PROCESSO DE VOÇOROCAMENTO E FEIÇÕES SECUNDÁRIAS: UM ESTUDO DE CASO EM MANAUS-AM

Abstract

Gullies are erosive incisions that arise through natural and human actions, modifying the landscape. Thus, for this work, the gully located in the Nova Cidade district was chosen for further details. In this, the characterization of the morphometric parameters (type, shape and size), and the rework features were carried out, as well as the identification of their environmental impacts. For this purpose, it was established parameters were used to classify the gully in terms of “type”, “shape”, “size” carried out in field work. In summary, the incision in question is of the connected type, has an irregular shape and had an eroded volume of 119,981.52 m³, presenting as main reworking features inside, the kettles and regression alcoves. Among the various impacts caused by the gully is the loss of soil and silting of the channel downstream.
