This dataset includes the one-dimensional HEC-RAS water quality model simulation input and output files for two simulation discharges at the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri. Simulations were run for environmental DNA (eDNA) sample collection dates on July 07, 2020 and July 23, 2021. For each eDNA collection date, the transport of freshwater mussel eDNA from Cumberlandia monodonta 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 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.

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.

This dataset includes the one-dimensional HEC-RAS model calibration files and simulation input and output files for the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri. Simulation results were used as input for environmental DNA transport models.

This dataset includes the one-dimensional HEC-RAS model simulation input and output files for 9 simulation discharges at the Wallens Bend reach on the Clinch River near Kyles Ford, Tennessee. The Wallens Bend model has 101 cross sections on the main stem of the Clinch, 5 cross sections on the North Fork tributary, and spans approximately 4,880 m between the most upstream and most downstream cross sections. Simulations were run for environmental DNA sample collection dates between September 24, 2019 and December 15, 2021. Simulation results were used as input for environmental DNA transport models.

This dataset contains two-dimensional hydraulic models throughout the Willamette River, extending from the McKenzie River confluence, near Eugene, to the city of Newberg. The study reach is separated into five individual models to simplify tributary inflow boundary conditions and for run-time efficiency. These models were developed to assess juvenile salmonid habitat at streamflows ranging from typical low summer flows to roughly the median annual high flow along each reach. Steady-state streamflow conditions were simulated in an unsteady flow simulation by holding streamflow constant for longer periods of time. Underlying these models is a digital elevation model, which combines bathymetric lidar, collected in 2017, with boat-based sonar data. Details on model and bathymetry development, calibration, and results can be found in the accompanying Scientific Investigation Report, Development of Continuous Bathymetry and Two-Dimensional Hydraulic Models for the Willamette River, Oregon.

These datasets contain results of sediment and contaminant transport (arsenic) simulation for 100-year flood in Woodbridge watershed, NJ. The flood discharge is simulated by HEC-HMS model using 24-hours storm and runoff curve number method. HEC-RAS 2D is used to simulate flood with 48-hours duration. The External Coupler program links HEC-RAS 2D and WASP in an offline and one-way direction. The Coupler is developed in python. The source code, executable file, and users’ manual for the program are available in the External Coupler folder. Using hydrodynamic file generated by the External Coupler, WASP simulated sediment and contaminant transport in flood. This dataset is associated with the following publication: Shabani, A., S. Woznicki, M. Mehaffey, J. Butcher, T. Wool, and P. Whung. A coupled hydrodynamic (HEC-RAS 2D) and water quality model (WASP) for simulating flood-induced soil, sediment, and contaminant transport.
