The current study was carried out in the Cheliff watershed in Algeria, to assess the drought severity and analyze the significance of the spatiotemporal trend of annual rainfall during the period from 1914 to 2011. In this study, the rainfall series of eight stations were subject to standardized precipitation index (SPI) analysis, homogeneity tests, trend analysis and exponential smoothing in order to make a short time rainfall prediction. The results showed that the annual rainfall amount was highly dependent on latitude and elevation.
