dc.description.abstractThe interaction between global factors tglobal" glacio-eustatic sea-leve/ rise) and regional factors (tectonic trend, oceanographic factor) is analyzed in different areas of the lberian and Canary lsland littora/. Sea-leve/ changes and climatic variations are stated for the Mediterranean and Atlantic littora/s, with different tidal ranges and tectonic trends. Different stages can be envisaged in the coastal evolution of a/most ali the analyzed areas from the beginning of Holocene (10.000 BP): at ca. 7.000 BP (Flandrian maximum) with a change from open estuaries to aggradational processes (Cádiz Gulf, subsiding area), basal peat (Valencia Gulf, subsiding area) and development of microcliffs (Mediterranean uplifting areas). From 7,000 to 2,700 BP a first progradation phase with development of spit bars took place in the mediterranean uplifting areas, whilst in the atlantic subsiding one starts the aggradation processes in the formerly open estuaries, an a/so from ca.4,000 BP development of spit-bar system. A second progradation phase ofthe spit bars systems occurs between 2,400 and 500 BP both in Almería and Cádiz Gulf, where a change from aggradation to progradation takes place in the estuary environments, and with a change in the direction of /ongshore drift (Mediterranean) and prevailing winds (both areas) at ca.2,400 BP. At ca. 1,200 BP a sudden paleogeographic change took place in estuary environments. From 500 BP up to now a marked increase of coastal progradation in ali littorals is observed. Climatic interpretations /ed to corre/ate anticyclonic conditions (as it happened during Little Ice Ages) with the growing of spit bar systems and progradation, while low pressure conditions (as during Medieval Warm Period) coincides with no progradation. In the Canary lslands, the development of storm ridges at ca. 3,500 BP can be corre/ated with an intensification of trade winds.en
