Trend analysis of lakes and sinkholes in the Konya Closed Basin, in Turkey

This study aims to investigate the trend of water-level changes in lakes (Lake Tuz and Lake Bey?ehir) sinkholes (Timra? K?zören) Konya Closed Basin located Turkey. Water-level these were investigated along with meteorological parameters (precipitation, temperature, evaporation) groundwater trends that indicate climate region. Several statistical tests can be used determine significance hydrological over time. These are divided into two categories: parametric nonparametric. In this study, nonparametric Innovate Sen test, Modified Mann–Kendall Linear test used. According analysis, water levels K?zören Timra? decreased time, while Bey?ehir increased. results supported by data level stations determined Thiessen polygons sub-basin boundaries.
