چکیده:

Long-term climate data of thirty stations in Sari County were analyzed in combination with information from local stations. For investigated drought indices include Standardized Precipitation Index (SPI), China Z-Index (CZI) and Z-Score Index (ZSI) to compare their resultant with water table variations. In this study we used the DIP (Drought Index Package) software for investigating drought indices. The precipitation records were used from January 1985 to December 2005. We compared drought value with water table variation to find best index for investigate and predict water table variation.
