Determination of surface deformations in Bolvadin fault with precision leveling method and investigation of the relationship with underground waters

In this study, the amount of aseismic surface deformation occurring in Bolvadin district center in the last 10 years was determined by leveling method. For this purpose, the Bolvadin district center has a leveling network consisting of 9 profiles perpendicular to the surface deformations. 12 campaign leveling measurements were made between in 2016-2018. As a result of the measurements made, the deformations reaching to the 2 years 100 mm in the region were calculated. Subsequently, data were collected from DSI water wells in the region showing groundwater levels. It was determined that underground water levels decreased 5 meters in 24 months. Kendal, Sperman and Pearson correlation methods were used to investigate the correlation between groundwater levels and deformations. According to the results, there was a correlation between surface deformations and decrease in ground water levels except for wells 4 and 5.
