Gully Erosion Rate Assessment at the Choqazanbil Temple Using GIS Methods

Abstract

The Choqazanbil temple located at 60 km of south west of shush city in the south west of Iran. This temple with 3500 years archaism is one of the oldest historical titles in Iran. The temple position is close to the Sardarabad anticline with Neogene to Quaternary deposits. Many news about damaging of ancient buildings are reported most recently. This report shows that stream erosion can excavate the land of temple up to 2 m. The aim of this study is to determine the rate of erosion around the Choqazanbil temple using GIS methods. We select one of streams in the western templeside. Aerial Photos and satellite imagery from 1951 to 2014 was collected for use in GIS calculations. The results of this study shown that gully erosion rates take increased over time. The average rate is 18.2 m/y. In next years, this value of gully erosion can make irrecoverable damages to the Choqazanbil temple.
