  abstract = {{D}espite a wealth of recent studies dealing with the evolution of the drainage network in the uplifted {A}rdennes massif ({E}. {B}elgium), especially from the {M}iddle {P}leistocene onwards, the {A}rdennian landscape evolution and long-term incision rates in the {M}euse catchment remain poorly documented over the whole {P}lio-{Q}uaternary. {A}lluvium-filled multilevel cave systems represent a relevant setting to unravel the {L}ate {C}enozoic history of re-gional river incision. {W}e present here a dataset of {A}l-26/{B}e-10 concentration data obtained from fifteen pebble samples washed into the {C}hawresse system, one of the largest multi-level cave systems of {B}elgium, which developed in {D}evonian limestones of the lower {O}urthe {V}alley, the main {A}rdennian tributary of the {M}euse. {T}he sample collection spans an elevation difference higher than 120 m and their depleted {A}l-26/{B}e-10 ratios yield burial ages ranging from-0.25 to 3.28 {M}a. {A}fter critical assessment of our dataset for intra-karstic reworking issues, the most striking outcome of the obtained burial ages is the acceleration by a factor five of the incision rates (from-30 to-150 m/{M}a) during the first half of the {M}iddle {P}leistocene. {I}ntegrating this incision peak and our pre-burial denudation rates, we then revisit the existing framework of {P}lio-{Q}uaternary denudation and river incision in the {A}rdennian {M}euse catchment. {W}hilst our {A}l-26/{B}e-10 concentration data shed new light on the temporal and spatial variability of the local river and hillslope system response to coupled tectonic and climatic forcings, it simultaneously highlights sampling issues and the need for further chronological data.},
