This work aimed to evaluate the relief features of the Taturi River watershed Paraná state, Brazil, seeking to identify the interrelationship between the lithologies, the linear features linked to fractures and faults, erosive features and types of landforms. For that, the geomorphological mapping of the area and the survey of morphostructural data were cattied out, through the elaboration of the drainage density, dissection depth, slope and lineation maps. The analysis of these maps made it possible to identify different sectors, mostly determined by the lithological variation and by the lineaments. In this way, the hydrographic basin of the Taturi River, despite its low slope morphology, has morphological and, therefore, varied procedural characteristics, wich are linked to lithology and lineaments. Thus, the domain sectors of sandy lithologies present morphologies that indicate greater intensity of erosive processes, which must be considered when using and occupying the land.
