Abstract

The Gaziköy–Saros
region is located in the western part of the North Anatolian Fault Zone (NAFZ),
Turkey, which is one of the major active strike-slip faults recognized in the
world. The morphological characteristics of this region
were shaped by the nature of the fault. By means of combination techniques of remotely sensed and
Digital Elevation Model (DEM) data a 3-D (three-dimensional) model can be
generated. Afterwards, the produced 3-D model of the study region can be effectively
used in examining the aforesaid features and various other associated analyses.
In this study,  the DEM data is obtained
by  digitizing 1/25,000 scaled maps and Landsat
5 TM data. A novel method is used to
define the region’s geomorphology through merged digital elevation model (DEM)
and remotely sensed data. The morphometric analyses of our study identified
five erosion surfaces and indicated that the active faults contributed to the
morphological development of the study area. Moreover, another hypothesis derived
from our study is that the formation of the elevated areas was caused by fault
compressional force components and formation’s linear features were produced by
the strike-slips.
