Résumé
The purpose of this study was to predict, analyze and evaluate the state of , Khuzestan Province droughts and its effects on surface waters, thereby recognizing drought management and providing appropriate solutions for coping with drought and dehydration, in order to reduce the damage caused by it. . In this research, using climatic data (precipitation) and using DIC software and 3 drought indicators (DI-SIAP-SPI) to analyze, evaluate and monitor the severity and frequency of droughts in Khuzestan province during a 30-year period (1981-2010) was studied at 3 stations in Ahvaz, Abadan, Dezful, Iran. Finally, using SPSS software for linking droughts and reducing precipitation with river discharge in the province . According to the results obtained in the studied areas, the number of droughts is more than that of the elderly and has been exacerbated in the final years (2007-2010). According to the trend diagram, precipitation in the province is decreasing and predicted. The same trend continues and droughts continue and SPSS software correlates between the changes in the Karun River and Ahwaz River rainfall, which is also reduced by decreasing the rainfall of the rivers, so we conclude that there is an increase in droughts (decreasing rainfall) And the Karun river flood is inversely correlated with the increase in droughts, Finds .
