| الوصف: | The Confusão do Rio Preto Range, located on the north-central Quirinópolis (GO), present tabular residual hills with elevations about 880 m. In the higher parts of the range occur sizable erosive scars, like rills and gullies. The research aimed to identify the origin, controlling factors and dynamics of the processes responsible by the formation and evolution of a gully in pasture area on the referred range. First, was realized the registration of the erosive feature and the selection of 17 profiles along the banks of the gully to describe, in top sequence, the horizons cut by the erosion. The obtained data allows to state that the gully is developing on an old erosive scar, mainly conditioned by: 1) surface runoff concentrated in cattle trails in the surroundings of the incision; 2) surface runoff concentrated in channels of terraces, that overflows and reaches the borders of the erosive feature; and 3) exfiltration of the subsurface water in the contact of the Bw and Bc horizons with the underlying C horizon in the strongly inclined banks. Before the prevision of fast lateral and backward expansion, is necessary to adopt practices for control and stabilization of the gully ; La Sierra de la Confusão do Rio Preto, situada en el centro norte de Quirinópolis (GO), presenta mesas residualesaltitudes en torno de los 880 m. En las partes más altas de la sierra, ocurren cicatrices erosivas de porte considerable, como cárcavas y barrancos. El objetivo de la investigación fue identificar el origen, los factores controladores y la dinámica de los procesos responsables por la formación y evolución de un barranco en área de pastoreo en la referida sierra. Primero, se realizó el catastro de el rasgo erosivo y la selección de 17 perfiles a lo largo de los taludes de lo barranco para describir, en toposecuencia, los horizontes seccionados por la erosión. Los datos obtenidos permiten afirmar que el barranco se está desarrollando sobre una antigua cicatriz erosiva, condicionado principalmente por: 1) flujos superficiales ... |
