Geomorphology of the Area Between Kasrik George and Cizre

Abstract

The aim of this study, which covers the Tigris River and its tributaries (Kızılsu River) established in Cizre and its surroundings, in the province of Şırnak in the Southeastern Anatolia Region, it is to examine the valley evolution process, geomorphologicalfeatures, response to tectonic. This works the evolution process of the Kızılsu River, which settled in the region by crossing Kasrik George the aim of to the factors affecting the morphological structure of the region. This area is important in terms of covering a part of Tigris River valley, one of Turkey’s most important rivers and tectonism-fluvial system relationship. In this research around Kasrik George; the formation process of the George (antesedant split valley), the step structure sandrock terrace formed by effect of tectonism on morphology are discussed and tectonism-fluvial system relationship is studied. The area where the Cizre district center was established and its immediate surroundings draw attention with the terraces of the Tigris River. In this study area, the Tigris River formed S1 (100-125 m), S2 (50-70 m), S3 (10-30 m) and S4 (3-5 m) terraces. The upper (S1) level of these landforms is covered with basalt sand formed a structural lava plateau. In addition, different drainage networks formed by the Tigris River and its tributaries are also seen in the study area.
