        Many varied attitudes exists about how the changes occur in the land-surface from the time William Davis’s researches 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 less seen 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, as well as through field and library studies, the amount of subsidence and uplifting has been investigated 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. Manuscript profile

        In general, from ancient times to the present, there are various methods for collecting location-based data, including astronomical observations, photogrammetry, mapping and remote sensing. Remote sensing is one of the data collection methods in which it has the least amount of direct contact with the objects and features being measured and unlike other methods in which human factors play a role in collecting and interpreting terrestrial data, in remote sensing method the task of collecting information will be the responsibility of the sensors. Due to the over-exploitation of natural resources, the landscape is constantly changing and monitoring these changes as well as updating maps is costly and time consuming, so many developed countries now have to prepare maps in Different levels use satellite data. The factors studied in this research include 1 preparation of land cover maps and land use of a part of Khuzestan lands. 2 Evaluation of bio-ecological potential in agricultural development of the study area by weighted overlap method. With regard to collecting information, studying the obtained maps and calculations, determining the criteria, final weights and classification of layers in determining the potential of the region for agricultural use, the amount of changes in agricultural areas between 2014 and 2016 was determined. According to calculations, it is about twelve percent, which according to the changes that have taken place are very significant and show the intensity of the changes in recent years. Loss of vegetation is a factor in increasing wind speed and destroying soil texture and structure. It is also a cause of dust, the result of which can be seen in recent years. Manuscript profile
