                         Amazonian catchment area to illustrate large scale deforestation 
                         effects on 'islands' of preserved areas, for the situations with 
                         and without climate changes. In addition, model sensitivity in 
                         response to different organic matter levels in the soil and stream 
                         waters as well as to different Al solubility constants was 
                         evaluated. The model output was strongly dependent on the chosen 
                         values of organic matter concentration and Al solubility constant. 
                         Application of the model to a 30 yr deforestation program revealed 
                         increases in streamwater ionic concentrations with or without 
                         climate change, although streamwater ionic concentrations were 
                         predicted to be higher as a consequence of climate change. On the 
                         centennial scale, streamwater ionic concentrations reach a new 
                         equilibrium, with concentrations higher than those prior to the 
                         surrounding deforestation. With the assumed increased cation 
                         deposition to the preserved forest areas, soil exchangeable cation 
                         concentrations increase with time and aluminum is released to 
                         solution. At the end of the simulated deforestation program, SO42- 
                         in the preserved areas began to be released to streamwater, 
                         inducing acidification. Application of the MAGIC model makes 
                         possible to estimate, for the rainforest environment, water 
                         quality changes as a function of different climate and land use 
                         changes.",
