A METHOD TO EVALUATE THE IMPACT OF URBANIZATION ON GROUND TEMPERATURE EVOLUTION AT REGIONAL SCALE

open access: yesRudarsko-geološko-naftni Zbornik, 2018
The replacement of natural soil and vegetation by artificial surfaces increases temperatures of the surrounding air and subsurface throughout the year, because of indirect solar heating of urban structures, building heat losses and land use change.

Response of Permafrost Thermal State to Global Climatic Change in Urbanised Landscapes, Yakutsk, Russia

open access: yesLand, 2022
A study was undertaken to investigate the structure and condition of urban permafrost in the city of Yakutsk. The response of permafrost to recent climate change was assessed for a Shergin Shaft site in a cryogenic landscape.

The effect of the shape of gaps on microenvironmental conditions and seedling recruitment in Molinietum caeruleae meadows

open access: yesActa Agrobotanica, 2015
Cessation of the management of semi-natural habitats such as grasslands and meadows contributes to secondary succession and encroachment of native and alien tall-growing perennials, large tussock grasses, shrubs, and trees. Thus, the formation of gaps in

Seasonal InSAR Displacements Documenting the Active Layer Freeze and Thaw Progression in Central-Western Spitsbergen, Svalbard

open access: yesRemote Sensing, 2021
In permafrost areas, the active layer undergoes seasonal frost heave and thaw subsidence caused by ice formation and melting. The amplitude and timing of the ground displacement cycles depend on the climatic and ground conditions. Here we used Sentinel-1

Establishment and Verification of a Thermal Calculation Model Considering Internal Heat Transfer of Accumulated Water in Permafrost Regions

open access: yesFrontiers in Earth Science, 2021
Water accumulation in permafrost regions causes a heavy thermal impact on the frozen layer, thereby leading to its degeneration. First, based on the real heat transfer process, this study proposes relevant hypotheses and governing equations for heat ...

Analysis of ground temperature variations on the basis of years-long measurements [PDF]

open access: yesИнженерно-строительный журнал, 2017
The article deals with results of the analysis of years-long measurements of the ground temperatures, for example: Russia, Moscow. Data are given on variations of the ground temperatures in the course of a year, at a 10-days interval, in two plots of ...

Deep ground temperatures

open access: yes, 2000
Some 60 holes drilled for hydrocarbon exploration in the Mackenzie valley afford the opportunity to obtain precise measurements of deep permafrost thicknesses (depth to 0°C) and ground temperatures, and are presented here on maps and graphs. Permafrost thickness is less than 100 m in the Mackenzie Delta, and up to 663 m in the adjoining Tuktoyaktuk ...

Ground temperature estimations for Bolu, Turkey

open access: yesEnvironmental Monitoring and Assessment, 2011
The approximation of the soil temperature profile may be considered for many energy, environmental, and agriculture applications. In this study, temperature approximation model of ground in Bolu is developed. Unsteady state one-dimensional semi-infinite solid model is used to calculate temperature variation in ground.
