The spatial dynamics of the multiple uses of river basin of Tucunduba (Belém/PA) is evaluated to identify the relationship between the use and occupation of its territory and its water demands. The methodology employs the use of geotechnologies for the registration of spatialized information and definition of homogeneous zones with regard to socioeconomic and natural features that could indicate the interventions occurred in a period of 12 years in the basin. The results showed a percentage increase of the occupation of the basin unaccompanied by the maintenance of water systems, creating a picture of imbalance between demand and water availability, as well generating conflicts between water usage and the need for preservation of recharge areas. The results also indicated that the application of geotechnologies can be considered a basic component of the process of water and environmental planning, given the possibility of constructing scenarios that model the different interventions that the systems can suffer.
