Dinámica de los canales submarinos del talud y el glacis continentales del Ebro (Mediterráneo-noroccidental) a partir de imágenes acústicas de alta resolución

Abstract

A comprehensive data set of the seafloor relief and superficial sedimentary cover on the Ebro progradational continental slope, NW Mediterranean Sea, reveals that its Late Quaternary building results from complex interrelationships between processes ranging from channel abandonment to incision of inner minor courses, from retrogressive erosion and channel capture to levee cutting and new channel opening, from channel wall sliding to shelf-edge and channel spillover. These processes succeed ones to the others both in time and space conforming a canibalistic frame where the balance between destructive and constructive processes is finally favourable to the last. They result in the formation of the channel-levee complexes characteristic of the Ebro continental slope and base-of-slope
