Itaueira

Itaueira takes its name from a river of the Piauí interior. Rising in the Serra das Confusões, the Itaueira flows through a dry country of caatinga vegetation before joining the Parnaíba. Its waters are intermittent, reflecting the contrast between the rainy season and the long dry months. Together with the Uíca and Salinas, it forms part of the local network of rivers draining toward the Parnaíba.
