The River Buyuk Menderes (RBM) with the 615 km course and 24,000 km(2) drainage area is the longest stream of not only Anatolia but also whole eastern Mediterranean region, which discharges into the Aegean Sea. It is also one of the driven elements on Quaternary morphology of western Anatolia. Upper course of the RBM places in the Baklan-Dinar Graben (BDG) while middle and lower courses are in Denizli Graben (DG) and Buyuk Menderes Graben (BMG) respectively. It has a meandering channel along the longitudinal profile except for some short discontinuities. In fact, the term "meandering" channel in earth sciences was originated from "Maiandros flu" the antic name of the RMB. Bused on results obtained from the BM delta (delta complex), the life story of the BMR has been in the last 250,000 years correspond to late Pleistocene. However, field geology and core studies indicated that the old RBM was a short, limited stream at the BMG till last Glacial Stage. During that time middle and upper course were separate drainage basins containing two lakes called Saraykoy Lake and Baklan Lake respectively. The Kufi stream and the Dinar stream have been discharging into the Baklan lake during the Lute Pleistocene, while the Banaz into the Saraykoy Lake producing a delta represented by the modern open-sand pits of Yenikoy. Lakes have been emptied by capture or back erosion and then large RBM could form in early Holocene. This capture increased significantly drainage area, water and sediment capacity of the new river, subsequently the uppermost part of the RBM delta complex occurred rapidly.
