    Abstract: Old words “People go upwards, Water flow downwards”. The new mathematic physics model of underground water circulate was built. This model was based on Newton attract force equation deduction.

    Abstract: This investigation represents temporal and spatial analysis of drought events over Iran for a 42 - year period (1963 - 2005). At first, the severity of drought occurrences over Iran has been identified using SPI (Standardized Precipitation Index) at various time scales (i.e., 3, 9, and 12 - month) for 50 synoptic stations. Then the spatial distribu... Show More
