Análise dos Indicadores do Processo Erosivo no Litoral do Município de Icapuí, Ceará, Nordeste do Brasil

Abstract

The present study aimed to analyze the erosion process in part of the coast of the municipality of Icapuí, east coast of Ceará. The methodology consisted of the analysis and identification of coastal erosion indicators and their causes by means of a satellite image from 2009 and during stages of field monitoring in 2016 with the use of a DGPS receiver. 8 indicators and 6 anthropic causes of erosive processes were identified over the 6 km monitored. Such indicators are more evident on the beaches of Barreiras de Baixo and Barrinha, located on the west coast of the municipality in question, where erosion has already caused serious damage to the buildings and its causes are directly related to the local hydrodynamic characteristics and structural interventions that are carried out. present in the study area. A progradant stretch was observed in part of the Barreiras de Cima beach, which is still protected by the presence of frontal dunes. This type of analysis proved to be effective as a tool to be used for coastal management purposes in order to identify erosion indicators and their causes, thus allowing better planning for actions to contain and / or mitigate the problem of coastal erosion.
