FluOil Model and Related Datasets for Kalamazoo River, Michigan, Oil Spill: July 21 to October 31, 2010

This data release contains the FluOil software and the inputs and outputs needed to reproduce the FluOil model findings for a related publication (Li and others, 2022). The FluOil model describes the fate and transport of oil-particle aggregates (OPAs) in inland waterbodies by using particle tracking algorithms to represent the advection, dispersion, deposition, and resuspension of OPAs in turbulent flows. FluOil was applied to analyze the OPA deposition areas along a reach of the Kalamazoo River, Michigan, after the July 26, 2010, oil spill incident. Input to the FluOil model include unsteady one-dimensional hydraulics, generated using the Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.3 model, and an Excel spreadsheet to run FluOil in batch mode. Summarized outputs from 16 different simulations are provided. The input and output files are provided in the Input_Output.zip file; the executables of HEC-RAS 5.0.3 and FluOil are in the Model_Executable.zip file. Potential depositional areas of OPAs in the affected reach of Kalamazoo River over time are investigated by designating FluOil simulation scenarios. The run scenarios specify possible OPA transport properties for diluted bitumen petroleum in combinations of four critical shear stress values (0.01, 0.1, 0.3, and 0.5 Pascals) and four settling velocities (1, 5, 10, and 20 millimeters per second). Each combination fed to FluOil is simulated under the same given unsteady flow condition. Each simulation included a release of 5,000 OPAs at the spill location with a computational time step of 3 seconds. Within the river reach modeled by the HEC-RAS, the oil spill was assumed to have occurred at a location 3,188 meters downstream from the upper most station. At this location, OPAs entered at the water surface and at the midpoint of the channel. In FluOil’s coordinate system, the origination location is given as X = 3,188 meters (m), Y = 17.68 m, and Z = 0 m. Water temperature was fixed at 22 degrees Celsius.
