This dataset contains two separate sets two- and quasi-three-dimensional hydrodynamic model outputs from the Flow and Sediment Transport with Morphologic Evolution of CHannels (FaSTMECH) hydrodynamic model in the open-source binary Visualization Toolkit (VTK) format (https://vtk.org/). The first dataset set contains outputs from simulations of flow conditions of 348 cms as measured on July 1, 2019, during a larval drift experiment conducted on the Upper Missouri River near Wolf Point, MT. The second dataset contains hydrodynamic model outputs from simulations at the same site for flows in the range of 185-635 cms at increments of 30cms. Files can be opened using the open-source software program Paraview: (https://www.paraview.org/).
