Through disordered urban growth, areas of slopes with high slopes were occupied, which causes a reduction in vegetation cover, increases the occurrence of soil erosion, and generates slope instability. Objective: To analyze studies on tests that verify the erodibility potential of soils that are commonly used, through a systematic literature review. Methodology: The search was carried out in four databases (Scopus, Science Direct, Web of Science, and Google Academic) to search for articles, limited to scientific articles and book chapters in the field of civil engineering in the last 10 years. Relevance: Given the importance of studying the erodibility of soils in risk areas, a compilation of which tests are used for this purpose can help researchers on the subject choose the most appropriate test for this purpose. Results: Of the 124 articles selected, 36 were considered for data extraction. There are various tests to check the erodibility potential of a given soil and monitor risk areas, classified as direct methods (Inderbtzen and rain simulator) and indirect methods (drone, Crumb test, pinhole test, and Miniature Compacted Tropical - MCT). Contributions: All methods proved to be effective for analyzing the erodibility of slopes in risk areas, contributing to the stabilization of the area. Indirect methods require associations between assays to obtain reliable results. Of these methods, the drone brings a technological innovation that is capable of expanding the understanding of risk areas and sediment transport.
