Future conditions model scenarios for MODFLOW6 and SNTEMP models were developed to simulate groundwater flows and instream temperatures in Beaver Creek, Alaska from 2019-2050 using climate data from climate projections. The scenario models used updated climate variables with the best set of model parameters selected for the historical model via history matching of groundwater levels, instream flows and stream temperatures for 2019–2023. This data release contains scripts to build each model scenario and output from running each scenario. The versions of the model scenarios included in this child item are the versions that were used to generate the model scenario 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 those model scenarios.
