Flow trend and precipitation anomaly on flow regime of Darungar river

In this study, trends in the monthly, seasonal and annual river discharge and rainfall by use of nonparametric test such as Kendall, Mann-Kendall, sen,spearman and pearson parametric correlation in Dargaz Daroongar basin were studied. For this purpose, discharge data from hydrometric stations Mohammad Taqi Beyk,sang surakh and Golkhandan and precipitation data from Dargaz, Mohammad Taqi Beyk, sang surakh and shamkhal stations were used. The results showed that the seasonal and annual trends were decrised in stations Mohammad Taqi Beyk and golkhandan. Pearson parametric and non-parametric Spearman were used to illustrate the relation between rainfall and river flows in a region and a significant positive correlation between summer rainfall and river flows have been approved by both tests
