Drought is a natural disaster which can lead to human and economic losses. This phenomenon takes place under different climatical system. There is not a general agreement about the definition of drought, because it depends on different spcialists as they have been pointed to meteorological , hydrological and agriculturaldroughts in scientific references. Meteorological drought is experienced only when rainfall deviates appreciably below normal. Hydrological drought is referrd to a periodical shortage of water resources for different activities in a given time. Agricultural is caused by an inadequate availability of soil-water over a critical period and this condition also depends on plant species and soil types. This paper attempt to compare between meteorological and hydrological drought in neighboring two basin placed on north mountain slope Shirkoh Yazd. To get a precise result ,gibbse-maher method for meteorological drought determination,and Z score to determine hydrological drought is used. For this purpose, the rain data at 2 raingauge station for a period 26 year(Eslamiea) and 28 year (Fakhrabad)is collected and analyzed. Reasearch findings show that there is a major difference between two basins.the trend in hydrological drought at Fakhrabad was not confirmed while it is confirmed in Eslamiea. There is a difference between hydrological drought in two basins ,too,it means that they are topsyturvy . There was no strong,significant relationship between debi and rain amounts in Eslamiea basin but confirmed in Fakhrabad basin.

Keywords: Trend, METEOROLOGICAL DROUGHT, HYDROLOGICAL DROUGHT, YAZD
