Abstract
In recent decades, the growth of urbanization has caused great transformations in the social, economic and morphological aspects in the coastal areas. The urban beaches of Boa Viagem and Pina (Recife-PE) and the beach of Piedade (Jaboatão dos Guararapes-PE), have presented these aspects, where coastal vulnerability to erosion is observed. The objective of this work is to analyze the spatial and temporal displacement of the shoreline. For this, the several data obtained from the kinematic relative geodetic survey method was modeled, which allows the monitoring of the shoreline for the years 2007, 2009, 2010 and 2012. The method of transects was used, which is necessary to adopt a shoreline as base, year 2007. The study area was divided into 6 sectors to analyze the average displacement of the shoreline. Sectors 1 and 5 presented accretion in all periods analyzed (2007-2009, 2007-2010, and 2007-2012). Sector 2 presented erosion in all periods analyzed. The sectors 3 and 6 in the periods 2007-2009 and 2007-2010, presented erosion, while from 2007-2012 they presented the tended to accretion. Stand out that in sector 4 the calculation was not made due to the fact that it is the area that presents rockfill. This study tends to contribute to the analysis of temporal behavior in decision-making projects in coastal environments.
