1D transient numerical simulations with a modified version of the SUTRA model (preliminary code) that accounts for variably-saturated freeze-thaw dynamics (e.g. McKenzie and Voss, 2013) to predict annual alluvial aquifer temperature dynamics using coupled fluid and heat transport physics. The model simulations were run with a modified version of SUTRA_ICE (unreleased) that accomadates a time-variable sinusiodal upper temperature boundary. This data release also includes the source code and Argus One GUI files used to build the models, though this proprietary software is not needed to run the models as described in the upper-level "readme" file.

A combination of long-term daily temperature records and depth to bedrock measurements were used to parametrize one-dimensional models of shallow aquifer vertical heat transport in Shenandoah National Park, VA, USA. Depth to bedrock can directly influence shallow aquifer flow and thermal sensitivity, but is typically ill-defined along the stream corridor in steep mountain catchments. We employed rapid, cost-effective passive seismic measurements to evaluate the variable thickness of the shallow colluvial and alluvial aquifer sediments along a headwater stream supporting coldwater-dependent brook trout (Salvelinus fontinalis) in Shenandoah National Park. The methods are fully documented in the associated journal...
