Comportamento morfológico e sedimentar das Praias do Litoral Leste de Acaraú, Ceará

Abstract

This research aimed to morphological and sedimentological analysis, characterizing the granulometry of the east coast of Acaraú beaches. The methodology adopted for carrying out the profiles was used a DGPS receiver that consisted of measuring the position of the longitudinal profile of the waterline. For sedimentological analysis was performed using the statistical parameters in accordance with the method of Folk; Ward (1957) and software ANASED for classifying samples of each profile. The results were interpreted in accordance with the behavior of praial morphology, noting that deposition areas exceeded erosion rates in the monitored month. In sedimentological analysis were found a better degree of grain selection in the profiles 3-6 and selected poorly presenting medium grain to coarse grained in profiles 1 and 2.
