Thalwegs at selected study sites in the Pacific Northwest, USA, May 2023
Description
In May 2023, the U.S. Geological Survey provided training for bathymetric data acquisition and processing for the Iraq Ministry of Water Resources. The training included multibeam sonar theory, survey planning, data collection and processing, and dissemination. This data release presents the raw survey data, a digital elevation model (DEM), and a thalweg shapefile for three survey areas in the Pacific Northwest, USA (Mores Creek, Idaho; Columbia River, OR; Willamette River, OR). Additionally, metadata describes the processing steps, quality assurance and control, and an overall summary of each dataset. The bathymetry point cloud data were collected at selected study sites in the Pacific Northwest, U.S.A, May 2023 to produce a digital elevation model that was used to delineate a thalweg for each of the selected study sites. The DEM files were used to determine the best estimate of the location of the channel thalweg line for each selected study site. The thalweg is the lowest elevation along the longitudinal profile of the riverbed.
