In this study, the geomorphological characteristics of the Gökırmak Basin were analyzed using Geographic Information Systems (GIS) and morphometric analysis methods. The Gökırmak Basin is located between the Küre Mountains and the Ilgaz Mountains, which form the central part of the North Anatolian Mountains. Situated within a young and dynamic orogenic belt, the basin exhibits a heterogeneous geological structure. This heterogeneity has led to the development of diverse morphological features across the basin area. The observed morphological diversity of the basin was revealed through 19 derent GIS-based morphometric analysis techniques. For this research, hydrological analyses were conducted using a Digital Elevation Model (DEM) with a spatial resolution of 12.5 meters, and the basin boundaries were delineated accordingly. In addition, 1:500,000 scale geological maps obtained from the General Directorate of Mineral Research and Exploration (MTA) were digitized in a GIS environment, and a geological map of the Gökırmak Basin was produced. The morphometric analyses employed in this study allow for the quantitative measurement, classification, and interpretation of landforms. Within this framework, the morphometric characteristics of the Gökırmak Basin were examined under three main categories: linear, areal, and relief aspects. Based on the findings derived from 19 different morphometric parameters, the influences of tectonic activity, erosional processes, morphodynamic evolution, and lithological controls on the present relief of the Gökırmak Basin were evaluated and interpreted.
