Resumo(s)
The deep submarine valley near Setúbal that connects the continental platform to the Tagus Abyssal Plain is a submarine canyon
of the type commonly knows as Gouf. In this article we try to show the tectonic influence in its formation and in the installation of its submarine hydrographic net. Some indirect evidences of erosive processes responsible for the formation of typical submarine forms of canyons are analysed based in the interpretation of the batimetric map. Finally, we try to give a brief idea of the evolution of this canyon based on the knowledge that is accepted for the area where he belongs.
