Abstract

Discharge of sediments load as well as its physical and chemical characteristics of Koudiat
Errasfa Dam has been monitored for understanding the nature of the sediments quality its
development, its effect of water. Composited samples are acquired from different depths,
starting from the water surface down to 30 m depth and horizontally at distances from the dam.
Sediment load chemistry was monitored for (pH, Ece, Ca++,Mg++, Fe3+,Cl-) for the dam pool
and Oued Lardjem suspended load. The results showed that the Koudiat Errasfa water would
not adversely affect its quality for municipal or fishery use.
The physical studies which including organic content, load texture, grain-size analysis by
mechanical and hydrometer methods.
Discharge of water and sediment load for Oued Lardjem (the main supplier of water to
the dam) also including in this study during months of Mars, April and may, 1993. Specific
erosion and the volume of sediments depositing in the reservoir also had taken big interest that
to find the actual age of the dam.
