980s, the Federal Highway Administration encouraged the states to collect field data on flooding and its effect on bridges. These data were used to verify the models for those conditions and geographic areas for which the data were applicable. High water during floods is the test of such models. Thus, after the severe flood in November 1985, as much information as possible was collected and compiled about the flood waters, the geology of the site, the configuration of the river and its flood plain, the bridge, and the damage done by the flood at four sites. Some of the data were used to calculate hydraulic parameters, and depths of scour; and the sediments collected were processed to determine their engineering properties. At least a year after the calculations were made, the Federal Highway Administration issued a technical advisory (1) on scour at bridges which contained recommendations that would have changed the results had they been available when those calculations were made. It was recognized that the information collected in Virginia was limited in scope relative to the tremendous variability in characteristics and conditions that exist for rivers throughout the United States. Thus, in order to cooperate in a regional to national effort, this information was transmitted to the Hydraulics Section of the Federal Highway Administration where it was used to verify and modify the predictive models.

Book excerpt: This document, Hydraulic Engineering Circular No. 18 (HEC-18), contains the state-of-knowledge and practice for dealing with scour at highway bridges. The procedures for designing new, replacement and rehabilitated bridges to resist scour are presented. Procedures are presented for evaluating the scour vulnerability of existing bridges as well as inspecting bridges for scour. The use of countermeasures to protect bridges evaluated as failure prone due to scour is also presented. This document replaces the Federal Highway Administration (FHWA) publication "Interim Procedures for Evaluating Scour at Bridges," which was issued with FHWA Technical Advisory 5140.20, "Scour at Bridges," in September 1988.
Download or read book Bridge Pressure Flow Scour for Clear Water Conditions written by U.s. Department of Transportation and published by CreateSpace. This book was released on 2015-03-10 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges are a vital component of the transportation network. Evaluating their stability and structural response after a flood event is critical to highway safety. Bridge studies are usually designed with an assumption of an open channel flow condition, but the flow regime can switch to pressure flow when the downstream edge of a bridge deck is partially or totally submerged during a large flood. Figure 1 shows a bridge undergoing partially submerged flow in Salt Creek, NE, in June 2008. Figure 2 shows a totally submerged flow in Cedar River, IA, in June 2008, which interrupted traffic on I-80. Unlike open channel flows, these pressure flows create a severe scourability potential because scouring the channel bed is one of the only ways to dissipate the energy when passing a given discharge in pressurized flow. Although most bridge scour events are due to live bed scour, a maximum scour depth often results from clear water flows with a critical approach velocity for bedload motion. For bridge safety, this report emphasizes the equilibrium maximum scour of pressure flows in extreme clear water conditions. The objectives of the study were to collect a detailed high-quality dataset of pressure flow scour at a model bridge and to develop an analytical solution for pressure flow scour based on mass and energy conservation laws. To these ends, existing results in the literature were reviewed, and knowledge gaps were identified. Next, a series of flume experiments were conducted to examine the existing methods and test new hypotheses on bridge pressure flow scour. After, bridge flows were divided into three cases, and the mass and energy conservation laws were applied to each case, leading to hypotheses for pressure flow scour predictions. The hypotheses were tested with the flume data. In this report, an example procedure for calculating the maximum scour depth and scour profile is presented along with recommended research needs.
