| description | Water is one of the most important resources for the survival of living beings, and must be very well managed, so as not to compromise the quality of life of future generations. One of the biggest challenges is to reduce the effects of water deficiency and contamination. The objective of this work is to establish a classification of the vulnerability to the contamination of surface waters, aiming to contribute with the more effective management of the hydrographic basin of the Pirapó - Paraná River. For this, a semi-empirical model of Morgan, Morgan and Fenney (MMF - modified) was applied. The results show that vulnerability to surface water contamination showed a higher percentage linked to the average vulnerability, corresponding to approximately 63% of the basin area. This classification is related to the occurrence of deep soils (Oxisols and Nitosols) and resistant to the release of particles, with lower values of surface runoff influenced by the reduction in the intensity of precipitation, in addition to being over moderate slope areas, with a predominance of classes between 6 and 15%. Thus, it is considered that the study may contribute to the development of more favorable actions for the protection of surface waters in the basin, prioritizing specific areas of protection for the monitoring of its waters. |

A água é um dos recursos mais importantes para a sobrevivência dos seres vivos, devendo ser muito bem gerida, de modo a não comprometer a qualidade de vida das gerações futuras. Um dos maiores desafios é diminuir os efeitos da carência e contaminação da água. O objetivo desse trabalho é estabelecer uma classificação da vulnerabilidade à contaminação das águas superficiais, visando contribuir com a gestão mais efetiva da bacia hidrográfica do rio Pirapó – Paraná. Para isso foi aplicado o modelo semi-empírico de Morgan, Morgan e Fenney (MMF – modificado). Os resultados mostram que vulnerabilidade à contaminação das águas superficiais apresentou maior porcentagem ligada à vulnerabilidade média, corresponde cerca de 63% da área da bacia. Essa classificação, está relacionada a ocorrência de solos profundos (Latossolos e Nitossolos) e resistentes ao desprendimento de partículas, com valores mais baixos de escoamento superficial influenciados pela redução na intensidade da precipitação, além de estar sobre áreas de declividade moderadas, com predomino de classes ente 6 e 15%. Assim, considera-se que o estudo possa contribuir no desenvolvimento ações favoráveis a proteção das águas superficiais da bacia, priorizando áreas específicas de proteção para o monitoramento de suas águas. 2020-12-24 2022-03-17T15:14:45Z 2022-03-17T15:14:45Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/162662 10.11606/eISSN.2236-2878.rdg.2020.162662 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/42354 por https://www.revistas.usp.br/rdg/article/view/162662/166523 Copyright (c) 2020 Carlos Henrique da Graça, Hélio Silveira http://creativecommons.org/licenses/by-nc-sa/4.0/ application/pdf Universidade de São Paulo.
