It is known that water erosion and their suspended sediments transport, generally in the Maghreb region and particularly in Algeria, record very high values; knowledge of these sediments is a very important step in planning erosion control measures. In this study, we modeled and quantified suspended sediment in the Ressoul wadi, Seybouse basin in northeastern Algeria. The study was carried out at different time scales, during a period of 32 years from 1968/69 to 1999/2000 by establishing regressions between the measured sediment concentration and the water discharge at the watershed outlet. The results obtained by the proposed method indicate that the use of two regressions based on means of discharge classes technique reveals very good estimation of the suspended sediment load in the Ressoul wadi, with an error of 3.04% and a specific average degradation transported to the downstream of the watershed of 316.45 t/km²/year in the period of 32 years.

估计阿尔及利亚东北部不同时间尺度的悬浮泥沙浓度

众所周知，一般在马格里布地区，特别是在阿尔及利亚，水蚀及其悬浮物的迁移记录都很高。了解这些沉积物是规划侵蚀控制措施中非常重要的一步。在这项研究中，我们对阿尔及利亚东北部塞布兹盆地Ressoul旱谷的悬浮泥沙进行了建模和量化。该研究是在1968/69年至1999/2000年的32年期间，在不同的时间尺度上进行的，方法是建立测得的沉积物浓度与集水区出口的排水量之间的回归关系。通过提出的方法获得的结果表明，使用基于排放分类技术的两次回归可以很好地估算Ressoul旱谷中的悬浮泥沙负荷，误差为3。² /年（32年内）。
