Tourism plays an important role on development of economy especially in developing countries. The proposed study of this paper studies the impact of tourism on developing economic factors such as average income, real estate prices, etc. We have distributed 110 questionnaires among different people who are involved in various positions in the regions and analyzed the data. The survey is looking for the impact of tourism industry in terms of economical and social factors for one of the oldest villages in Iran named Maymand. The results indicate that there is a strong positive relationship, 0.873, between developing economy and tourism. In other word, developing tourism industry will help create more jobs, increase land prices, increase people & apos; s income and flourish environment. There is also a positive correlation, 0.854, between social development and tourism industry. This means we could expect a better health care system as well as medical treatment facilities, which helps prevent immigration to big cities.

Earth subsidence has been one of the important issues jeopardizing environment and there are many studies, which blame shortage of underground water resources for having uplift and subsidence. However, many argue such conclusion and believe that earth subsidence has been studied in the past without considering the changes in the hill over a long period. In this study, we use SAR interferometry study to investigate earth subsidence in dessert areas of Esfahan, Yazd and Ardakan, located in central part of Iran. The results indicate that there are more important issues affecting subsidence such as the uplift in the hills located the desert area. The results of the survey based on SAR interferometry reveals that subsidence occurs with the uplift in the adjacent hills, simultaneously called Soft isostasy in geomorphology. In other words, the subsidence is more associated with the movement of the surface of the desert to reach equilibrium than shortage of underground water resources. There is an equilibrium line between the uplift and subsidence where is changes of the surface tends to zero.

Tectonic geomorphology can be explained as the study of landforms produced by tectonic processes, or the application of geomorphic principles to the suggestion of tectonic problems. Tigrani & apos; s watershed is located in north part of hillside. Nayband Fault sub branch pass from the east of zone and kuhbanan fault from the north of zone supplies an appropriate theme for survey tectonic activities. For access to this aim geomorphic indexes contain Stream Length Gradient, Drainage Basin Shape Ratio, Ratio of Valley-floor with to Valley Height, Topographic Symmetry, Mountain Front Sinuosity and Asymmetry Factor with use of topographic maps, DEM, Arc GIS and Global mapper softwares have gained. The results of research which calculated with Iat index show west sub basin have medium tectonic activity (Iat=2), and east sub basin have high tectonic activity(Iat=1.5). Overall the results show that assessment of tectonic activities in Tigrani watershed this basin is active because of tectonic movements.
