Investigating the role of duality in geomorphology using radar data in Bahadoran plain of Yazd

Many varied attitudes exist about how the changes occur in the land-surface from the time of William Davis’s research to the latest researchers in the history of geomorphologic philosophy and many different terms are used by scientists in order to observe their ideas related to geomorphic phenomena. The phenomenon of duality has been seen less in the geomorphology field. There exist some contradictory phenomena in nature, but further investigation can show their correlation clearly. Durability can be considered as a better dynamic entropy. In this research, radar interferometry technique has been used in Yazd-Bahadoran area and the amount of subsidence and uplifting has been investigated Through field and library studies and the results have been compared with the other researchers' studies, which is a new concept in the literature of geomorphology under geo-duality. The study results indicate that the main reason for the subsidence was not to cut down the level of groundwater, and in this regard the tectonic movements play a significant role. Also, the study shows a significant relationship between subsidence in the Bahadoran plain and the collapse in adjacent heights in terms of duality or dichotomy.
