                         the land use changes in the Piracicamirim and Cabras watersheds 
                         during a 33 year-old period. The second is to identify the 
                         relationship between physical, biotic and anthropic aspects of the 
                         drainage basins and the water quality in the channel. Aerial 
                         photographs for the years 1962 and 1995 (scale 1:25,000)were used 
                         for obtaining thematic maps. During period considered, it was 
                         verified that in the Piracicamirim catchment there occurred a 
                         growth three times the urban area and of twice of the forest area. 
                         In the Cabras catchment the inverse occured, with a growth of 
                         two-times the urban area and three times the forest area. In a 
                         preliminary analysis it was observed that the medium values of the 
                         chemical composition of the Piracicamirim catchment were larger 
                         than those of Cabras catchment. Using these maps and various 
                         biogeochemical parameters obtained from the streams, it will be 
                         possible to constitute a digital database that will increase the 
                         understanding of the key processes that occur in these streams.",
