| Abstract | With over 27000 square kilometers, the Rio das Velhas watershed is one of the most important in the state of Minas Gerais - Brazil. It also hosts its capital city Belo Horizonte and greater area with over three million people. While punctual pollution sources can easily be located, diffuse pollution can be very difficult to evaluate. A Landsat-7 mosaic of five images was created to produce a land cover/land use map of the whole watershed. These data were combined with water quality data within a GIS to assess the influence of diffuse pollution in segments of the river corresponding to fixed water sampling points. |
