| Changes in the amount and distribution of flow discharge are a remarkable manifestation of climate change. Reducing or increasing the amount of flow discharge affects many other climatic and environmental phenomena such as runoff, flood, humidity and also affect many human activities such as agriculture, economics ,the fight against soil erosion and so on. In this study, the trend of river flow discharge in the Urmia lake basin was investigated in two annual and monthly scales using modified non-parametric Mann-Kendall test (MMK) with complete removal of the self-correlation structure. To this end, 26 hydrometric stations were surveyed in the Urmia Lake basin during the statistical period of 1984-2013. Also, non-parametric Pettitt test was used to determine the time of change in flow trend. The results of the trend of the studied stations in the Urmia lake basin showed that the course of the changes in the flow discharge is decreasing in most months. On a yearly scale, at all stations, there was a trend of decreasing flow in the basin area. Also, the trend of flow discharge decline is more intense in both autumn and winter. The time of change in the decreasing trend of the flow discharge in the Urmia Lake basin was also taking place between 1994 and 1998. Also the results indicated that the decreasing trend of Urmia Lake water level data occurred one year after the decreasing trend in flow data. | ||
