- Abstract
The urban expansion phenomenon on small and medium-sized cities in Brazil has given in several geomorphological environments notable changes in their operation and break boundaries, promoting rapid responses, directly on the landscape stability. This work aims to analyze, on a spatial-temporal perspective, changes caused by land use over more than four decades occurred in Garanhuns-PE municipality. With visitation recognition and interpretation of the meaning of the current dynamic process, the morphodynamic mapping in scale space-time led to recognize several surface processes related to topography, litho-pedological structure and vegetation cover. The sedimentology and mineralogy of the analyzed material showed that the process of erosion and transport in the short term, has favored a buildup of deposits of coarse texture and inversion of relief in low slope areas from the formation of new knickpoints. Thus, it was possible to establish a strong relationship between human activities and the increase of landscape sensitivity, especially when related to changes in the climate system, operating in different time frames.
