ABSTRACT: In this paper, we proposed a method for mapping the suitability of land
for intensive anthropogenic use in the Maranhao River Basin, in the state of
Goiás, Brazil. We analyzed existing 1:250,000 maps of the local geology,
drainage system topography and geomorphological features. We generated new
information based on our analysis, including a compilation of basic
morphometric data and a map of the slopes in the basin, which we used to
construct the geomorphological suitability map of the watershed. Our results
indicate that 40% of the study area can support intensive anthropogenic use;
the remaining 60% of the basin area is categorized as “fragile” regarding the expansion
of intensive land use.
