Identificação de anomalias através da aplicação do índice de Hack no canal principal do rio Ipanema - AL

Abstract

This work aims to identify anomalous sectors in the longitudinal profile in the drainage of the Ipanema river in Pernambuco and Alagoas, through the application of the Hack index, determining levels of rupture in the watershed areas, verifying how to apply this study and similar in the classroom. Twenty-four anomalies were identified throughout the course analyzed, as well as thresholds in the water body, largely due to the erosion process. The application of the Hack index in practice allows the geography content to be presented to students in a more dynamic and attractive way, not exempting the use of books and teaching resources. River basin studies should be prioritized because of their importance both as a natural resource and for ecosystem balance and in this context teachers are able to bring the topic closer to students by performing practical and integrative classroom activities.
