Abstract

The impact of the turbulent flow and the algal growth in eutrophic waters on settling velocity spectra of suspended sediments is quantified using mathematically derived critical suspension parameters of equilibrium stages. The continuous character of the particle density is considered as well as retardation effects at the river bed. 1 Introduction The seasonal development of the suspended sediment concentration in eutrophic river sections essentially depends on algal growth and sedimentation processes. River discharge, water temperature, light intensity and dissolved nutrients are the determining parameters which influence these processes. In the Spree River, a highly eutrophic lo
