Morfodinâmica e Sedimentologia Recentes da Planície de Marés do Rio Barra Nova, Município de Caucaia, Ceará

Abstract

The Barra Nova River is a small drainage finding the sea in the coastal zone of Caucaia (Ceará State, Brazil), where it enlarges in a tidal plain known as "Lagoa" of Barra Nova. It is a very dynamic system, recognized by the frequent change in size and position of its morphologies, but also by its use as a recreation area and for the practice of water sports. It is, therefore, an area of interest from the scientific and environmental viewpoints, being in the latter subject related to the need for sustainable use by visitors and tourists. In this context, it was proposed here the analysis of variations of its constituent features (forms) through the examination of satellite images and aerial photographs, surveying topographic features in two semesters of the same year (2018) on the barrier and the textural study of terrigenous and bioclastic components and their organic matter content.
