الملخص
اعتمدت الكثير من الدراسات المهتمة بتحرك المواد ومدى خطورتها على السكان وما لها أثار جانبية على النشاط السكاني والمستقرات البشرية التي تقع بالقرب من مصبات الوديان .
انطلقت الدراسة من تحليل العوامل المشكلة للمظهر الارض والتي تضمن مراجعة التاريخ الجيولوجي للمنطقة والحركات الارضية التي ساعدت على تكوين الشقوق والفواصل وصولاً الى الصدوع ,واثر المناخ القديم وانعكاساته على تشكيل المظهر الارضي اضافة الى سمات المناخ الحالي , اضاف على ذلك دراسة الخصائص الانحدارية والغطاء النباتي.
اشملت الدراسة على تحليل المؤشرات الديناميكية فقد تباينت حركة المواد من مكان الى اخر وتعود هذه الحركة في نشاطها الى العمليات المورفومناخية فقد امتازت المنطقة في مناخها الجاف وشبة الجاف الى تسريع العمليات الجيومورفولوجية (التعرية التجوية) فقد تبين من نموذج EPM ان التعرية السائدة في المنطقة بين المتوسطة والشديدة وحم الرواسب 5000-20000م3/كم2/سنة وهذه تعرية قوية جدا.
