Análise da drenagem urbana e da erodibilidade do solo da Universidade Tecnológica Federal do Paraná – Campus Campo Mourão

Abstract

The objective of this study was to estimate soil losses due to water erosion in the surroundings of the Universidade Tecnológica Federal do Paraná, Campo Mourão Campus, and to compare it with data from the literature proposed by Bertoni & Lombardi Neto, as a way to assist in identification of the severity of erosion present on the site and the need for propositions of new urban drainage systems. The study was performed using annual statistical data of the last twenty-four years and maps of the factors of the universal revised soil loss equation (RUSLE) to estimate the loss. The value of soil loss by erodibility for Red Latosol was 9.42 ton / ha, which, according to the literature, does not determine a stability risk for foundations close to the site, with maximum loss parameters between 10.9 a 12.5 ton / ha. The result obtained, based on several authors, does not occur the need to implement a new urban drainage system, in contrast, when considering the aesthetic profile and the comfort of those who travel there, an adjacent system would be indicated to revert the problem.
