Groundwater and surface water resources are severely affected by the lack of rainfall. Several indices provided for evaluation of drought based on meteorological and hydrological variables. In this study condition of meteorological and hydrological drought evaluated by SPI, SPEI, SDI and GRI. The correlation of indices was evaluated at different time scales. Base on the results SPEI has higher correlation than SPI with SDI at 9 and 12 months time scales and in the same month and one month later. Also SPEI has highest correlation with GRI at 24 and 48 months time scale that shows the impact of meteorological drought on groundwater level after two years and more. Knowledge of interval time between of meteorological drought as the main factor of drought would help to manager and planner for management practices in order to cope with drought due to lack of surface and ground water resources.
