Abstract

The aim of this study was to quantify the downstream fluxes of clay, silt, sand, gravel and cobbles through the Rhine between 1991 and 2010 and to identify the sources and sinks of these sediments. This was done by analysing a unique dataset containing thousands of sediment transport measurements and by evaluating the sediment budget. It is highlighted that 68% of gravel and sand flux is caused by anthropogenic bed erosion and gravel supply. Sediment fluxes change abruptly where the river bed becomes sandy. Bed erosion is high in areas with shallow Tertiary sand or mining-induced subsidence. Transfer rate of sand and gravel to the Rhine delta did not change despite human impact
