SUTRA model used to evaluate the development of perennial thaw zones in boreal hillslopes

A generalized two-dimensional flow model using an enhanced version of the SUTRA model (in press) was developed to examine active-layer dynamics and permafrost thaw development broadly applicable to boreal headwater catchments. Coupled fluid-flow and energy transport was simulated through various hillslope conditions basally bounded by permafrost and subjected to seasonal air-temperature variation with superimposed linear warming. The model domain represents a generalized 2-dimensional 100 m-long fully-saturated cross-sectional hillside that slopes downward to the left from the hill top (at elevation 5 m) to a small stream (at elevation 0 m). The data included here represent a model archive for a set of generalized simulations, including [...]
