This unit is either infilling former narrow channel sections, currently showing a terrace morphology (e.g. El Vedado), or insert on older morphopedosedimentary units with wide channel morphology (e.g. Salinero). It is composed of a sequence of slacked flood depositional units, centimetric in scale, with weak degree of soil development. The palaeoclimatic context is interpreted within a period of arid trend, characterised by a high hydroclimatic variability, and increase in the frequency of floods during Little Ice Age. Alluvial dynamics shows a high degree of geomorphic effectiveness as well as a very quick response to centennial scale climatic variabilityspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Alluvial activityLittle Ice AgeClimate changeCentral Ebro basinjournal articleopen access
