Abstract
This paper is an assessment of the suspended sediment yield in the Mellah Catchment of northern Algeria. We use discharge–sediment load relationships to explore the variability of water discharge and sediment load, and to investigate the impact of geomorphic factors disturbance on erosion and sedimentation. Suspended sediment load was analyzed in the Mellah Catchment (550 km²) which was controlled by a gauging station to measure discharge and sediment transport. The relations between daily mean sediment concentration and daily mean water discharge were analyzed to develop sediment rating curves. For storms with no water samples, a sediment rating curve was developed. The technique involves stratification of data into discharge-based classes, the mean of which are used to fit a rating curve according to single flow data and season to provide various rating relationships. The mean annual sediment yield during the 24 years of the study period was 562 T km−2 in the Mellah Catchment. This drainage basin had high rainfall and runoff, the erosion was high. The high sediment yield in the Mellah basin could be explained by a high percentage of sparse grassland and cultivation developed on shallow marly silty-clayey soils with steep slopes often exceeding 12%. Almost all suspended sediment loads are transported during storm events that mainly occur in the winter and spring heavy and medium downpours. The scarceness of these events leads to a very large interseasonal variability of the wadi sediment fluxes. The negative impacts of this enhanced sediment mobility are directly felt in the western part of the basin which shows many mass movements, bank and gully erosion because cultivated areas are often bared during autumnal brief flash floods and furrowed downslope during the winter season.
Abstract
ملخص يهدف هذا العمل إلى التقدير الكمي للحمولة الصلبة العالقة في الشبكة الهيدروغرافية الخاصة بالحوض المائي ( الملاح) المتواجد في المنطقة الشمالية الجزائرية. لبلوغ هذا الهدف تم إنشاء علاقات إرتباط بين متغيرين : تدفق الماء و وزن الحمولة الصلبة . إضافة إلى هذا تم التحقيق قي تأثير العوامل الجيومرفولوجية على الحث المائي و عملية الترسيب لقد اعتمد تحليل الحمولة الصلبة العالقة في الحوض المــائي المـلاح (550 كم2) على قياس المحطة المتواجدة في عين المكان. حيث تم تسجيل عبر الزمن معطيات التدفق و الحمولة الصلبة الموافقة.إن العلاقات بين المتوسط اليومي لتركيز الحمولة الصلبة و بين المتوسط اليومي للتدفق المائي حللت لتطوير المنحيات النسبية للحمولة الصلبة، أما في حالة العواصف فإن المنحنى النسبي للحمولة الصلبة طور بلا عينات مائية.المتوسط السنوي للحمولة الصلبة خلال 24 سنة من فترة الدراسة كان 562 طن/كلم2. هذا الحوض المائي يتميز بجريان سطحي للمياه مؤديا إلى تعرية عالية. الحمولة الصلبة مرتفعة في حوض الملاح و هذا راجع إلى النسبة العالية للمراعي الغير كثيفة و الأراضي الزراعية الموجودة على تربة مرلية – غربنية طينية مع انحدارات قوية غالبا ما تتجاوز 12%. معظم الحمولة الصلبة العالقة تنتقل خلال العواصف الشتوية و الربيعية المشبعة بالأمطار الكثيفة و المتوسطة. إن تغير شدة الأمطار يؤدي في تغير الحمولة الصلبة للواد. الآثار السلبية لتحرك الحمولة الصلبة تلاحظ مباشرة في الجزء الغربي من الحوض الذي يتميز بالتحركات الكثلية للتربة و تعرية أطراف الواد و الأراضي الزراعية و المنحدرات المحروثة خلال فصل الشتاء.
