Summary of Transportation and Utility Assets Vulnerable to Fluvial Erosion Hazards in Indiana

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 10:12 PM | Dataset Last Updated: August 27, 2020 at 12:00 AM
An investigation was completed by the U.S. Geological Survey in cooperation with the Indiana Office of Community and Rural Affairs that found 1,132 transportation and utility assets in Indiana are vulnerable to fluvial erosion hazards due to close proximity to actively migrating streams. Locations of transportation assets (bridges, roadways, and railroad lines) and selected utility assets (high-capacity overhead power-transmission lines, underground pipelines, water treatment facilities, and in-channel dams) were determined using aerial imagery hosted by the Google Earth platform. Identified assets were aggregated by stream reach, county, and class. The contents of this data release include (1) a comma-delimited text file summarizing the findings of that investigation, and (2) a polyline shapefile of the investigated stream reaches, which have been attributed with the channel migration rates documented in Robinson (2013a). Together, these products are intended to help stakeholders and others identify high-risk areas where transportation and utility assets may be threatened by fluvial erosion hazards.
