Abstract
A presente pesquisa teve como objetivo apresentar os diferentes conceitos relativos a bacias hidrográficas e realizar a caracterização morfométrica da microbacia do córrego Marivan localizada no município de Araraquara (SP). Diferentes definições referentes ao conceito de bacias hidrográficas foram discutidas e sistematizadas. Para a caracterização morfométrica da microbacia do córrego Marivan foi utilizado um mapa topográfico na escala 1:10.000 cedido pelo Departamento Autônomo de Água e Esgoto de Araraquara (DAAE). Os resultados indicam que a microbacia do córrego Marivan é pouco ramificada, com uma área de 2,1 km² e perímetro de 5,37 km. O comprimento do canal principal é de 1,37 km com uma rede de drenagem total de 1,43 km. Possui uma baixa capacidade de drenagem e densidade hidrográfica. O fator de forma e o índice de circularidade indicam que o perímetro da bacia aproxima-se a um círculo, o que favorece os processos de inundação (cheias rápidas). Concluise que a análise de aspectos relacionados à drenagem, relevo e geologia pode levar à elucidação e compreensão de diversas questões associadas à dinâmica ambiental local, todavia nenhum desses índices, isoladamente, deve ser entendido como capaz de simplificar a complexa dinâmica da bacia, a qual inclusive tem magnitude temporal.
