The transportability of each type of sediment by runoff and its potential for subsequent deposition largely depends on its morphological features and particle size distribution. The aim of this study is to describe and characterize the morphology and micromorphology of sediments deposited in a reforested area and to understand the dynamics of the transport process. In order to understand the sedimentation processes, the following analyses were performed: particle size distribution, with and without the use of a dispersant solution; statistical analysis of the sand fraction using Folk and Ward parameters; sediment and soil micromorphology; and two-dimensional distribution and geometry of soil horizons and sediments. The sedimentation occurred in a localized and discontinuous manner and in the lowest parts of the landscape. The sediments were generated by low intensity erosive events producing well-sorted sediments and the clay in these deposits was transported mainly in the form of silt-sized clay aggregates. Microscopic analysis of the sediments was important for clarifying the genesis and transport dynamics of the sedimentary deposits.</p></div>
