TEKİRDAĞ İLİNDE COĞRAFİ BİLGİ SİSTEMLERİ VE ANALİTİK HİYERARŞİ SÜRECİ KULLANARAK HEYELAN DUYARLILIK ANALİZİ
USING GEOGRAPHIC INFORMATION SYSTEM AND ANALYTICAL HIERARCHY PROCESS IN LANDSLIDE SUSCEPTIBILITY ANALYSIS IN TEKIRDAĞ PROVINCE

Summary/Abstract: Being under the control of various factors, landslides are one of the important natural disasters in Turkey, as in the entire world. In recent years, susceptibility maps have started to be produced in order to minimize the effect of this disaster. Many methods have been developed and used for that. They have been designed based on Geographic Information Systems (GIS) in particular. In this way, all factors leading to the occurrence of landslides may be analyzed more systematically and practically. Intuitive approaches based on GIS have been employed in landslide susceptibility studies recently. The most preferred ones are the models involving the Analytic Hierarchy Process (AHP) method. The present study aimed at making the landslide susceptibility analysis of Tekirdağ province through the AHP method based on GIS techniques. The significance of the study is that it has been carried out within the borders of an administrative province where there are a high landslide occurrence potential and effect. In addition, it is considered that these kinds of studies are very important for site selection and relevant planning works in Turkey. Various kinds of materials obtained from different sources and the GIS based AHP method are employed in the present study. In the light of the research findings, it is understood that there is a medium landslide occurrence potential in Tekirdağ province. It is determined that more than half of the urban area (51.5 %) is under medium landslide hazard. Landslide hazard is mostly observed in mountainous and sloping lands. In conclusion, it is confirmed that the GIS based AHP method could be used for preparing landslide susceptibility maps in accordance with administrative borders. These kinds of maps could be used in site selection planning works.
