This work presents a geophysical study of part of the riverbank subject to erosion, with the primary objective of evaluating its use in the detection of areas degraded by erosion in a critical stage, before its collapse. This area is located along 600 m along the Guamá River, between the Tucunduba River Bridge and the Canoeing Port, within the campus of the Federal University of Pará (UFPA), in the city of Belém in the State of Pará (Brazil). It has, in some sections, different types of erosion containment, including concrete wall and cement bags. The geophysical method was used: Spontaneous Potential (SP). The measurements were taken during low tide and high tide in an attempt to map the preferential subsurface paths for the entry of water brought in by high tide and, through this means, for work. erosive. The results demonstrate that Geophysics can be an auxiliary tool in the prediction of places where the erosive fall of the terrain caused by it is about to occur.
