|The Rwenzori Mountains and adjacent rift flanks represent the highest uplift of rift flanks on Earth and
its uplift may have signifiantly contributed to the aridisation of East Africa since the Late Miocene.
Within this project aims to reconstruct the erosional evolution of the Rwenzori Mountains since
their extreme uplift using topographic properties, cosmogenic nuclides (10Be) and alluvial sediments. Based
on remote sensing, representative localities of active erosion and exposures of river terraces or the proximal
basin fill will be selected for field studies. Suitable outcrops will be studied with respect to sedimentology
and fluvial dynamics. OSL (optically stimulated luminescence) dating will deliver a time frame for the younger
alluvial deposits. A highly resolved DEM - Digital Elevation Models (30 m) is used to analyse the landscape morphometry of the rift
flanks and its dependence on uplift rates, rainfall distribution, erodibility of bedrocks, and denudation
rates. Specific attention is paid to identify neotectonic movements. The controlling factors of erosion will
be explored by field mapping, GIS analysis and numerical experiments using a suitable computer code of
existing surface process models. Finally, the results will be integrated into an evolutionary model of
erosion, sediment flux, and rift basin fill for the central western branch of the East African Rift.
