Channel geometry for upstream and downstream cross sections at selected bridge sites in Montana, 2022

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 06:01 AM | Dataset Last Updated: May 08, 2023 at 12:00 AM
The U.S. Geological Survey, in cooperation with the Montana Department of Transportation (MDT), collected cross-section data on the upstream and downstream sides at 18 sites involving 20 bridges in Montana during the 2022 calendar year. The purpose of the data collection is to determine if scour and channel instability occur in the vicinity of the bridge structures. Data were processed, analyzed, and compiled for bridge scour monitoring, facilitating better understanding, documentation, and prediction of scour processes.
