“…In addition to changing the optical properties in disturbed areas, conditions are formed for changing the water content in the near-surface soil horizons [35]. Such changes in moisture content directly depend on the degree of disturbance of the vegetation cover and soil, including the disturbance of its structural organization.…”

We investigated changes in the temperature regime of post-fire and post-technogenic cryogenic soils of Central Siberia using remote sensing data and results of numerical simulation. We have selected the time series of satellite data for two variants of plots with disturbed vegetation and on-ground cover: natural ecosystems of post-fire plots and post-technogenic plots with reclamation as well as dumps without reclamation. Surface thermal anomalies and temperature in soil horizons were evaluated from remote data and numerical simulation and compared with summarized experimental data. We estimated the influence of soil profile disturbances on the temperature anomalies forming on the surface and in soil horizons based on the results of heat transfer modeling in the soil profile. According to remote sensing data, within 20 years, the thermal insulation properties of the vegetation cover restore in the post-fire areas, and the relative temperature anomaly reaches the level of background values. In post-technogenic plots, conditions are more “contrast” comparing to the background, and the process of the thermal regime restoration takes a longer time (>60 years). Forming “neo-technogenic ecosystems” are distinct in special thermal regimes of soils that differ from the background ones both in reclamated and in non-reclamated plots. An assumption was made of the changes in the moisture content regime as the main factor causing the long-term existence of thermal anomalies in the upper soil horizons of disturbed plots. In addition, we discussed the formation of transition zones (“ecotones”) along the periphery of the disturbed plots due to horizontal heat transfer.

“…In the context of the diversity of soil properties, the issue of mathematical modeling based on ground-based and remote sensing data is urgent [7,27,[31][32][33][34][35]. Available models of heat and moisture transfer in soil under freezing and thawing conditions take into account the moisture conductivity of soil [36][37][38][39].…”

“…( 2012), ısısal yayınımın jeolojik oluşum süreçlerinde önemli faktör olduğunu, 26 m toprak derinliğinde ısısal yayınımın 1.1•10 −6 m 2 sn -1 ile 1.6·10 −6 m 2 sn -1 (veya 0.011-0.016 cm 2 sn -1 ) arasında değiştiğini göstermişlerdir.

“…Genel olarak, ısısal yayınım katsayısı iklim faktörleriyle beraber, nem, hacim ağırlığı, organik madde miktarı, toprak bünyesi (kil, silt, kum), tuz miktarı gibi toprak özelliklerine önemli düzeyde bağlı olup; nem, kil, tuz miktarı, hacim ağırlığı, tuz miktarıyla pozitif, organik madde miktarıyla ise negatif ilişki göstermektedir. Fakat toprak özelliklerinin düzensiz değişimi ve bir birine olan karşılıklı etkisi; ayrıca her bir özelliğin ısısal yayınıma etkisinin belirlenmesini zorlaştırmakta ve bazı durumlarda imkansız yapmaktadır (Tikhonravova, 2007;Arkhangel'skaya ve Umarova, 2008;Arkhangelskaya ve Lukyashchenko, 2018;Arkhangelskaya, 2020). Bu ise, kil, kumlu killi tın, kumlu tın, killi tın bünyeye sahip araştırma profillerinde ısısal yayınım katsayılarının farklı değerlere sahip olmasına neden olmaktadır.…”

“…Ayrıca, toprağın hem ısı iletkenliği hem de ısı kapasitesi toprak nem içeriğine göre önemli düzeyde değiştiği için, toprakların ısısal yayınımı büyük ölçüde nem içeriğine de bağlıdır. Herhangi bir toprağın farklı nem içeriğine sahip olması durumunda, ısısal yayınımın değişim aralığı, toprak bünyesine, hacim ağırlığına ve organik madde içeriğine bağlı olarak değişmektedir (Parikh ve ark., 1979;Abu-Hamdeh, 2003;Roxy ve ark., 2010;Arkhangel'skaya ve ark., 2015;Arkhangelskaya ve Lukyashchenko, 2018;Arkhangelskaya, 2020). Toprağın ısısal özelliklerinden biri olan hacimsel ısı kapasitesi, toprağın hacimsel su içeriği, hacim ağırlığı ve organik karbon konsantrasyonuyla pozitif bir ilişkiye sahip olabilir (Abu-Hamdeh, 2003;Adhikari ve ark., 2014;Lu ve ark., 2014).…”

A numerical model of heat conduction and water mixing was developed, enabling a quantitative description of water temperature variability at a spring outflow. The study examined the Czarny Potok spring, located in the Pieniny Mountains of southern Poland, which was the subject of a 4-year series of water temperature observations. The presented model describes the soil and water environment in the immediate vicinity of the spring, assuming that the spring water temperature is shaped by the mixing of water flowing through the shallow zone that experiences seasonal fluctuation and the deeper neutral zone. It was also assumed that the conductive heat flow in the tested medium is conditioned by seasonal heating and cooling of the land surface. The thermal diffusivity of the bedrock was calculated on the basis of the phase shift and the attenuation of thermal amplitude at different depths, based on long-term monitoring of soil temperature. The heat conduction and water mixing models enabled calculation of the water temperature at the outflow. The obtained results are close to the empirical spring water temperatures. The estimated mean error was 0.075 °C and the mean absolute error was 0.188 °C. The results of the calculations suggest that the tested spring is recharged primarily by water flowing through the seasonal fluctuation zone (75%), while the remaining 25% captures a deeper circulation system associated with the neutral zone.
