Abstract:

The studied zone is a part of the Mellegne’s (North-East of Algeria) under pound, this zone is characterised by itssemi-arid climate.The water bearing system is formed by the plio-quaternairy alluviums resting on a marley substratuim of ageEocene.The geostatiscitcs approach of the hydrodynamics parameters (Hydrolic load, transmisivity) allowed the studyof their spatial distrubution (casting) by the method of Krigeage by blocks and the identification of zones withwater-bearing potentialities.In this respect, the zone of Ain Chabro which, is situated in the South of the plain shows the best values of thetransmisivity......The use of a bidimensinnel model in the differences ended in the permanent regime allowed us to establish theglobal balence sheet (overall assessment) of the tablecloth and to refine the transmisivity field. These would varymore exactley between 10-4 to 10-2 m2/s.The method associating the probability appraoch of Krigeage to that determining the model has facilited thewedging of the model and clarified the inflitration value
