Análise das feições geomorfológlicas e dos processos morfodinâmicos na evolução do sítio urbano de Garanhuns-PE

Abstract

The present research has the aim of analyzing the inter relations of the geomorphologic features and the morph dynamic processes in the evolution of the urban site from Garanhuns-PE. This way, supplying subsides for the implantations of public policies, which contemplate the implantation of a model of usage and sustainable occupation of soil. During the research, technologies of remote sensing and SIG were used, to create a referential geologic data bank which was supplied by matricidal data from INPE/DGI, INCRA and |Banco de Dados Geomorfométricos| from Brazil, SRTM archives from EMBRAPA (Project Brazil in Landscape) and vectorial information from CPRM and IBGE. What makes possible the interpretation of the space phenomena which are occurring in the studied perimeter and represent them through Thematic Letters and 3D Images. From the referred maps and 3D models, it was possible to make the correlations between the physical features of the geographic space and its action system. Making possible the identification and monitoring from the public departments of the main risk areas, to the human occupation of the landscape because of the susceptibility to the morph dynamic process. Among the areas, these are highlighted: Liberdade, Heliópolis, Novo Heliópolis, Parque Fênix, COHAB III, São José, Santo Antônio and Magano. Since their high rate of susceptibility to mass movements.
