Deposition of contaminated sediments during high discharges is an important aspect on lowland river flood plains. Quantification of deposition often proceeds through modelling. However, raster-based sedimentation models in particular suffer from numerical dispersion in the sediment-transfer routine. To simulate conveyance of sediments over flood plains without introducing numerical dispersion, we developed a sediment-transfer model in which we implemented the particle tracking method “Method of Characteristics”. This raster-based model uses input data such as initial concentrations, water levels, flow velocities and dispersion coefficients. In the future, we will use this model as part of a flood plain sedimentation model.
