Delazian desert is located in the northern part of the Central Iranian Kavir (Plain Kavir) and south of the Delazian Village. This quay is located at the confluence of the Shoolab river of Semnan and Ginab river, which connect to each other after crossing Semnan plain in this area. Due to the existence of these two river rivers, the swampy land is abundantly visible in this quest. On the margins of the swamps are salt domes.
In the vast part of the Dalazian Desert, vegetation is very weak, mainly drought-tolerant and passionate plants.
