Investigation of Konya Meteorological Snow Cover Depth Trend Using Mann Kendall and Innovative Sen Methods

This study investigates the snow cover depths trend in Konya province according to different approaches. For this purpose, trend analysis was carried out using the annual maximum snow cover depths data of 5 different stations in Konya. Trend data analysis at the stations was performed according to the Mann-Kendall and Innovative Sen Methods. In addition, the slope of the trend was found with Sen's Slope Estimator Test. According to the Mann-Kendall method, an increasing trend was observed in the annual maximum snow cover depth recorded in Beyşehir, but no trend was observed in other stations. According to the innovative Sen method, an increasing trend was observed in Konya Airport, Beyşehir, and Cihanbeyli stations, and a decreasing trend was observed in Akşehir and Ereğli. Trends obtained with different approaches reveal that the available TS EN 1991-1-3 standard, which determines snow loads, needs to be re-evaluated for Konya Airport, Beyşehir, and Cihanbeyli.
