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.

Numerical study on thermal regimes beneath canal in permafrost zones with different geological conditions

open access: yesShuili Shuiyun Gongcheng Xuebao, 2022
In permafrost regions, construction and operation of hydraulic projects will exert considerable thermal impact on underlying permafrost, and its degree will be different at locations with different permafrost geological conditions.

Shallow ground temperatures

open access: yes, 2000
The temperature in the ground changes according to daily or longer temperature cycles in the air. The amount of ground temperature change also diminishes rapidly with depth. Temperatures to a depth of 20 m, the approximate depth to which the yearly temperature cycle penetrates, are presented for various environments in the Mackenzie valley.

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.

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
