Abstract

Tehran province experienced one of the severest drought status during 1998 to 2000. This drought can be assessed by drought indices. Drought indices are quantitative expression of this disaster that make its spatial and temporal evaluations possible. In this research work three indices including EDI, SPI and DI have been used to develop monthly drought maps for the aforementioned period, using the information of 43 meteorological stations and geographical information system (GIS). The results show that DI has very exaggerated responses to rainfall, especially to the summer rainfall. Also SPI is not responsive enough to rainfall deficiencies. Morover, it frequently detected normal situation for this period. But, EDI is able to response properly and shows good temporal and spatial consistency in drought detection.
