Study of solid transport in Oued Ebda catchment (Algeria).

This work is a study of solid transportation and volumes of rising water an d base water at different scales in the Oued Ebda catchment (Ebda's river - North of Algeria). Indeed the National Dams Agency plans to build a dam at the level of this s ide basin. By the present work it was demonstrated the great effect of eros ion on Oued Ebda catchment (1875 t/km(2)/an) and the alluviation danger on the future dam. This work has also allowed to give some requirements to str uggle against erosion phenomenon and to protect the future dam against allu viation.
