Summary
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.

Purpose
Datasets were collected to aid in detecting potential scour problems and assess channel stability and hydraulic conditions in the vicinity of selected bridge sites in Montana. Cross-section data are utilized for (1) identifying and monitoring scour and erosion at bridge piers and abutments, (2) monitoring the performance of existing scour countermeasures, (3) evaluating flood infrastructure integrity, and (4) contributing to a better understanding of scour processes and the science of geomorphology as it relates to channel stability at bridge crossings. These data (2022) can assist in identifying bridges that may be at risk to scour problems.
