An Overview of the Geomorphological Characteristics of the Pergamon Micro-Region (Bakırçay and Madra River Catchments, Aegean Region, West Turkey)

Current landforms are the basis for understanding past geomorphodynamics and human activities. Based on multiple materials methods, including geomorphometric analyses of a digital elevation model visual interpretations satellite images, different landscape units Bakırçay Madra River catchments in environs ancient Pergamon described. The area was mainly shaped by tectonics that formed horst-and-graben structure; small Miocene horsts NE-trending subgrabens Kozak Yunt Dağı Mountains were separated NEE-trending Plio-Pleistocene Bergama Graben. asymmetry relief, drainage network, sediment accumulation between to north south lower plain characterize Micro-Region. regional relief characteristics, with wide flat basin plateau areas, suitable agriculture. Complemented its richness natural resources, Micro-Region became preferred settlement area, evidence impact since Hellenistic–Roman period at latest. As consequence activities, several engineering measures implemented simultaneously parallel change morphodynamics.
