Abstract
Coastal and inner shelf marine areas are usually studied separately, although the hydrodynamics processes, sediment transport and relief morphology in both regions are closely related, with complex interactions between them. Topo-bathymetric and physical oceanographic surveys on south of Gran Canaria beaches and inner shelf show as sediment fluxes through inner shelf affect the sedimentary dynamics on beaches. Moreover, high resolution seismic profiles recorded in this insular shelf and the continental shelf of the gulf of Valencia show that previous paleo-relieves, determined by continental or coastal processes, influences the shelf roughness and morphology, which affects to present hydrographic processes and sedimentary thickness in the insular and continental shelves during the Holocene. Therefore, morpho-sedimentary evolution of the littoral and shelf are also closely related.
