Izbicki 2019 Publication Scientific Investigations Report 2019-5091 Reston, VA, USA U.S. Geological Survey https://doi.org/10.3133/sir20195091 MODFLOW-2000 was used within the AnalyzeHOLE program--an integrated wellbore flow analysis tool (https://doi.org/10.3133/tm4F2)--to simulate the 2-D radial flow to each of six wells within three basins at the Fort Irwin National Training Center in San Bernardino County, California. Wellbore flow was simulated for each well by using AnalyzeHOLE to evaluate aquifer properties and heterogeneity. Horizontal layers within the model (hydrogeologic units) were defined based on lithologic and geophysical logs from each well and adjusted during calibration. The majority of the wells were installed in previously underdeveloped or minimally developed groundwater basins. The information gathered from the models provides a basis for developing and constraining basin-scale hydrogeologic-framework and groundwater-flow models that will be used to further evaluate water resources in each groundwater basin. This USGS data release contains all of the input and output files for the AnalyzeHOLE analysis of six wells described in the associated U.S. Geological Survey Scientific Investigations Report 2019-5091 (https://doi.org/10.3133/sir20195091). This groundwater model was created by AnalyzeHOLE to simulate wellbore flow and evaluate aquifer properties and heterogeneity in wells at Fort Irwin National Training Center, California. The development of the model input and output files included in this data release were used in wellbore-flow analysis documented in U.S. Geological Survey Scientific Investigations Report 2019-5091 (https://doi.org/10.3133/sir20195091). Support is provided for correcting errors in the data release and clarification of the modeling conducted by the U.S. Geological Survey. Users are encouraged to review the associated report (https://doi.org/10.3133/sir20195091) and the AnalyzeHole documentation (https://doi.org/10.3133/tm4F2) to understand the purpose, construction, and limitations of this model. The models, along with pre- and post-processing tools, will run successfully only if the original directory structure is correctly restored. The model archive is broken into several pieces to reduce the likelihood of download timeouts. Instructions for reconstructing the original directory structure and running the models included in this data release and described in the associated report can be found in the readme.txt ASCII file which can be downloaded as part of this data release. 20151218 20170524 publication date Complete Not planned -117.0780 -116.6600 35.4500 35.2610 ISO 19115 Topic Category geoscientificInformation inlandWaters environment USGS Thesaurus usgsgroundwatermodel MODFLOW-2000 Groundwater InlandWaters Groundwater Model 2-D radial flow wellbore-flow analysis AnalyzeHOLE USGS Metadata Identifier USGS:9a0c7cd8-ab20-451a-9f6c-40ac226a5344 Geographic Information Names System California Fort Irwin National Training Center San Bernardino County Goldstone Basin Nelson Basin Superior Basin None.

Each model was calibrated by adjusting the hydraulic conductivity of each hydrogeologic unit (HGU) to best match measured drawdown and wellbore-flow data collected from each test well under pumping conditions. For the purposes of this report, the intent of the flow logging was to characterize bulk hydraulic properties of major HGUs. Relatively small fluctuations in flow contribution within a given unit were not necessarily explicitly simulated, as long as the overall HGU properties were suitable to achieve a satisfactory calibration with respect to aquifer transmissivity, HGU hydraulic conductivity, wellbore-flow contribution and drawdown in response to pumping. No formal logical accuracy tests were conducted Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record, the associated report (https://doi.org/10.3133/sir20195091) and the AnalyzeHole documentation (https://doi.org/10.3133/tm4F2) for additional details.
