Denudation Rate Changes Along a Fast‐Eroding Mountainous River With Slate Headwaters in Taiwan From 10Be (Meteoric)/9Be Ratios
Deng, Kai; Yang, Shouye; von Blanckenburg, Friedhelm; Wittmann, Hella (Journal of Geophysical Research: Earth Surface, 2020-02-18)The novel 10Be (meteoric)/9Be system, where 10Be is delivered by precipitation and stable 9Be is released by weathering, provides denudation rates over weathering‐erosion timescales. The new tool is applicable to quartz‐poor ... -
Sediment Transit Time and Floodplain Storage Dynamics in Alluvial Rivers Revealed by Meteoric 10Be
Repasch, Marisa; Wittmann, Hella; Scheingross, Joel S.; Sachse, Dirk; Szupiany, Ricardo; Orfeo, Oscar; Fuchs, Margret; Hovius, Niels (Journal of Geophysical Research: Earth Surface, 2020)Quantifying the time scales of sediment transport and storage through river systems is fundamental for understanding weathering processes, biogeochemical cycling, and improving watershed management, but measuring sediment ... -
Temporal evolution of headwall erosion rates derived from cosmogenic nuclide concentrations in the medial moraines of Glacier d'Otemma, Switzerland
Wetterauer, Katharina; Scherler, Dirk; Anderson, Leif S.; Wittmann, Hella (Earth Surface Processes and Landforms, 2022-05-03)Climate change affects the stability and erosion of high‐alpine rock walls above glaciers (headwalls) that deliver debris to glacier surfaces. Since supraglacial debris in the ablation zone alters the melt behaviour of the ...
