The Northeast of Pará is characterized by the Amazonian old settlements, where the slash and burn small farming and large pastures are predominant. Its landscape is dominated by secondary vegetation at a widely succession stage and very few mature forest remnant, which are generally situated along the rivers and streams. In this context, the present study was conducted in fourteen small catchments under different land use and four other small catchments in forested areas under low anthropic impact, with the objective of evaluating the fluvial hydrogeochemistry to support two mesobasins management in the studied region. It was detected that the chemical composition of the evaluated small stream waters is being affected by the agriculture pra...
