This data were divided by its quartiles and used to classify each area, according the risk. The results are represented by two thematic maps containing a visual analysis of the risk; besides that, statistical data regarding the distribution of morphometric values in studied region. The generated maps can be used to explain the occurrence of natural disasters and explicate the demand of interventions by the responsible organizations of natural hazard.
