The well-exposed systems of prograding beach ridges on the Carchuna–Calahonda (Granada) and Campo de
Dalías–Roquetas (Almería) coastal plains continue offshore as infralittoral prograding wedges (IPW). The
Holocene IPW is a narrow morpho-sedimentary unit up to 2.5 km wide which develops seaward from the
lower edge of the shoreface to 15–20 m depth, extending to a well-defined break of slope at water depths of
35–40 m. These IPWs have been recognized and studied using very high-resolution seismic profiles (TOPAS)
and multibeam data (EM-3000D). In detail they are complex morpho-sedimentary units in which internal
structures are closely linked to the pattern of progradation of the adjacent coastal plains. When longshore
currents produce significant littoral drift, the IPWs are composed of several minor units arranged in offlap,
which accrete parallel or oblique to the main shoreline. Therefore, it is possible to correlate progradational
units in the coastal plain (H-units, sensu[Goy, J.L., Zazo, C., Dabrio, C.J., 2003. A beach-ridge progradation

Mediterranean). Geomorphology 50, 251–268]) and subunits in the IPW, but special care is required
depending on the local arrangement of morpho-sedimentary units. Besides, it is not realistic to draw
conclusions regarding the age of the subunits inside a given IPW without adequate dating, as the number of
subunits will greatly vary from place to place depending on local factors, magnitude of sea-level oscillations,
and sediment supply.
