Zusammenfassung |
The topographic evolution of landscapes is substantially controlled by rivers, hence the
quantification of river incision rates is crucial to reconstruct the pace and pattern of landscape
formation. Most approaches to quantify river incision use geomorphic features like river
terraces and their elevation above today’s riverbed. This procedure works well, but is not
applicable if dateable terraces are absent. Our approach utilizes local and catchment wide
erosion rates derived from cosmogenic nuclides in combination with a digital elevation
model. The basic concept relies on the general observation of linear correlation between
hillslope angles and erosion rates for slopes |
