Evaluation of the morphodynamic criteria for the diagnostic phase of Projeto Orla: a case study on sandy beaches with river mouths

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