Özet

Karst depressions and relict valleys, formed as a result of the combination of karst and fluvial processes, are characteristic landforms of the Taurus karst region in Turkey. Development of these two landforms is interrelated, and the main aim of this study is to explain the role of paleovalley networks on morphometric properties of the depressions. For this purpose, in this study, spatial distribution of karst depressions and relict valleys, and morphometric properties of depressions are investigated on the Ermenek Plateau based on 1:25,000-scaled, topographic maps. About 10,000 karst depressions are mapped, 49.5 % and 50.5 % of them being located in and out of relict valleys, respectively. According to morphometric calculations, there are significant differences in dimensional properties of the two groups of depressions. Mean area, perimeter, short and long axes of relict valley depressions are 2.6, 1.6, 1.6 and 1.4 times larger, respectively, than plateau depressions. Relict valley depressions and plateau depressions are elliptical-and circular-shaped, respectively. Relict valley density has positive effect, while non-relict valley density has negative effect (limiting factor) on spatial distribution of depression density. © 2018, National Speleological Society Inc..
