Abstract :
Many varied attitudes exist about how the changes occur in the land-surface from thetime of William Davis’s research to the latest researchers in the history ofgeomorphologic philosophy and many different terms are used by scientists in order toobserve their ideas related to geomorphic phenomena. The phenomenon of duality hasbeen seen less in the geomorphology field. There exist some contradictory phenomenain nature, but further investigation can show their correlation clearly. Durability can beconsidered as a better dynamic entropy. In this research, radar interferometrytechnique has been used in Yazd-Bahadoran area and the amount of subsidence anduplifting has been investigated Through field and library studies and the results havebeen compared with the other researchers' studies, which is a new concept in theliterature of geomorphology under geo-duality. The study results indicate that the mainreason for the subsidence was not to cut down the level of groundwater, and in thisregard the tectonic movements play a significant role. Also, the study shows asignificant relationship between subsidence in the Bahadoran plain and the collapse inadjacent heights in terms of duality or dichotomy.
