Abstract

A depth - averaged model for simulating transport and sedimentation is intro- duced which allows to take into account the dynamic behaviour of the mean particle settling velocity of suspended particulate matter (SPM) in case of sedi- mentation processes on river reaches. The model calculates the varying parame- ters of the particle settling velocity distribution and the mass concentration of settling velocity fractions dependent on time and river location. 1 Introduction Suspended particulate matter plays an important role in spreading and exposition of nutrients and pollutants in natural rivers. As the sorbed pollutants usually ap- pear only on preferred particle fractions, the distribution of s
