Abordagem geoestatística e de cluster para a análise do consumo residencial de água potável em Uberlândia-MG.

Abstract

Water is a natural resource responsible for the origin of life and your support on our Earth planet. It’s fundamental considered for the economic activities exercise such as agriculture and industry, also doing crucial importance of population life quality, especially, in what it mentions to water supply and the sewer treatment and collection, which has strong impact over the public health. So for a better control of this resource, is necessary a bigger spatial understanding and temporal of consuming. In this way, the objective of this article was study spatial behavior of the daily middle consumption of potable water in Uberlândia- MG city, along the months, for the 2015 year and also group the city's neighborhoods according to the similarity of consuming throughout the year. The spatial dependence analysis was made through semivariogram, which were used in the interpolation by kriging and consumption mapping of residential water. The cluster analysis was done by the multivariate cluster analysis technique. The results allowed to conclude that the variable studied, shows spatial dependence; the model which fits better to the data belongs to Gaussiana family, with an average level of dependence the cluster analysis indicated the formation of three different groups of neighborhoods for residential water consuming in relation of spatial distribution, it is observed predominance of bigger residential water consuming in the central area of the representative figure from the study area. The applied statistical techniques presented satisfactory results as to the description of the water consuming behavior in the Uberlândia-MG city.
