MODFLOW-One Water Hydrologic Model integrated hydrologic-flow model used to evaluate water availability in the Osage Nation

January 5, 2023

The integrated hydrologic-flow model, called the Osage Nation Integrated Hydrologic Model (ONIHM) was developed to assess water availability in the Osage Nation. This model was developed using the MODFLOW-One Water Hydrologic Model (MF-OWHM) code. The ONIHM was discretized into an orthogonal grid of 276 rows and 289 columns, and each grid cell measured 1,312.34 feet (ft) per side, with eight variably thick vertical layers that represented the alluvial and bedrock aquifers within the study area, including the Vamoosa-Ada aquifer and other minor bedrock aquifers deposited during the Pennsylvanian Period. The ONIHM was delineated into 128 water-balance subregions based on surface watersheds, land cover, and water supply regions. These subregions were then grouped into 12 supergroups for analysis. Groundwater flow was simulated for two periods: (1) the calibrated 1950-2014 period from January 1950 through September 2014, and (2) the forecast period from October 2014 through December 2099. The calibration-period ONIHM simulated past conditions using measured or estimated inputs and the forecast-period ONIHM simulated three separate forecast conditions under constant dry, average, or wet climate conditions. This USGS data release contains all of the input and output files for the model described in the associated model documentation report (https://doi.org/10.3133/sir2019xxxx). This data release also includes the MODFLOW-OWHM 2.0 executable.
