In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction bathymetric survey of the streambed in June 2019 (Whaling and Wagner, 2021) within a one-kilometer reach of the FBR at the bridge construction site. A canoe-based repeat bathymetric survey was collected with a single-beam echosounder approximately 18 months after construction began, with the purpose to monitor geomorphological changes to the streambed and inform the NCDOT of potential impacts...

A canoe-based repeat bathymetric survey was collected with a single-beam echosounder approximately 23 months after construction began, with the purpose to monitor geomorphological changes to the streambed and inform the NCDOT of potential impacts...
In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. To track potential impacts from construction activities, the U.S. Geological Survey (USGS) in cooperation with the NCDOT conducted a single-beam bathymetric survey in June of 2019, approximately seven months before construction began. The survey extended from 300 meters (m) upstream to 500 m downstream from the I 26 bridge located south of Asheville, North Carolina. Depth data were collected using a CEESCOPE single-beam echosounder mounted to a canoe. Position and elevation data were...

A canoe-based repeat bathymetric survey was collected with a single-beam echosounder approximately 30 months after construction began, with the purpose to monitor geomorphological changes to the streambed and inform the NCDOT of potential impacts...
In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S. Geological Survey (USGS) in cooperation with the NCDOT, conducted a streambank light detection and ranging (lidar) survey of the streambanks of the French Broad River in November of 2019, approximately two months before construction began. The survey extended from 300 meters (m) upstream to 700 m downstream from the bridge. Two georeferenced lidar scans were collected; one of the right-descending bank and one of the left-descending bank. Three-dimensional points of the streambank...
