“…It is now recognized as a hot topic in permafrost studies . As emphasized above, cryohydrogeological modeling is vital for biogeochemical studies of boreal areas, but there are many other potential fields of application of cryohydrogeological models, such as geotechnics, long‐term storage of nuclear waste, water resources in cold regions, thermal transfer around pipelines in cold regions, infrastructure stability and geothermics in cold regions …”

“…15,16 It is now recognized as a hot topic in permafrost studies. 4 As emphasized above, cryohydrogeological modeling is vital for biogeochemical studies of boreal areas, but there are many other potential fields of application of cryohydrogeological models, such as geotechnics, 17 long-term storage of nuclear waste, [18][19][20] water resources in cold regions, 21,22 thermal transfer around pipelines in cold regions, 23,24 infrastructure stability [25][26][27] and geothermics in cold regions. 28 One of the major difficulties in cryohydrogeological modeling lies in the fine temporal and spatial resolution needed to numerically solve the equations involved.…”

To quantify the impact of evapotranspiration phenomena on active layer dynamics in a permafrost‐dominated forested watershed in Central Siberia, we performed a numerical cryohydrological study of water and energy transfer using a new open source cryohydrogeology simulator, with two innovative features: spatially distributed, mechanistic handling of evapotranspiration and inclusion of a numerical tool in a high‐ performance computing toolbox for numerical simulation of fluid dynamics, OpenFOAM. In this region, the heterogeneity of solar exposure leads to strong contrasts in vegetation cover, which constitutes the main source of variability in hydrological conditions at the landscape scale. The uncalibrated numerical results reproduce reasonably well the measured soil temperature profiles and the dynamics of infiltrated waters revealed by previous biogeochemical studies. The impacts of thermo‐hydrological processes on water fluxes from the soils to the stream are discussed through a comparison between numerical results and field data. The impact of evapotranspiration on water fluxes is studied numerically, and highlights a strong sensitivity to variability in rooting depth and corresponding evapotranspiration at slopes of different aspect in the catchment.

“…For water migration during freezing, we believe that Takashi's equation has already concluded the water transfer influence. In addition, for the numerical model of frost heave, which combines water transfer process, the readers can refer to Lai et al (2005) and Tan et al (2011). Based on our model, we present some examples in the following section.…”
