The Effect Of Urban Heat Island On Groundwater Located In Shallow Aquifers Of Kütahya City Center And Shallow Geothermal Energy Potential Of The Region, Turkey, Ali Samet Öngen, Zeynel Abidin Ergüler
Bulletin of the Mineral Research and Exploration
As a result of urbanization, natural surfaces are replaced by artificial surfaces that trap heat such as buildings, pavements and asphalt, so residential areas have higher temperature values than rural areas. This effect, defined as the urban heat island, causes an increase not only in air temperature but also in the subsurface and groundwater. Groundwater temperature values were measured during one year in an area approximately 53 km2 consisting of different types of settlement areas to determine the urban heat island effect on the subsurface of Kütahya. As a result of the measurements, urban heat island maps were prepared. It …

Geological Characteristics Of The Boundary Between Bolkardağı - Bozkır Units And The Ulukışla Basin And The Structural Evolution Of The Region, Central Taurides, Turkey, Tolga Esi̇rtgen, Veysel Işik
Bulletin of the Mineral Research and Exploration
The character of the boundary between the tectonic units in the Central Taurides and the Ulukışla Basin is controversial. The contact has been accepted as discordant or tectonic contact by different researchers. The deformation data of the units in the study area provide important information about the Mesozoic - Cenozoic period geological developments of the region. Regional compression in NW - SE direction has caused the development of fold, foliation and reverse fault type structures in the units in the study area. Similar structural deformations are observed in the rock units defined in the Ulukışla Basin as well. In this …

Shorelines are important boundaries separating the erosional and the depositional areas. Determining the location of the shorelines in geological time sand how it changes by the time is one of the major problems of geology. The most accurate estimate of the location of the shoreline, which is a dynamic structure, in the period when it was exist is very important in palaeogeographic studies. The determination of coastal changes by the time provides valuable information on active tectonic sand climate, and the relationships between these two.
