Abstract

Various approaches exist to quantify sediment fluxes on medium to large scales. These are: (1) river loads, (2) terrigenous cosmogenic nuclides, (3) stratigraphically controlled sediment volumes, (4) negative volumes of dissected landscapes, (5) exhumation rates from thermochronological data. Upcoming of new methods (2, 5) and the idea of dynamic coupling of uplift and denudation led to intense application of these methods over the last two decades. Definitely, the wealth of new data revolutionized our picture of rates at which earth surface processes and uplift operate over space and time. Less straightforward, however, is the progress in interpreting the mechanisms controlling these rates and to define the state of a source-sink system in terms of steady-state or unsteady-state equilibria. This key note aims at highlighting some of these problems with respect to flux rates resulting from different methods and still hardly understood differences of their spatial distribution. Some examples and possible hypothe- sis will complete the talk and may stimulate further discussion in the session.
