Atlas digital do meio físico de bacias hidrográficas urbanas do norte do Paraná

Abstract

Water, an essential resource for life and the functioning of ecosystems, has become a relevant issue due to its inadequate use and lack of ecological awareness. In view of this, there is a need for more sustainable development, with monitoring of water bodies, especially river basins, the subject of this work. River basins are very important because they are environmental planning units, where there is a need for their conservation and preservation. Thus, the objective of this work is to characterize the physical environment of urban river basins and produce a digital and interactive atlas. Two river basins in northern Paraná were chosen: Ribeirão Lindóia (covering the cities of Londrina, Cambé, and Ibiporã) and Parque da Raposa (in Apucarana). Using data collected online from sources such as FABDEM, FBDS, IAT, IBGE and IPPUL, in addition to the QGIS software tools, morphometric analyses were performed (such as the compactness coefficient, drainage density, shape factor and drenaige pattern), and thematic maps of contour lines, slope, pedology, hydrography, water bodies (lakes and reservoirs), springs and boundaries of the river basin were produced. These georeferenced data were added to an interactive online atlas using the uMap tool, the main product generated by this work, available at http://u.osmfr.org/m/1210861/. With the results of the morphometric analyses, Kc and Ff dictate that both basins are more elongated/irregular, the Dd calculation indicates a result in which the Parque da Raposa basin probably has a greater drainage capacity than that of the Ribeirão Lindóia and the drainage pattern is defined as dendritic for both basins. This work has therefore produced an easily accessible, interactive and public repository, so that there can be a clearer understanding of the conditions of these drainage basins, in order to contribute to decision-making processes in planning and management activities.
