Niobrara River Bathymetric and Topographic Surveys to Assess Topobathymetric Lidar Accuracy, 2020 The Niobrara River is a National Scenic River in northern Nebraska. The Niobrara River is characterized by a sand channel with areas of gravel and bedrock. Bathymetric and topographic surveys were completed at five sites (Norden, Meadville, Mariaville, Spencer, and Niobrara) on the Niobrara River in August 2020. The bathymetric data were collected using Acoustic Doppler Current Profilers (ADCPs) attached to kayaks. The ADCP data were collected on transects and between the transects following the flow of the river at each site. Topographic data including water surface elevations were collected with survey grade Global Navigation Satellite Systems (GNSS). A temporary reference point was established at each of...
