Analysis of the relationship between the compactness of urban forms and the patterns of water supply in cities

Abstract

This article aims to analyze the relationship between the compactness of urban areas and the patterns of water supply in the area of ​​cities through the study of minimum flows for distribution networks. In this sense, we sought to statistically correlate geometric, demographic and water supply/distribution parameters in a city, through a case study in the urban area of ​​Uberlândia/MG, a typical medium-sized Brazilian city. Using the Google Earth Professional software, the geometric contours, perimeters and areas of all neighborhoods and geographic areas of the municipality were determined. In addition, through data provided by the municipal government, the total populations of each neighborhood were determined. Thus, the compactness index and the population density of the units in the urban area were determined. In addition, based on ABNT NBR 12211/1992, the average water consumption and minimum supply flows were calculated for each neighborhood and its respective zones. These data were correlated and the results obtained were specialized in the form of thematic maps. It was observed that the minimum flow of demand supply is inversely populational to the population density, while this flow is directly proportional to the population and the compactness index of the urban area.
