GEOtop: Simulating the combined energy and water balance at and below the land surface accounting for soil freezing, snow cover and terrain effects (Invited)
Abstract
One of the most interesting characteristics of the GEOtop distributed model is the way that it treats soil freezing. The theory behind soil freezing in GEOtop is here reviewed by means of a neat thermodynamical treatment that includes a discussion of the Clausius-Clapeyron relation. Effects of soil freezing on the production of subsurface fluxes and surface runoff are presented through some simple "virtual" case study, which constitutes a possible benchmark for comparing soil freezing models. Effects of freezing and thawing is also presented in a real case study. Effects of snow-cover on the thermal evolution of soil is also presented and discussed. Eventually ways to improve GEOtop are presented and discussed.
