Description :
In this study, the AA. analysed the combined effect of human activities on the flow and bed-sediment characteristics of the River Waal during the past 900 years. The AA. focus on 2 characteristics with a great geomorphological importance : the bed shear stress and the bed grain size. Various data types were used, such as borehole descriptions, historical river maps and modern hydraulic data. In the discussion the causes of the historical change in bed shear stress and bed grain size are identified and compared with observations in other rivers. Finally, it is shown how historical grain size information can be used for river restoration purposes.
