AbstractMost Mediterranean prodeltas show undulated sediments on the foresets of their Holocene wedges. These features have been described all along the Mediterranean and interpreted as either soft sediment deformation or, more recently, as sediment bedforms. We present a detailed analysis of these features using ultrahighresolution seismic and bathymetric data, as well as geotechnical information and hydrodynamic time series and hydrographic transects. We show that the characteristics of the sediment undulations (morphology and configuration of the reflections down section and between adjacent undulations) are incompatible with a genesis by sediment deformation. © Springer Science+Business Media B.V. 2012.
