ANALYSIS OF MULTIDIMENSIONALITY OF HYDROGRAPHIC BASIN CONCEPTS

The hydrographic basin (HB) is a study object used for Geography and Environmental Sciences, therefore new definitions have been created, making this cell of spatial analysis and planning compatible with integrated studies. Thus, it is important to ascertain whether the concepts created have undergone appropriate adaptations and delimitations to describe the object that they define and apply to technoscientific studies. In this perspective, it is based on the hypothesis that the concepts of HB, hydrographic sub-basin and microbasin have been adapted, but they present naccuracies in their conceptual delimitations. Therefore, the objective was to identify and analyze the most cited concepts in literature, aiming to improve them. For this, bibliographical research was carried out in which the main concepts of HB, sub-basin and microbasin used today were identified and examined. Subsequently, particular characteristics of each category of a HB were sought to distinguish the definitions studied, as well as to propose requalifications. Therefore, it was verified that the concepts available in literature have undergone adaptations, but often reduce a HB and its hierarchical categories to its hydrological or spatial aspects. The hierarchical system of HB and the analyzed definitions present faults in the ordering and conceptual delimitations of its objects, so it was possible to propose improvements in the definitions studied.
