In this paper morphogenic method has been used as a base for defining and classification of geomorphologial deserts of Tehran province. For this purpose by using geological and topographical maps and combination of their data the geomorphological features individual for desert such as pedimonts, flood plains, nabkhas, salt deserts and salty flats, badlands, salty dome and salty massens and etc..., have been identified. Then by using ETM satellite images, feature boundary has been improved and the features identified and added to it. Finally recognized boundaries have been introduced as deserts boundary of Tehran province.
