Abstract: 

Drought and water scarcity are two of the most important key terms in the water resources management. Drought as a large scale natural disaster is out of water resources managers control. On the contrary, water scarcity, which is the result of the wasteful and immethodical use of water resources, can be managed using precise and proper management decisions which will result in protection of water resources. Due to the fact that in most cases these two phenomena or disasters often occur simultaneously, it is tried in this research to use a simple conceptual water balance approach in the observational-modelling framework to discriminate the effects of drought and water scarcity on the basin runoff. This framework which is suggested by Van Loon and Van Lanen, (2013) allows a pure simulation of the hydrological parameters not taking into account the impacts of human activities in the Basin. This would validate a hydrological model for the period when the basin was not disturbed by the human activities and then by developing the model through years when the basin has been highly influenced by human activities and natural fluctuations, it can evaluate and determine the influence values of such effects. The results indicated that although in period of October 2000-September 2012 (water years of 1379-1380 to 1390-1391), the amount of monthly precipitation decreased by nearly 12% in compared to the long-term period of October 1972 to September 2000 (water years of 1351-1352 to 1378-1379), the ecosystem has nonetheless met the minimum environmental water requirements and slightly suffered from drought. The major cause of water shortage in the basin was accordingly the extensive human activities so that even in wet years a considerable decrease in discharge have been observed.
