Resumo
Terraces have the purpose of retaining and infiltrating, or slowly draining the waters from the upper launcher portion, in order to minimize the erosive power of the floods. The objective of this work was evaluate the reduction expected in ridges and terraces due to the structural rearrangement of different soil classes. Samples were collected from three classes of soils in an approximate volume of 20 liters, in the city of Campestre de Goiás e Palmeiras de Goiás, GO. Each soil class represented a treatment, being T1 - Red Latosol; T2 - Yellow Latosol and T3 - Displastic Haplic Cambisol.The soil of each class was conditioning, without compaction or agitation, in seven containers made of Polyvinyl Chloride (PVC) with dimensions of 250 mm in diameter and 250 mm in height. After the fill of all the containers, a daily addition of water blade was performed to them. The variables analyzed in the treatments were the height and soil density in the containers. These evaluations were repeated every week until the end of the rain simulation. The reduction of terrace in each class of soil was quantified by the difference of initial and final height of the soil in the containers and the density by mean of relation between mass and soil volume. The results showed for the conditions under study that there was a significant difference for soil abatement, in which the cambisol presented a higher mean value of 5.8% abatement and observed that the humidity increased linearly during the twenty days analyzed.
