Avaliação dos critérios morfodinâmicos para a fase de diagnóstico do projeto orla:um estudo de caso em praias arenosas com desembocaduras fluviais / Evaluation of the morphodynamic criteria for the diagnostic phase of Projeto Orla: a case study on sandy beaches with river mouths

Abstract

The aim of this study is to analyze part of diagnostic criteria of the integrated coastal managementproject (Projeto Orla), specifically considering the morphodynamics and physiography as justificationfor an analysis focused on the physical vulnerability. Therefore, this work was carried out on the coastarea close to the mouth of the Paraiba do Sul River, whose area is recognized by the intense instabilityand morphological stages of severe coastal erosion. The methodology for delineation of the shore, theestablishment of restricted or non-building areas and characterization of shore types, associated with theestablishment of Landscape Units were investigated. The application of these criteria indicated someweaknesses warning for the need of some adaptations related to the geomorphological characteristicsof the coast. Thus, suggestions were synthesized for adapting and complementing, for example, theapplication of geoindicators for performance evaluation of coast morphodynamic
