AB Knowledge of the evolution of Spanish fluvial networks has improved during recent years as more river systems have been studied andmore geochronological data has become available. However, the chronological framework is a major issue as the range of applications islimited by methodological constraints and spatial coverage is sparse. Integration of ‘absolute’ dating methods with biostratigraphy andpalaeomagnetism permits the recent evolution of these river systems to be reviewed. The timing of incision from the Late Neogene to thepresent varies between the major Iberian fluvial systems, depending on the substrata and tectonic settings. Early Pleistocene and olderfluvial sequences in the core areas of the Iberian Peninsula provide a more extensive record of fluvial evolution and are better preservedthan the terrace flights in the coastal lowlands. Middle Pleistocene sequences are well developed in most of the major river systems inIberia, particularly those of the Tajo, Guadalquivir and Aguas River, and frequently represent the principal climatic cycles of thatperiod, although tectonic and sea-level effects can also be seen. For Late Pleistocene to Holocene times, the scheme becomes morecomplex. Our review suggests that each river system has responded differently to local and regional climate control, glacial andperiglacial processes in headwaters in high mountain areas, glacio-eustatic sea-level changes and local and regional tectonic patterns.
