Avanço do mar em trechos de praias do litoral da Paraíba

Abstract

Considering that the dynamic between the continent and the ocean is constantly changing, either naturally or due to human action, it is common to observe numerous engineering devices to intervene in the preservation of the soil. The coast of Paraíba is approximately 133 km long, of which 26 km are part of the municipality of Pitimbu. The methodology used in the development of this work was the analysis of information collected in loco in two sections of the Pitimbu coastline. The first, located on the shore of Praia Azul at coordinates latitude: 7.493078°, and longitude -34.8170088° with an approximate extension of 2.8 km and the second, in Praia Ponta Coqueiros tip of coordinates latitude: -7.5168755 ° and longitude: -34.8077693 with an approximate extension of 1.6 km. The advance of the sea is at different levels in these highlighted intervals, so it is necessary to take different actions in each case, but as for the type of containment was recommended the construction of Bag Wall, because of the benefits of its use. The objective of this work was to evaluate the advance of the sea and study tidal containment methods that can be used in these areas.
