IDENTIFICAÇÃO DE DEPÓSITOS FLUVIAIS E DESCONECTIVIDADES ANTRÓPICAS NO BAIXO CURSO DO RIO UNA – PE

There was the identification of the types of river deposits existing in the lower course of the river Una, as well as anthropic disconnectivities, since these influence the configuration of the deposits, as well as the river dynamics. The first stage of the fluvial styles proposal was used (BRIERLEY and FRYIRS, 2005), relating to the categorization of valley confinement as the primary factor of the channel morphology. From this, it was possible to identify stretches of channels where river deposits are found. Features were identified through PE3D images and field activities, and a detailed mapping of these deposits was carried out. Finally, the main elements of anthropic disconnectivity present in the lower course of the Una River were located, seeking to associate how they can modify the natural dynamics of the channel, forcing it to seek new base levels and adjustments.
