Study area is in boundary province of Osmaniye at the sub region where it is Adana Part of Mediterranean Region. It has very difference topography because it is very young and active in terms of tectonic. Study area occurs a lot of geomorphologic units. Tectonism is the most importance factor to form. Furthermore, fluvial processes and karstification are secondary factors to take on shaping. Main geomorphologic units on the Düziçi plain which is nearly 90 km2 and near surrounding are Mountain-hills area, plateaus, valleys, brings alluvial fans and karstic forms which are small scale. Düziçi plain is elevation between 250 and 450 meters (average 350m.). Alluvial fans are between 300-400 meters in the east part of plain and mountainous-hilly areas are especially between 400-2246 meters in the part of east. Very small hills which are pressed down and volcanic cone are between 200-700 meters except for east other sides near the plain. Study area shaping had started from Miosen after that time tectonic activities had continued so, plain area has collapsed but mountainously area has increased since Miosen and along Pliosen-Quaternary. In the study area volcanic activity especially basalt flow and deposition in the lake had continued during the Plio-Quaternary and Quaternary era. In this way, Düziçi plain which is between 250-400 meters and its near surrounding have occurred and shaping which is especially erosion-deposition have been continued by rivers-weather present days (Holocene).
