The influence of floodplain morphology and river works on spatial patterns of overbank deposition

Floodplain topography and related hydraulic patterns of overbank flow constitute a major control on the amounts and patterns of sediment deposition on floodplains. We studied the differences in sediment deposition at two scales along two river branches of the lower River Rhine in the Netherlands: the Waal and IJssel River. Human alterations like levelling and embankment construction have severely impacted the floodplains along the Waal River branch (average discharge: 1500 m3·s–1), whereas the relatively wide floodplains along the IJssel River (average discharge: 250 m3·s–1) still exhibit thei...
