The analysis of the causes of underground warming using numerical simulation

However, recently, an energy conservation method that uses thermal heat is gaining attention and there is a need to understand the thermal environment in more detail. This study measured the ground temperature of gauge wells in the center of Hadano City, Kanagawa. In general, thermal temperature remains constant all year round at a certain depth from the ground surface. But, actual measurement results showed that the closer to the ground surface, the annual temperature rose more. This is thought to be the result of the rising temperature in the city center having an effect on the underground as well. As such, this study, for the purpose of analyzing the causes of underground warming, calculated the underground temperature through numerical simulation and reviewed how changes in the landcover composition structure that forms the ground surface and the temperature rise from urbanization affect underground temperature.
