“…The water catchment area of Oued Allala belongs to the group of coastal basins of Algeria, a relatively narrow littoral zone between the mouth of the Chelif and the zaccar massif, thus forming a relatively homogeneous Geographical Unit [12]. It covers an area of 296.34 km2 and a perimeter of 94.36 km and with an average slope of 2.25 % and a main watercourse of 31.57 km that its average slope is 2.84% fig 1.…”

“…The data cover the period from 1982 to 2013 .The liquid discharge are obtained in two ways on the basis of the rating curve and by counting the water heights recorded by the liminigraph. The sediment concentration measurement consists of systematic collection of water samples using a flask with a capacity of 500 cl, more samples are taken during periods of high water, while in low flow or when the liquid discharge is constant during the day [13].the suspended solid discharge rate is given by the following formula :…”

In Algeria, the problems of erosion and sediment transport are critical, since they have the most dramatic consequences of the degradation of agricultural soils on the one hand and the siltation of the dam on the other .The sediment transport in the Algerian basins is very important especially during the periods of floods, It is in this sense that this study, which consists of estimating the sediment transport in suspension and determining the models of relation linking the liquid discharge and the sediment discharge in order to estimate the solid transport in the absence of suspended sediments concentration data at the Sidi Akkacha station at the outlet of the basin of Oued Allala which is subject to a high water erosion, it degrades from one year to the other under the effect of this phenomenon especially during the floods which drain high amounts of fine particles exceeding in general, the concentration of 150 g/l, the results obtained from the application of the models are very encouraging since the correlation between liquid and solid discharge exceeds 80 %.
