Description
Summary:The evolution of the drainage system is driven by influence structural and changes in the climatic regime resulting in specific morphological features.We studied one of these features – drainage anomalies – in the middle valley of Paraíba do Sul River (RJ/SP), the influence exerted by the lithology and drainage system rearrangement.We identified many morphotectonic features (knickpoints, flat drainage dividers, and low drainage dividers with or without drainage capture) using topographic charts and a geomorphological map Silva (2002), and we also analyzed theirspatial distribution to establish a reliable relationship between the drainage anomalies and the substract characteristics. Most of the drainage anomalies the Paraíba do Sul Middle Valley Intra-plateauDepression (Depressão Interplanáltica Médio Paraíba do Sul - DIMPS) and show a significant structural control.
