| The main subject of the present work was to carry out a hydrochemistry comparative study between two river basins in São Paulo State: the Jacaré-Guaçu Basin (21°37'-22°22'S and 47°43'-48°57'W) and the Jaú Basin (22°09'-22°28'S and 48°16'-48°47'W). Nine sampling points in the Jacaré-Guaçu River and eight in the Jaú River were established. The water sampling was performed once each two months from March/95 to September/95. The following variables were analyzed: temperature (°C), pH, conductivity (muScm--1), dissolved oxygen (mg/L) and ionic water composition. Comparatively the Jaú River showed higher spatial variability, less oxygenated water and higher mineralization, due to high pedological and geological substrate richness, point sources existence and... |
