Abstract

The danger of amplitude movements is considered as one of the hazards that has occurred in many areas in recent years. Identifying the areas exposed to amplitude movements and estimating its rate plays an important role in managing and controlling this phenomenon. Radar Interference technique is an efficient method in measuring ground surface displacement which makes it possible to monitor small movements of the earth surface continuously, with high accuracy and in a wide range. This technology has become very common in the study of natural disasters of the earth, including slope displacement, subsidence, earthquakes and volcanic activity. This technique compares the phase taken from two radar datasets at two different times and. Besides, creating an interrogram, it is able to measure changes on the earth surface over time. In the current study, the radar images of 2015 and 2020 have been applied in order to identify and measure landslides. SARSCAPE software has been used to process information. The land-use map of the study area was extracted using Landsat 8 image and Object-oriented Classification method. The findings reveal that radar images have a good potential to detect the instability of slopes and to calculate their displacement. During the study period, the maximum amount of material movement has been recorded as 21 cm, indicating the area is active in terms of amplitude movements. The overlap of the landslide map with the land use layer also confirms the maximum occurrence of landslides in the use of vegetation and rainfed agriculture.
