dc.descriptionThe high salinization in some reservoirs of the Comas river basin (Bahia-Brazil) has been erroneously attributed only to concentration by evaporation. However, recent studies of this basin have shown that in period of intense rainfalls, occur an increase of the saline concentration in the flowing rivers of the reservoirs. The application of statistical methods (cluster and principal components analysis) have shown that this fact can be attributed to the discharge of saline waters from the small reservoirs of every drained area, provoked by inundation, is also an important factor in the salinization process. Thus the study of the geochemical variables: Na+, K+, Ca2+, Mg2+, Cl-, SO42- and CO32-, showed one group formed by Na+ and Cl-, attributed to the discharge of saline water provoked by inundation from a small reservoir, and a second group constituted by Ca2+, Mg2+, K+ and SO42-, due to an increase provoked by the evaporation in the salinization process.
