Este trabalho apresenta os resultados da análise morfométrica realizada na rede de drenagem associada à cratera de impacto de Vista Alegre, município de Coronel Vivida, Sudoeste do Paraná. A cratera meteorítica, localizada no planalto basáltico da Bacia do Paraná, possui 9,5 km de diâmetro e a diferença altimétrica entre o centro e borda é de aproximadamente 300 m. A cratera é cortada pelo rio Chopim (130 m de largura) no seu extremo oeste. Os afluentes da margem direita deste rio, os córregos Lambedor, Quieto e Mirim são objetos da análise morfométrica neste estudo. Os dois primeiros córregos drenam a depressão anelar e o último drena terrenos fora da cratera. A medição das variáveis morfométricas das bacias foi realizada com auxílio do programa Global Mapper a partir de cartas topográficas digitalizadas com escala 1/50.000 (Folhas Coronel Vivida e Verê). As redes de drenagem analisadas apresentam padrão dendrítico e os índices morfométicos das bacias instaladas dentro e fora da estrutura apresentam valores similares, mostrando a pouca influência da cratera sobre organização do atual padrão de drenagem. Um modelo conceitual é proposto para explicar a evolução do padrão de drenagem.Downloads
