INTRODUCTION The principle of climate change, as a problem, despite of its various angles being discovered worldwide is still discussed by researchers, engineers and managers of related sectors. The importance of climate change issue becomes greatly apparent when this discussion develops issues related to water resource management and flow classification into various sectors of drinking, industry, agriculture and the environment (Cacho et al., 2008). In all of the basins that on its main river, a reservoir dam was constructed, and human factors can thus influence on different parts, the prospect of changing the flow in the basin is a principle. Undoubtedly, the management of two drought and flood issues is one of the priorities of water industry managers, whose short-term and long-term forecasts for making any decision, with respect to the high political, economic and social feedback, are indispensable. Hence, study of climate change and determining its effect on increasing or decreasing the severity of the two phenomena mentioned, as well as basin, along with the explanation of the effect of human factors on the mentioned issues is important. Simultaneously, exploitation of almost all dams constructed on the basin has been increasing (Jalili et al., 2012; Shokoohi and Morovati, 2015). There reported, of course, other analysis that demonstrate the contribution of human factors on the abnormal situation created for the lake through the construction of reservoir dams 628
