Erodibilidade de solos tropicais não saturados nos municípios de Senador Canedo e Bonfinópolis (GO). Geociências, São Paulo, v. 34, n. 3, p. 441-451, 2015.http://repositorio.bc.ufg.br/handle/ri/20096The climate, relief, soil type and the use and ocupation of land are important to understand the susceptibility of land to erosion. Only analyzing the soil, researchs show the suction importance in the soil strenght to erodibility. In this way, the present study aims to analyze the suction effect in erodibility of two soils with distinct weathering degree. Therefore, two areas near the city of Goiânia were selected, corresponding to a Cambisol soil type and a Oxisol type. With the aim to understand the erodibility of these materials Inderbitzen tests and slanking tests were carried out in undisturbed samples, with differents initials degree of saturation. The test results show the samples with lower initial suctions were more resistance to laminar erosions and slope stability when submerged and the suction effect changes with weathering degree. However, the wetting process influenced the erosion intensity. Therefore, the soil erodibility isn't only associated to physics and mineralogy characterization, but depends of the way and the intensity.porAcesso AbertoErodibilityErodibilidadeTropical unsaturated soilsSuctionInderbitzen testSlaking testSolos tropicais não saturadosEnsaio de desagregaçãoSucçãoEnsaio de inderbitzenArtigo
