Avaliação estatística dos dados de regionalização de vazões para a Bacia Hidrográfica do Rio Chopim

Abstract

The water resources availability has fundamental importance to obtain reliable fluviometric data, since the insufficiency of quantitative information, combined with the spatial and temporal inconsistency of the available data are limiting factors for the representation of water behavior. As wide as the river monitoring network is, there is hardly any capacity to cover all points of interest. Therefore, it is necessary to use methodologies for estimation in different sections, where there is no availability of recorded data. Thus, this work aimed to evaluate the maximum, average, minimum and permanence flows (Q90) estimated from the traditional regionalization method of flows for the Chopim river basin. The elaboration of this work took place in stages, starting from the definition of the problem and a bibliographic research to identify similar works. Thereafter, the variables were defined and data collected for further processing and analysis of the results. Therefore, it was observed that the potential model is the one that presents the best adjustment with the regionalized data; and for the average and permanence flows the drainage area variable has better representation, while for the maximum and minimum flows, the length of the main river is the satisfactory variable result.
