摘要：The purpose of this work was to analyze the geomorphology of the Tarumã-Açú basin according to morphometric, slope, topographical parameters to understand the current dynamics of the basin geomorphological. Morphometric analysis indicated a low tendency to erosion in the Basin. The flat slope is located near the mouth of the Tarumã-Açú river and the largest slopes indicate terraces and dividers and most of the basin is characterized by small and medium hills (3-20 %). The basin has a strong structural control represented by a Strike-Slip Fault that controls the Tarumã-Açú River and the tributaries of left bank have lineaments and parallelism that may indicate tectonic control (dip-slip faults?) in an en enchelon system. It is also noted that the basin underwent tectonic tilting to the west, possibly indicating tectonic influence during the Cenozoic.
