Proposta de análise empírica da instabilidade potencial do relevo em estudos integrados

Abstract

The present paper, in the light of theory and practice, is constituted by a proposition, application and assessment of a methodology of an empirical relief analysis, being based on integrated studies milieu. As an area to be focused, the Tabuazeiro Topomorphological Unit was chosen, being located in the Central Massif of Vitoria, which is in the island part of the Brazilian state of Espirito Santo. Geological, pedological and geomorphological data were collected as well as morphodynamical features, that are associated with the use of the soil and its occupancy. Later on, these aspects were correlated in a GIS (Geographic Information System) environment, in distinct degrees of potential instability of the relief, being espacially distributed, according to a model known as the Potential Relief Instability Chart. As opposed to this fact, that model corresponds to an empirical approximation regarding the comprehension of current geomorphodynamical processes, active in the relief, and its correlations with the ways of use and occupancy of the soil in the past and in present days. These factors were relevant to conduct the physical-territorial city planning, which better squares with the specifities of the geomorphological site in study.
