Avaliação da Influência do Uso e Ocupação do Solo com a Geração de Escoamento Superficial em Duas Bacias Urbanas
Abstract
As problems due to urbanization became more complex, several studies have emerged to understand how to solve them. It is understood that low-impact urbanization can generate a more favorable situation for human occupation. With this situation and seeking to corroborate with studies involving problems of flooding and land use and occupation, this work analyzes the urban sub-basins of Mandacaru and Maringá streams. These sub-basins present distinct occupations and therefore, allow a comparative analysis. Through hydrological modeling future rain scenarios were modeled and with the results it was observed that the sub-basin of the Mandacaru Stream can present, in high frequency events, a flow rate per area greater than 26 % when compared with the sub-basin of the Maringá Stream. Furthermore, it was found that lower urban occupation can generate more tenuous effects in increasing river flows and, consequently, reduce flood risks.
