ABSTRACT: The study areais located in the north Tehran, Iran.
Calculation of transverse topographic symmetry factor (T) is suitable for rapid
assessment of active tectonics. Therefore, transverse topographic symmetry
factors havebeencalculated for
the Darakeh stream. The study area is located in the Tehran Piedmont and
transverse topographic symmetry factoris
calculated for it. Based on values of this index, there is high relative
tectonic activity level. This condition can be related to existence of a blind
north-south striking fault which it may be buried by alluvium of the Darakeh
stream. Dendritic drainage pattern of Darakeh stream and the fact that the western
tributaries are longer than the eastern tributaries provide indirect evidence
of ground tilting toward the east. Also, based on our results, most part of the
study area have got high tectonic activity that it is compatible with its
tectonic setting on the Tehran in north Iran.
