Abstract

Although, many studies have been reported on meteorological drought monitoring and analysis, similar studies on groundwater drought in regions with high abstractions are lacking. In this paper, the effects of groundwater extraction from aquifer were investigated and groundwater drought analysis was performed using the naturalized groundwater level time series in Qazvin plain. For this purpose, MODFLOW-ANN coupled model were used to obtain the time series of naturalized groundwater level over a 50-and a 3-year period. Then, the groundwater drought was monitored by means of the SGI and was compared with the SPI and SHDI indices. Also, drought characteristics were calculated during the 50 year period and the regions with higher Drought Hazard were determined. Results showed that abstraction caused severe negative trend in the groundwater level. Also the aquifer was in long duration dry condition in about 47% of the time. Groundwater level changes have a 9 months delay to changes in precipitation and surface flow rivers. Groundwater drought is more strongly correlated with hydrological drought than with meteorological drought. Also, Boeinzahra county has a higher and Qazvin and Alborz have a lower hazard than other regions.
