Etude de l'envasement du barrage d'Ouled mellouk (w. Ain defla)

Abstract

This present memory to aim to study the silting up of the dam of Ouled Mellouk wilaya of Ain Defla. Sediment transport is a complex phenomenon. The quantity of sediment transported is very important, and it fills in the reservoirs. A simple method, based on average discharges, easy to implement, has been developed for quantification of the sediment yield. It is based on hydrometric data. We used hydrometric data instant flow and concentration in suspension elements to the right of the station Ouled Tahar Bir. The processing of these data was carried out by establishing the two ratios, the first of which being the suspended element / liquid flow ratio and the second the ratio of the liquid flow rate to the solid flow rate, the ratio being established by l Use of regressive power model. Among these two relations, the relation between liquid flow rate and solid flow rate was retained for the relatively significant coefficient of correlation that it gives After the analysis of solid transport, we found a vase in the order of 40.31 volume hm3 which is higher than that estimated by the bathymetric tricks; this is due to the measurement of solid transport protocol..
