Groundwater flow and SNTEMP stream temperature historical model (2019-2023)

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:15 PM | Dataset Last Updated: December 31, 2024 at 12:00 AM
A historical conditions MODFLOW6 and SNTEMP model was developed to simulate groundwater flows and instream temperatures in Beaver Creek, Alaska during the study period and time just prior to the study. Model parameter estimation was performed via history matching of groundwater levels, instream flows and stream temperatures for 2019–2023. This data release contains a version of the historical model built from the best parameter set generated during the history matching. The history matching and model development workflows are archived in the "Groundwater flow and SNTEMP stream temperature model build and history matching workflows" child item associated with this data release. The version of the model included in this child item is the version that was used to generate the historical model results presented in the associated publication "Simulating present and future Groundwater/Surface-water interactions and stream temperatures in Beaver Creek, Kenai Peninsula, Alaska". This data release includes the model input files, executable files, and output files for that historical model.
