During last three decades, Algeria is known for an immense and ambitious program in building of dams. Climatically, East Algeria is of the most abundant rainfall in the territory, where 25 dams are recently in operation, distributed through watersheds, with very contrasting physical characters. On the hydrotechnical plan, it’s characterized by the large variety in hydraulic properties specified from the perspective of their basins catchment, availability of lakes/reservoirs, and other auxiliary works. Data of water balance from the National Agency of Dams and Transfers (A.N.B.T) associates the follow-up and studies on the monthly and annual evolutions of entries, exits and deficits in the dams, as well as the knowledge of the hydrological behavior of the construction driven by the rainfall and other climatic fluctuations generally. Based on the analysis in ten dams with a hydrological observation over 23 years (from September 1990 to August 2013), a significant difference between the average interannual regulated volume (21.0 hm³) and theoretical regulated volume (37.7 hm³) shows an importance deficit in the water supply system which is strongly related to the frequency of wet and dry years. A chronological graphic method, with a statistical approach in data processing (type ""Bertin matrix""), is applied for three principal parameters (input, rainfall and storage rate). The result indicates a strong relationship between the parameters studied: a clear growth from the dry years from September 1990 until August 2002, and vice versa for wet years from 2003. These results are confirmed by the wavelet analysis: the dams storability are strongly influenced (from 66 % to 93 %) by a climatic variability and the left (from 7 to 34 %) is related to other factors such as the physiography of basin catchments. Results of the water balance show strong water losses by evaporation. The volume of water leaked, particularly on the karst sites (Foum El Gherza and Hammam Grouz), can reach to a significant peak specifically during the wet years 1990/91 and 2004/05. Otherwise, the phenomena of risings origins from excessive volumes evacuated from reservoirs or drainage of dams as details in the flood study for three dams Cheffia, Zardezas and Foum El Gherza. The quantification of sediment volumes in the dams (bathymetric campaigns 2004 and 2014) shows a reduction in storage capacity of the dams over time with a storage loss of 231 hm³ according to the survey in 2004, and 328 hm³ comparing to 2014. Finally, the analysis focuses on the inter-basin water transfer systems from large dams, and on the possibility of an interconnected management system to cooperate the basins in Eastern Algeria.Note de contenu : Annexes.

The hydro-sedimentary flow that characterizes the Soummam watershed is conditioned by morpho-structural and hydro-climatic frameworks and land use and cultural practices that allow fairly active water erosion in all its forms. The number and distribution of hydrometric stations that control the watershed is far from satisfactory (05 stations for an area of 9125 km2). Also, from 1985, the Soummam watershed the construction of four dams Lakhel (1985), Ain Zada (1986), Tilesdit (2004) and Tichy Haf (2007), which made the old network (1972/1985 series) of stations which are mostly obsolete. Thus, a second series of measures will be used by integrating the dams after they have been filled. The analysis and comparison of the two series allowed us to follow the evolution of the hydro-sedimentary flow before and after the hydraulic developments. The volume of solid input to the Sidi Aiche station (92% of the area of the Soummam watershed) is halved. The bathymetric data made it possible to verify the specific degradations obtained by the measurements of transport in suspension. However, these results are far from indicating the areas of contribution within the large Soummam watershed. The USLE model allows quantification and spatialization of erosion. It is a model developed from data on plots, but which has shown a certain flexibility which allows its application to watersheds. The average annual loss of soil, per unit of area, depends on several factors, namely: rain erosion, soil erodibility, plant cover, and topography and conservation practices. The annual intake obtained by this model does not reach 50% of the intake measured at the Sidi Aiche station. This contribution is only due to erosion in the water table. Thus, to improve the results and strengthen the applicability of the model to watersheds, we have added the contribution of two other forms of erosion: mass movements and gullying. Nonexistent forms on the experimental plots used by Wischmeier. The combination of data relating to each form and the modeling are carried out in a Geographic Information System (GIS) in order to obtain a map of the contribution areas in t / km2 / year. The model's land losses became equal to the sum of the contributions of the three forms of erosion and which is estimated at 90% of the measured annual contribution. We have successfully applied the same approach to sub-basins controlled by a hydrometric station. These encouraging results largely attenuate the contradictions resulting from the transition from the plot to the watershed. In addition, due to the hydraulic arrangements made in the Soummam watershed, the solid contribution to the mouth is halved. This situation is certainly at the origin of the increase in the speed of retreat of the coastline at Bejaia Bay.
