  abstract = {{F}luvial terraces are valuable records to study and characterize landscape evolution and river response to base level lowering, and to decipher coupled responses between fluvial incision and regional tectonics. {T}he opening of closed basins has a strong impact on fluvial dynamics, as it involves an abrupt base level lowering that accelerates landscape fluvial dissection. {T}his study focuses on the time response of the {D}uero {B}asin, the largest and best preserved among the {C}enozoic basins of the {I}berian {P}eninsula, to exorheism. {F}luvial incision due to basin opening has developed up to 13 un-paired strath terraces along the south margin of the {D}uero river, distributed at relative heights up to + 136-128 m compared to the modern floodplain. {P}aired {B}e-10-{A}l-26 cosmogenic isotope depth profiles from six fluvial terraces, located ca. 30-80 km upstream from the opening zone, suggest {P}leistocene ages for almost the entire fluvial terrace staircase (from {T}3 at +112 -107 m, to {T}12 at + 13-11 m). {T}he terrace density and the total lowering of the terrace surface, key parameters in limiting terrace exposure ages, were estimated based on field and geomorphological data. {A}pparent burial durations and basin denudation rates deduced from inherited {B}e-10-{A}l-26 concentrations provide valuable information on basin evolution. {A}pparent basin denudation rates remained relatively low (< 3-6 m.{M}a(-1)) during the {P}liocene, and doubled (8-13 m.{M}a(-1)) during the {E}arly {P}leistocene (ca. 2-1 {M}a) possibly showing a lower proportion of recycled sediments. {T}ime averaged incision rates deduced from terraces in the study area and along some tributaries show that incision rates are higher close to the opening site (122- < 250 m.{M}a(-1)) than towards the upstream part of the catchment (88-68 m.{M}a(-1)), evidencing the retrogressive travel of the erosive wave nucleated at the opening site.},
