Orta Sakarya Vadisi Akarsu Seki Sistemlerinin Morfometrik ve Sedimantolojik Özellikleri (İnhisar-Gemiciköy Arası, Bilecik)

Sakarya River, which is the largest river in northwest Anatolia, drains waters from a large area known as Middle Plateau. The most striking geomorphological features of and its tributaries this area, are joining gorges connect basins terrace systems together. This study aims to reveal morphometric sedimentological between Inhisar, Gemiciköy settlements. has settled region Upper Pliocene, formed that can be monitored several steps throughout valley. They under control climatic changes during Quaternary, sea level Black Sea, cyclical regional/local tectonic movements. Multiple terraces determined including following. Starting valley floor two (+19 m +11 height) around Gemiciköy, three (+36 m, +24 +12 Hamitabat village, four (+52 +34 +18 +10 Yakacık village. These formations, distributed irregularly along mostly semi-rounded gravel at high elevations, lower formations made small floodplain sediments.
