Abstract

The study area is in the north of Chelgard city, the central part of Koohrang city in the west of Chaharmahal and Bakhtiari province. The purpose of this study is to evaluate the tectonic evidence related to the activity of Koohrang fault in Zardkooh heights. In this study using indicators Hypsometric integral morphometry (Hi), Drainage basin asymmetry (Af), River gradient (SL), The shape of the basin (BS) is calculated. In order to determine the relative tectonic morphological activity in the study area, The relative active tectonics index (IAT) has been calculated. The map shows the resulting zoning index (IAT) New tectonic activities have not been the same everywhere in the region Basins with different New construction activity are scattered in the area In general Koohrang fault and its sub-faults are active in some sections and basins, according to the obtained results, the area has moderate to low tectonic morphological activity.
