Bedload Estimation: Case of Wadi El-Hammam in the North-West of Algeria

In Algeria, only the transport of suspended sediment is measured, rate bedload in global solids estimated, approximately. Measures bed load field are very costly, due to flow disturbances. As a result, evaluations this type difficult carry out absence databases. article, we tried quantify mode at wadi El-Hammam using formula Meyer-Peter and Müller. Formula that seems best adapted physical characteristics conditions studied. The results obtained show calculated ratio between 0.6 28 % suspension. quantities transported annually large irregular as they vary from 2.3 32 Mg.km-2.year-1, characterising Mediterranean mountains semi-arid environments. A good correlation was found daily liquid flow, model Qs = aQb, can be easily used estimate Hacine hydrometric station, located output without data concerning phenomenon.
