The modeling was elaborated through the algebra of maps as slope, hypsometry, drainage density, and land use, which were normalized between 1 and 5. The levels of influence, or grades, were assigned to the maps through the HPA correlation matrix. The processing results were four degrees of susceptibility for the study area, which vary from very low to high, according to the location and morphological characteristics of the terrain. The results are essential to model natural and anthropic aspects in urban areas. They can be used and applied, also, to model different phenomena and variables in other spaces.16engHierarchical Process AnalysisWatershedLandscape cartographyArtigo10.22409/GEOgraphia2022.v24i53.a47218WOS:000938686000001
