استنباط مؤشر لقياس مدى نضج الإرساب الرياحي : دراسة تطبيقية لنباك السهل الساحلي جنوب غرب خليج العقبة باستخدام تقنيات الجيوماتكس

Abstract EN

This scientific paper aims to reach an indicator to measure the quality of Eolian sedimentation, this was done based on an applied study on the Nabak fields located in the southwest of the Gulf of Aqaba.

Nebak formations appears as one of the Eolian forms in the southwest of the Gulf of Aqaba, Where the Mountain block retreated to give way for the coastal plain to expand.

The quaternary deposits spread, for example the Alluvial sedimentary where a lot of Drainage system ended in this area, and many of valleys composed Alluvial fans in the coastal plain, in addition to marine sedimentary such as sabkha deposits.

The formation of Nebak in the region has been subject to many Physical controls such as geological formations, in addition to the climatic conditions where the area is located in a dry zone.

The study was based on field survey and morphometric measurement, in addition to the analysis of topographic maps at scale 1: 50000 and using remot sensing techniques through processing OLI satellite image that taken by LandSat 8.

Many sand samples were collected from several site and analyzed to identify their physical, chemical and mineral properties.

The results were submitted using statistical analysis to highlight whether there is a discrepancy in the environmental conditions controlling the emergence of the phenomenon or whether it was subject to one physical condition.

In order to arrive at a scientific indicator, the study relied on three main variables: the area occupied by the sandy formations, the diffusion axes, and finally the amounts of sandy sediments
