Abstract
Changes of water and suspended sediment composition during three single flood events were investigated in two small catchments in the Mosel region. In addition to suspended sediment characteristics (turbidity, loss on ignition, density, chlorophyll content), several different nutrients and heavy metals were determined in the dissolved and particulate phase. The flood events investigated were characterized by a single peaked hydrograph. In contrast suspended sediment concentrations and the other parameters showed more complex behaviour. The transport of suspended sediment was not only controlled by discharge magnitude. In the course of a flood event different suspended sediment sources are activated. Using the chemograph and the timing of samples collected during the hydrograph these suspended sediment sources can be identified. In addition to the remobilization of sediment and channel erosion, inputs of suspended solids from a sewage plant, road discharge, topsoil and interflow could be identified.
