Ocorrência de depressões fechadas em divisores de drenagem no Médio Vale do Rio Paraíba do Sul

Abstract

Closed depressions are proto-valleys that show absence of a channel outlet flow of surface water. Many studies show that the closed depressions are formed by geochemist denudation. In the Paraiba do Sul River Middle Valley, these forms are spatially non-uniform, occurring more frequently on the Mantiqueira range. Such characteristics suggest that the studied basins on the Mantiqueira range, chemical denudation processes are significant, while previous studies on the Serra do Mar range indicate the dominance of mechanical processes.
