ZAMAN, İKLİM VE AKARSU GELİŞİMİ

Abstract

In the long term (glacial/interglacial sequences), river development follows general climatic evolution. However, at the scale of one cold-warm cycle, it appears that the geomorphological effect of river activity is best expressed at times of climatic change. Such periods of pronounced fluvial action last only a short time. In more detail, the internal evolution in a drainage basin after a climatic event results in a delayed response of the morphology and sedimentation pattern. Finally, on the shortest timescale local thresholds may play a decisive role in the reactions of river systems. It is concluded that the relation between fluvial development and climate is not a simple one, but is fundamentally dependant on the timescale
