KARAPINAR (KONYA) THE LAST THREE YEARS OF SİNKHOLES AND CHARACTERISTICS

Abstract: Karapinar is located in the southeast of Konya and is 110 km away. The number of sinkholes with different diameters and depths, which we can call the world wonder, increased by 300 every day. These natural structures, which are formed as a result of internal karstification near settlements or in the middle of the fields, continue to be a threat for the people of the region. In the last three years, Karapinar has started to occur at more frequent intervals in the KB and there has been a significant increase in the number. In 2017, there were 17, 7 of which were 8, 2019 and 7 of which were in 2019. Miocene-Pliocene, Pleistocene and Holocene aged rocks are in the study area. The lithological characteristics of the land, the drop in groundwater level, the current direction of the groundwater, the chemical composition of the rock and the volcanic rocks of the Pliocene Uzecek Mountain and the other volcanoes around Karapınar are solved by the groundwater enriched by the carbonic acid. In the last three years, the ponds were formed in Karapinar's KB, in the vicinity of Üzecek Mountain, in Eşeli Karakul, Güllükkuyu, Çakırca, Üçler kamışağıl, Sırnık, Kızılcakuyu and Küçükkuyu. The distance between the settlements is 7-37 m. The circle is shaped 3-60 m. in diameter and 3-50 m in depth between. The depth of the sinkholes can not reach the level of groundwater in the region is waterless only one water is water.. In February, March, April and May, in the period when precipitation was high, the soil forming the agricultural lands became saturated with water. In July August and September, the increase in the weight on the soil cover was caused by the decrease of ground water level. Excessive attraction of groundwater in the region and the existence of a plant pattern that requires water accelerate the formation of sinkhole.
