جيومورفولوجية الياردانج على سطح الهضبة الجيرية بين وادي النيل ومنخفض الفرافرة

الملخص EN

Yardang landforms is one of the most prominent geomorphologic units in Egypt’s western desert.

these unique landforms were formed by paleo-water corrosive action, and later on had been reworked by aeolian factors.

the current research is focusing on Yardang formation above the surface of limestone plateau which lie between the Nile valley from the east and Farafra depression from the west.

the research describes and analyzes the morphological characteristics and morphometric dimensions of Yardang, in addition to reviewing the most important factors and geomorphological processes affecting Yardang’s origin and development.

this research also classifies the landforms under consideration into five morphological sub-units: elongated, typical, semi-circular, domed, and pyramidal.

the current research studies in details a group of geomorphologic factors and processes that are involving in the formation and development of Yardang landscape, including aeolian abrasive roles, both physical and chemical weathering, and dynamic processes of mass wasting.
