Animations of particle tracking simulations of the Upper Missouri River near Wolf Point, MT

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-01-16T00:00:00Z
This dataset contains two subsets of animations corresponding to particle tracking simulations of the Upper Missouri River near Wolf Point, MT. Animations do not contain audio and depict particles moving from the top of the reach (left side) to the bottom of the reach (right side). The first subset are animations from simulations of a July 1, 2019, larval drift experiment. A total of 9 animations are included with each corresponding to the combination of 1 of 3 vertical movement methods (active60pct, active75pct, or passive) and 1 of 3 lateral eddy viscosity scenarios (LEVx0p5, LEVx1, or LEVx2). The second subset contains animations corresponding to particle simulations for the upper and lower sub-reaches of the larger model reach. A total of 96 animations are included corresponding to a combination of 1 of both reaches (upper or lower), 1 of 16 discharges (185-635 cms, at increments of 30 cms), and 1 of 3 vertical movement methods (active60pct, active75pct, or passive).
