    • Channel geometry for upstream and downstream cross sections at selected bridge sites in Montana, 2021

    Metadata Updated: January 21, 2026

    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 26 sites involving 29 bridges bridges in Montana during the 2021 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 scour monitoring, facilitating better understanding, documentation, and prediction of scour processes.
