Streambed Scour at Bridges in Alaska

Streambed scour is the leading cause of bridge failure in the United States resulting in over 60 percent of all failures. The Alaska Science Center, in cooperation with the Alaska Department of Transportation and Public Facilities and the Alaska Railroad, is researching streambed scour through scour monitoring, hydraulic modeling, and data collection during high flows.

Sounding Cross Section Surveys at Alaska Bridge Crossings

Since 1993 the U.S. Geological Survey (USGS) has worked with the Alaska Department of Transportation and Public Facilities (ADOT&PF) to provide hydraulic assessments of scour for bridges throughout Alaska. As part of this effort, repeat channel cross section surveys, or channel soundings, have been collected at either the upstream or downstream side of bridges on an annual or as needed basis. Stre

Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023

In July 2023, the U.S. Geological Survey Alaska Science Center (USGS ASC) and the USGS Idaho Water Science Center (IDWSC), in cooperation with Alaska Department of Transportation and Public Facilities (AKDOT & PF), completed bathymetric and topographic surveys at four highway bridge structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR).

Tabular Input/Output Data and Model Files for 19 Two-Dimensional Hydraulic Models for Streambed Scour Evaluations at Selected Bridge Sites in Alaska, 2016-2017

This data release includes tabular surveyed and interpolated elevation data, the processed computational mesh, and model output data used in scour evaluations. The methods of deriving these datasets and using them to calculate scour are described in the associated Scientific Investigations Report "Scour evaluations and conditions at selected bridge sites in Alaska, 2016-2017".

Real-time pier scour monitoring and observations at three scour-critical sites in Idaho, water years 2020–22

To observe real-time pier scour at three scour-critical sites in Idaho, the U.S. Geological Survey, in cooperation with Idaho Transportation Department, installed and operated fixed real-time (15-minute interval) bed elevation scour sonar sensors at three bridge locations associated with U.S. Geological Survey streamflow gaging stations for water years 2020 through 2022.

Streambed scour evaluations and conditions at selected bridge sites in Alaska, 2012

Streambed scour potential was evaluated at 18 river- and stream-spanning bridges in Alaska that have unknown foundation details or a lack of existing scour analysis. All sites were evaluated for stream stability and long-term scour potential. Contraction scour and abutment scour were calculated for 17 bridges, and pier scour was calculated for 7 bridges that had piers. Vertical contraction (pressu

Evaluation of streambed scour at bridges over tidal waterways in Alaska

The potential for streambed scour was evaluated at 41 bridges that cross tidal waterways in Alaska. These bridges are subject to several coastal and riverine processes that have the potential, individually or in combination, to induce streambed scour or to damage the structure or adjacent channel. The proximity of a bridge to the ocean and water-surface elevation and velocity data collected over a
