Abstract: 

In the basins of some rivers, there is a good relationship between annual rainfall and hydrological drought, This is because of some factors like Karst , the height porosity of basins and heavy rainfall. In this research, We have considered the relationship between rainfall and hydrological drought: According to climatic drought, threshold (-0/5) ,the threshold of SPI (-0/3) Were calculated for hydrological drought.
After extraction, the tables of intensity, duration and abundance were designed for both climatic and hydraulic drought for the last 2100 years.
Considening these tables and curves, it was shown that climatic droghts have happened between 1-3 months but hydrological ones have happened between five and twelve months.
Finally, with determining the R-Sq (adj) in the changes of Zdebi grades, it was cleared that there is only a meaningful correlation between yearly rainfall and Zdebi grade and rain falling in Aban, Azar, Ordibehesht with Zgrade of %95 and %99 level. For other months , although there is a high correlation and in many cases p- Value is close to Zero, but it isn't meaningful for %95 and %99 level.
