Flow, turbulence, and bathymetric measurements of the Missouri River at Searcys Bend, near Huntsdale, Missouri September 16, 2021
This dataset includes measurements of flow, turbulence, and bathymetry generated from multibeam bathymetry for a short reach of the Missouri River at Searcys Bend (SB) near Huntsdale, Missouri. Flow and turbulence were characterized using a Signature 1000 mounted on an anchored moving boat and an Aquadopp mounted on a tripod near the bed. Repeat bathymetric measurements were made in small patches
Supporting files for particle tracking simulations of the May 5, 2021 dye release experiment on the Missouri River at Searcys Bend, near Columbia, Missouri
This project contains data and supporting files from hydrodynamic and particle tracking models of the Missouri River at Searcys Bend developed in conjunction with an experimental dye release at the study site on March 5, 2021. The main objectives of this effort were to develop a hydrodynamic model using topographic and flow data collected in the field for subsequent use in a particle tracking mode
Field Data and Models of the Missouri River at Sheepnose Bend, near Lexington, Missouri, 2019-2021
This project includes field data and data supporting models of the Missouri River at Sheepnose (SN) bend, near Lexington, Missouri. Field datasets include a topobathymetric digital elevation model (DEM) for a 10-km reach of the Missouri River, repeat surveys of channel bathymetry from 2019-2021, water surface elevation profiles, velocity data collected with acoustic Dopper current profiler (ADCP).
Cross-sectionally averaged flow metrics from ADCP measurements of the Missouri River downstream of Wolf Point, MT during 2018-2019
This dataset contains cross-sectionally averaged flow metrics from measurements made with acoustic Doppler current profilers (ADCP) on the Missouri River near Wolf Point, MT during 2018 and 2019. Each data point represents a single-pass measurement with a boat-mounted ADCP driven from bank-to-bank along lateral transects spaced ~15 meters apart along a 33 kilometer reach. The measurements were col
Bedform distributions and dynamics in a large, channelized river: Implications for benthic ecological processes
Sand bedforms are fundamental habitat elements for benthic fish in large, sand-bedded rivers and are hypothesized to provide flow refugia, food transport, and ecological disturbance. We explored bedform distributions and dynamics in the Lower Missouri River, Missouri, with the objective of understanding the implications of these features for benthic fish habitat, particularly for the endangered pa

Performance evaluation of a channel rehabilitation project on the Lower Missouri River and implications for the dispersal of larval pallid sturgeon
In the Lower Missouri River, extensive channel modifications have altered hydraulic and morphologic conditions and reduced the river's ecological integrity. One species that has been adversely affected by these changes is the pallid sturgeon (Scaphirhynchus albus). Mainstem dams on the Missouri River restrict the upstream migration of adults and limit the downstream dispersal of larvae. Channeliza

Turbulence near a sandbar island in the lower Missouri River
River turbulence is spatially variable due to interactions between morphology of rivers and physical mechanics of flowing water. Understanding the variation of turbulence in rivers is important for characterizing transport processes of soluble and particulate materials in these systems. We present an exploratory effort to understand ecologically relevant flow patterns using measurements of mean fl

Evaluations of Lagrangian egg drift models: From a laboratory flume to large channelized rivers
To help better interpret computational models in predicting drift of carp eggs in rivers, we present a series of model assessments for the longitudinal egg dispersion. Two three-dimensional Lagrangian particle tracking models, SDrift and FluEgg, are evaluated in a series of channels with increasing complexity. The model evaluation demonstrates that both models are able to accommodate channel compl

A three-dimensional Lagrangian particle tracking model for predicting transport of eggs of rheophilic-spawning carps in turbulent rivers
Grass carp, bighead carp, and silver carp spawn in flowing water. Their eggs, and then larvae, develop while drifting. Hydraulic conditions and water temperature control spawning locations, egg survival, and the downstream distance traveled before the hatched larvae can swim for low velocity nursery habitats. Existing egg drift models simulate the fluvial transport of carp eggs but have limitation
