Model introduction

GIPL(Geophysical Institute Permafrost Laboratory) is an implicit finite difference transient one-dimensional heat flow model. The model simulates ground temperature dynamics and the depth of the active layer by solving non-linear heat equation with phase change numerically. The model employs the Enthalpy method which does not require explicit treatment of the freeze/thaw moving boundary. In this model the process of freezing or thawing is occurring in accordance with unfrozen water content and soil thermal properties, and depends on the degree of soil saturation.
