This data release contains steady-state hydraulic input files for the FluOil model (Zhu and others, 2022) that describe the lower St. Croix River between St. Croix Falls, Wisconsin, and Stillwater, Minnesota. These files are derived from the results of a steady-state one dimensional (1D) hydraulic model of the river reach at three discharges (10,000, 20,000, and 35,000 cubic feet per second (cfs)) and include the flow depth, velocity magnitude, and shear velocity along the model domain. A constant temperature of 20 degrees Celsius is also specified. The hydraulic model used to generate this dataset was originally adapted from an existing U.S. Army Corps of Engineers Hydrologic Engineering Center River Analysis System...
Model Archive and Hydraulic and Fluvial Egg Drift Simulator (FluEgg) Results for Simulations of Grass Carp Eggs and Larval Drift in the Lower Sandusky River, Ohio
The U.S. Geological Survey simulated the drifts of grass carp eggs in the lower Sandusky River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) (Garcia and others, 2013; Zhu, 2019). The hydraulic inputs used in the FluEgg simulations were generated using a one-dimensional (1D) Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.3 model of the lower Sandusky River (HEC-RAS, 2021). This data release contains an archive of the relevant files to document and run the HEC-RAS and FluEgg simulations of the lower Sandusky River as well as the simulation outputs. This ScienceBase page contains two child items, the first of which provides the HEC-RAS information and the second of which provides the FluEgg...
This page describes simulations of the drift of grass carp eggs in the lower Sandusky River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) model version 3.1.0 (Garcia and others, 2013; Zhu, 2019). Inputs and outputs from 127 simulations are included. FluEgg simulated transport and dispersion of grass carp eggs from a selected location using the spawning time and age of the eggs collected during an ichthyoplankton survey on July 12, 2017 (King and Kočovský, 2021). Drifts of grass carp eggs were simulated for a reach of the lower Sandusky River from the Ballville Dam to the confluence with Muddy Creek Bay. The Ballville Dam, which was a physical barrier to upstream migrating fishes, was in place during the...

This data release contains the models and their inputs and outputs needed to reproduce the findings for the publication by Soong and Over (2022), "Effect of Uncertainty of Discharge Data on Uncertainty of Discharge Simulation for the Lake Michigan Diversion, Northeastern Illinois and Northwestern Indiana." These data were developed in cooperation with the U.S. Army Corps of Engineers, Chicago District, for the Lake Michigan Diversion Accounting program. Data are provided in four zip files and one MS Word file. The MS Word file 4.ReadMe.HSPF_Recalibrations_with_17TimeSeriesPairs.docx documents the recalibration of the Hydrological Simulation Program - FORTRAN (HSPF) model with discharge time series pairs that characterize...

This page contains an unsteady-state one-dimensional (1D) river and 3 two-dimensional (2D) bays Hydrologic Engineering Center - River Analysis System (HEC-RAS) model (version 5.0.3) simulations for the lower Sandusky River, Ohio from July 10 – 13, 2017, during the passage of a storm. The upstream end of the 1D model domain is located 2 km upstream from the U.S. Geological Survey (USGS) stream gage at Sandusky River near Fremont, Ohio (station number 04198000). The downstream end of the 1D model is at the confluence of Sandusky River with Muddy Creek Bay. The stream gage at Sandusky River near Fremont, Ohio, is located 3.8 km upstream from Ballville Dam and 25.6 km upstream from the confluence of Sandusky River with...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
