This dataset includes the Manning's roughness (Manning's n) and upstream water-surface elevation calibration equations for the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee, based on discharge and water-surface elevation data collected between April 14, 2021 and September 8, 2021. Discharge measurements were collected by USGS staff from the Columbia Environmental Research Center using an acoustic Doppler current profiler (ADCP) and Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) positioning. Calibration was performed to produce optimal values of downstream water-surface slope and Manning's roughness (Manning's n) for a one-dimensional hydraulic model of the WB reach.

This dataset includes the one-dimensional HEC-RAS water quality model simulation input and output files for three simulation discharges at the Wallens Bend reach on the Clinch River near Kyles Ford, Tennessee. Simulations were run for environmental DNA sample collection dates on September 14, 2020, August 10, 2021, and September 08, 2021. For each eDNA collection date, the transport of freshwater mussel eDNA from Epioblasma capsaeformis was simulated by specifying eDNA as an arbitrary constituent in the HEC-RAS water quality module and assigning a first order rate of decay. To account for the variation of the eDNA field samples at the upstream boundary condition, as well as the laboratory derived decay constants, we ran three model simulations for each eDNA collection date: a) the mean eDNA concentration at the upstream boundary with the mean decay constant (k), b) the mean eDNA concentration at the upstream boundary plus 1SE with the mean k minus 1SE, and c) the mean eDNA concentration at the upstream boundary minus 1SE with the mean k plus 1SE. Field collected eDNA concentrations were used as an upstream boundary condition.

This dataset includes 4 sets of velocity measurements and water-surface elevation measurements collected at the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee between April 14, 2021 and September 8, 2021. Velocity data were collected by USGS staff from the Columbia Environmental Research Center at different locations in the study reach using an acoustic Doppler current profiler (ADCP) and Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) positioning. Data were used to evaluate the calibration performance of a one-dimensional hydraulic model of the WB reach. Velocity data are provided as mean velocity at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS. Water-surface elevation data were collected by USGS staff from the Columbia Environmental Research Center using RTK GPS for the length of the study reach. Data were used to calibrate a one-dimensional hydraulic model of the WB reach. Water surface elevations are provided at distances along a stream centerline that corresponds to the one-dimensional hydraulic modeling reach in HEC-RAS.

Hydrologic and hydraulic analyses were done for selected reaches of the Grand River, Red Cedar River and Sycamore Creek near Lansing, Michigan. To update and expand a portion of the Federal Emergency Management Agency detailed Flood Insurance Study, the U.S. Geological Survey (USGS) and the City of Lansing initiated a cooperative study. The study comprised a 3.2-mile reach of the Grand River, a 30.2-mile reach of the Red Cedar River, and a 12.0-mile reach of Sycamore Creek. Historical streamflow data from multiple streamgages, Grand River at Lansing, MI. (USGS station number 04113000), Red Cedar River at East Lansing, MI. (USGS station number 04112500), Red Cedar River near Williamston, MI. (USGS station number 04111379), and Sycamore Creek at Holt Road near Holt, MI. (USGS station number 04112850) along with regional regression equations were used to estimate instantaneous peak streamflows for floods with 10-, 4-, 2-, 1-, 0.2-percent, and 1-percent plus annual exceedance probabilities. The 1-percent plus flood elevation is defined by the Federal Emergency Management Agency as a flood elevation derived by using streamflows that include the average predictive error for the regression equation streamflow calculation for the Flood Risk project. This error is then added to the 1-percent annual exceedance probability flood streamflow to calculate the 1-percent plus streamflow. The annual exceedance probability streamflows were then used in a Hydrologic Engineering Center-River Analysis System step-backwater model to determine water-surface elevation profiles and flood-inundation boundaries for the 10-, 4-, 2-, 1-, 0.2-percent, and 1-percent plus annual exceedance probability floods, and a regulatory floodway, along a selected reach of each stream. Each hydraulic model was calibrated to the current stage-streamflow relations at each streamgage. Flood-inundation boundaries for the 1- and 0.2-percent annual exceedance probability floods and a regulatory floodway were mapped for each stream.
