RESUMO

The relative or complete lack of water has been directing various actions in order to solve this problem. The national water resources politic (Law 9.433/97) with its five instruments for water resources planning and management can be considered the main action. Among these instruments, it is found the information system that has as purpose to collect, store and turn it into available data to the rational management. In this scope and in order to give some contributions to the improvement of these systems, this Ph.D. thesis is presented. The main topic deals with the decision support system (DSS) implementation based on oriented object – OO, a kind of programming which tries to represent systems through classes very closely to the reality. This DSS, called ARENA (análise de recursos naturais, in Portuguese), is made up of a geographic information system (GIS), two models (a groundwater model and a distributed rainfall-runoff model), a georeferenced database and graphic user interfaces (GUI). The way the models were built, based on OO concepts and its integration to GIS geographic data, is presented as contribution. In the ARENA, the GIS is not only used in the pre and post processing steps, but also in the simulation. The ARENA applications were carried out for two examples, a watershed (surface water simulation) and a hypothetic system (groundwater simulation), both presented in the end of this study. The way this DSS was built induces to the development of other models without modifications in the existing packages, so that the development of new applications becomes easy because the use of existing packages that made this DSS up
