الخصائص المورفومترية والجيومترية لحوض فايدة

القسم: Article

الملخص






تهدف الدراسة الحالية إلى تحليل الخصائص الجيومترية والمورفومترية لحوض فايدة باستخدام التقنيات الجيومكانية (GIS) والنموذج الارتفاع الرقمي (DEM  تضمنت المنهجية اشتقاق المتغيرات المساحية، والشكلية، والتضاريسية، فضلاً عن خصائص الشبكة التصريفية لتقييم السلوك الهيدرولوجي للحوض.


وأظهرت النتائج أن حوض فايدة يمتلك مساحة بلغت (119.86 كم²) وشبكة تصريفية من المرتبة الخامسة، مع كثافة تصريفية عالية تعكس سيادة الصخور الصماء وانخفاض نفاذية التربة. كما سجل التحليل الشكلي معامل استطالة قدره (0.7) ومعامل استدارة (0.4)، مما يشير إلى ميل الحوض نحو الشكل المستطيل الذي يعمل على إطالة زمن التركيز المائي نسبياً. ومن الناحية التضاريسية، سجل الحوض قيم وعورة مرتفعة (39.17) ومرحلة شباب جيومورفولوجي واضحة، مما يعزز من طاقته الحركية في نقل الرواسب وتوليد السيول الوميضية. تخلص الدراسة إلى أن حوض فايدة، رغم خصائصه الشكلية التي تؤخر وصول المياه، إلا أن وعورته العالية وكثافة تصريفه تجعله ذا حساسية مرتفعة لعمليات التعرية المائية، مما يستوجب اتخاذ تدابير وقائية لإدارة مخاطر السيول في المنطقة
