تحليل الاستجابة المائية ( CN ) لحوض التصريف (الخرازي) في مدينة الموصل
الملخص
يهدف البحث إلى تحليل الاستجابة المائية لأحواض منطقة الدراسة باستخدام نموذج (SCS-CN) وبيئة .(GIS) اعتمدت المنهجية على تقاطع بيانات استعمالات الأرض المشتقة من المرئية الفضائية (Sentinel) مع الأصناف الهيدرولوجية للتربة. أظهرت النتائج هيمنة الأراضي المشيدة بنسبة (59.06%)، وسيادة التربة ذات النفاذية الضعيفة (D) بنسبة (42.69%). سُجلت قيم مرتفعة لرقم المنحنى بلغت ذروتها عند (CN=92) بمساحة (29.77%)، مما أدى لانخفاض معامل التخزين (S) إلى (22.09 ملم) وتوليد حجم جريان بلغ (838,305 م³). تُثبت الدراسة الحساسية العالية للحوض تجاه السيول السريعة نتيجة التوسع العمراني وضعف النفاذية، مما يستوجب تبني استراتيجيات الحصاد المائي وإدارة المخاطر
