Hydraulic model calibration equations 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 downstream water-surface slope and Manning's roughness (Manning's n) calibration equations for the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri, based on discharge and water surface elevation data collected between November 19, 2020 and August 25, 2021. Calibration was performed to produce optimal values of downstream water-surface slope and Manning's n for a one-dimensional hydraulic model of the LD reach.
