| The planet's climate has lost its balance in recent decades, so the issue of climate change has attracted much attention In the study of climate change, long-term statistics can show changes to a large extent. The purpose of this study was to investigate the statistical trend of monthly and annual series, flood discharge of Kashafrood river basin . Therefore, the statistical data of the last 65 years related to the monthly and annual series of the station were examined. Mann-Kendall test was used to check whether it was random or non-random, for the trend, type and time of change, which was observed in 5 months of the year increasing trend and in 7 months of sudden jump. Linear regression method was used for correlation of dependent and independent variables, which in most months, moderate or weak correlation was observed. Mann-Whitney and Kruskal-Wallis tests were used to evaluate the significance of jump points, which were significant in most months except November and June. | ||
