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...

These data sets were derived from surveys at the Missouri River and Papillion Creek Water Resource Recovery Facility outfalls on the Missouri River. Each site had three transects, one at the outfall, one 45.7 meters upstream of the outfall and one 45.7 meters downstream of the outfall. Velocity and depth data were collected using an acoustic Doppler current profiler at each transect. Elevations of water surface, bank topography, and shallow channel bed elevations were collected at each transect using survey grade Global Navigation and Satellite System instruments connected to the High Precision Real-Time Kinematic (HPRTK) correction service (https://hprtk.net). Data were processed using Velocity Mapping Toolbox:...

There is a growing interest in incorporating higher-resolution groundwater modeling within the framework of large-scale land surface models (LSMs), including new processes such as three- dimensional flow, variable soil saturation, and surface water/groundwater interactions. Conversely, complex groundwater models (e.g., the U.S. Geological Survey Groundwater-Flow Model, MODFLOW) often use simpler representations of land surface dynamics (e.g., surface vegetation, evapotranspiration, recharge) and may benefit from higher process fidelity and temporal resolutions in these inputs. This study investigates the potential of improving groundwater representation in LSMs and land surface dynamics in MODFLOW through coupling...
