| description | Spatial and temporal variability of precipitation increases with the effect of climate change. In this study, the Seyhan Basin has been determined as the study area. It is aimed to examine the spatiotemporal variability of precipitation and extreme precipitation indices in the Seyhan Basin. For this purpose, the period 1970–2019 was divided into three periods with the change point detection methods (Pettitt, Buishand rank and standard normal homogeneity test). Trends were examined by applying modified Mann–Kendall and Spearman's rho tests to precipitation and extreme indices for all periods and sub-periods. Then, temporal and spatial analyses of extreme indices were performed. According to the results obtained, there is no precipitation homogeneity throughout the basin. While the threat of drought comes to the fore with the decrease in rainy days and precipitation in the north, the risk of flooding is effective with the increase in precipitation intensity in the south.
HIGHLIGHTS
The spatiotemporal variability of precipitation and extreme precipitation indices in the Seyhan Basin was investigated.;
The change dates with change point detection methods were determined at the basin scale.;
The precipitation and extreme precipitation indices were analyzed with the modified Mann–Kendall and Spearman’s rho trend tests.;
The results of analysis were mapped and interpreted.; |
