One-dimensional HEC-RAS hydraulic model simulation files for the Lazy Day reach of the Big Piney River, near St. Robert, Missouri

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-10-21T00:00:00Z
This dataset includes the one-dimensional HEC-RAS model simulation input and output files for 15 simulation discharges at the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri. The Lazy Day model has 94 cross sections and spans approximately 2,327 m between the most upstream and most downstream cross sections. Simulations were run for environmental DNA sample collection dates between March 13, 2020 and May 12, 2022. Simulation results were used as input for environmental DNA transport models.
