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.

Sciences de la terreTags : Jurassique plateforme plis algérie orientale jurassic shelf fold east Algeria عصر الجوراسي المسطح الطيات الجزائر الشرقية Index. décimale : 550 Sciences de la terre Résumé : The studied area is constituting a hinge zone, at the convergence of the Alpine's range internal zones of Eastern Algeria and the Atlasic domain. It is centred on the South-Setifian platform, which is the western extension of the Constantinois neritic pier. Stratigraphically, the detailed lithostratigraphic analysis of the outcrops allowed the revising of the bio-lithostratigraphic schema of the meridional south-setifian facies and northern aurésian facies. In this context, some formations and units have been adopted and biostratigraphically repositioned, others have been identified for the first time. Sedimentologically, the microfacies’ analysis of the sedimentary series has revealed that:
- Jurassic facies characterize a platform medium that is progressively evolving according to tectonics, subsidence and eustatism whose joint actions are influencing the carbonate production.
- Cretaceous facies refer to two types of platform: a detrital platform and a carbonate platform, the influence of which is controlled by the sedimentary dynamics and the dominant energetic action.
- The Neogenic facies have a continental aspect with, in some places, a Molechfor biofacies and / or a Rhodalgal biofacies, which are translate as a filling of paleovalleys.
Structurally, the structural style of the north aurésian autochthonous Mountains is characterized by a succession of folds oriented E-W to NE-SW, affected by numerous faults which, most often, bring out the limestone massifs in horst. Among these brittle accidents, NWSE dextral strik-slip faults, which limit the shear zones, are the most numerous and most apparent. In the shear zone that joins the Messaouda massif to the Mestaoua massif, the dextral recesses, arranged in echelon, induce a virgation, also dexterally of the fold axes. The overlapping series, located in the south of the Messaouda Massif and SW of the Mestaoua Massif, represent the inverse flanks of anticlinal structures. All these structural dispositifs reveal fold-fault structures. However, a ramp and landing structure, supported by the surface geometry, can be envisaged. In this case, the shortening is fully or partially accommodated by folding. Thus, the present structures oblige not to envisage a tangential tectogenesis of regional amplitude.
