Summary

Along the wave-dominated Huelva coastline, south-west Spain, several types of mesotidal estuaries developed in the course of the Holocene transgression. Three different estuarine systems have been distinguished: (i) the drowned Guadiana fluvial valley; (ii) the Piedras estuarine lagoon; and (iii) the Odiel barrier estuary. The estuarine sequences include a number of depositional facies identified in field surveys and from sediment cores. They are grouped into an inner and an outer facies association. The inner facies association includes channels, lateral fluvial bars, active channel margins, salt marshes, sterile marshes and protected estuarine beaches. By contrast, the outer facies association incorporates sand spits, ebb-tidal deltas, open beaches and aeolian dunes. The individual facies are closely associated with critical tide levels (CTLs). The spatial distribution of the outer facies association along the three estuary mouths varies with respect to local sediment supply and process/product balance.
