Abstract

The river drains 2 interconnected Neogene sedimentary basins, the Sorbas and Almeria basins, and crosses 2 major geological structures, the Sierras de Alhamilla/Cabrera and the Carboneras Fault Zone. Regional epeirogenic uplift resulted in sustained fluvial incision during the Quaternary, punctuated by major climatically driven periods of aggradation and dissection, which created a suite of 5 river terraces. The river terrace sequence was radically modified in the late Pleistocene by a major river capture (itself a response to regional tectonics), localized tectonic activity and eustatic base-level change. The Rio Alias is defined by 4 reaches; within each the climatically-generated, region-wide, fluvial response was modified by tectonics, base-level change or river capture to varying degrees. The connectivity of the system from the headwaters to the coast decreased through time as incision progressed, resulting in changes in local coupling characteristics
