摘要：: In Plateau Palmas (PR) / Água Doce (SC) was carried out a morphostructural analysis of the drainage network. To obtain these results we performed field and laboratory work. On field were established density and orientation (azimuth) of 18 joints rock outcroppings. In Laboratory through photointerpretation it was made drainage map in scale 1: 25,000, from the analysis of the drainage network were individualized negative lineaments, anomalous bends and drainage elbows. Knowing the orientation of the negative lineaments, as well as the first order channels, from the inferred faults and joints of rocks were made rosette charts. The comparison of the degree of directional correlation between such features demonstrates that both have predominant orientation NW, coinciding with the orientation of the tectonic lineament Iguaçu River. Thus, it was concluded that the relief of the Plateau of Palmas (PR) / Água Doce (SC) is influenced by this major structural feature.
