Abstract

Background and Objectives: the use of morphotectonic indicators in the evaluation of tectonic activities is a useful and reliable tool. teaching these indicators, it provides the basis for identifying tectonic areas and helps us in planning as well as possible. Therefore, this research was conducted with the aim of teaching morphotectonic indicators to geography students using GIS and Google earth.Methods: parameters such as basin Asymmetry Factor (AF), basin shape (BS), Ratio of valley – floor with to valley height (Vf), hypsometric integral (Hi) were studied and calculated in three classes (Class 1) = active, class 2 = semi-active and class 3 = Quiet) were classified. After calculating the mentioned indices, the amount of tectonic activities in the basins was evaluated using Index Of relative active tectonic (Iat) Findings: After calculating the mentioned indices, the amount of tectonic activity in the basin was evaluated using Of Index relative active tectonic (Iat) , based on which the Sadkharv basin was evaluated as having a high tectonic activity. Conclusion: It can be said that the parameters used in this research show the sensitivity of these indicators against active tectonic movements, which can be reliable evidence to prove the existence of neotectonic movements.
