Description

Contaminated sediment mobility plays an important role in river engineering and water resources management. Numerical models are powerful tools to be used for analysis, prediction and remediation issues in sediment management. Erosion stability plays a key role for contaminated sediment mobility assessment. Experimental investigations on erosion stability of undisturbed sediments reveal a large spatial variability of sediment properties. A 1-d and a 2-d numerical transport model is applied to analyse erosion and sedimentation processes of contaminated sediments in the Upper River Rhine reservoirs and in the river Elbe focussing on the effect of the near bank low flowing water zones.
