Summary

The North Carolina Department of Transportation (NCDOT) began work on a highway widening project on Interstate-26 (I-26) in January 2020. The French Broad River flows adjacent to and under I-26 in the project area, located in Buncombe County of North Carolina. The NCDOT identified channel and streambank morphology as a potential indicator they were interested in monitoring at three focus areas to track impacts from construction activities. The U.S. Geological Survey (USGS) in cooperation with the NCDOT conducted a single-beam bathymetric survey of one of the three focus areas in June of 2019, approximately seven months before construction was to begin. The survey extended from 300 meters (m) upstream to 500 m downstream of the I-26 [...]

Purpose

Bathymetric data were collected to characterize stream-bed morphology and benthic habitat in stream reaches upstream and downstream of the I-26 bridge. This first survey of the project sets a baseline to which future surveys will be compared. Subsequent bathymetric surveys over the same river reach of the French Broad River will allow for periodic geomorphological assessments, allowing for a spatial and temporal assessment of morphological change the I-26 widening project may have on the French Broad River.
