استعمال نظم المعلومات الجغرافية في دراسة التعرية المائية المحتملة و تصنيف الأوساط بالأطلس الكبير الأوسط : حالة منخفض آيت أعتاب-المغرب

الملخص EN

This study that adopts ZERMOS methodology.

We will examine how GIS is used to deal with water erosion and the classification of areas in order to determine the factors that control the dynamics of erosion.

As well as studying the correlations between these factors, so as to reach the classification of areas and the degree of erosion.

In this respect, the study concluded that AIT-ATTAB Field is a very fertile case and ground to cope with water erosion in all its forms.

Furthermore, the morphodynamic activity in this field is linked to the combination of many natural factors such as: strong slopes, fragile rock dominance, low surface formation, Soil erosion and migration.In addition to that, The study also found that the scope of strong erosion is 28.31% (5%),the average erosion range is about 62.31% whereas the weak erosion range is 9.04%.

The study also recommends urgent intervention in a comprehensive and integrated approach to reduce erosion and its negative consequences over the field and as well as over the society.
