Özet

The purpose of the study is to illuminate the alluvial morphological evolution with respect to changing Geographical surroundings and environmental effects through the historical progression in the Torbali Plain. For that reason, first of all, data from drills in the region were collected, the alluvial materials obtained from the drill-bore holes have been analysed and then micro and macro biologic remains, and fossils were used as good indicators reflecting different environments. As a result of the investigations, from the pre-Holocene base to the present plain surface three different alluvial units were determined. These units have different habitats and reflect different geographical environments. These three units in the northern part of the Torbali Plain from the base to the surface are as follows: Pre-Holocene basement deposits, lacustrine-swamp fills and Fetrek stream flood fillings. Contrary to these layers, the units in the southern part of the plain from bottom to surface are as follows; Pre-Holocene fillings, marsh, lacustrine-shallow marine sediments, and Kucuk Menderes river flood filling sediments. From these findings, it is estimated that ancient settlements such as Metropolis was set up at the edge of the plain or on the slopes of the mountains because of the negative environmental effects of lakes and swampy fields in the flood plain. By the changing of the environmental conditions in the region, the findings implicated that new settlements started to develop towards the central parts of the Torbali Plain.
