Abstract
Sediments form mixtures of non-cohesive and cohesive materials in rivers, reservoirs or sewer systems. Both erosion and transport phenomena will differ completely from those observed in cases of "traditional" non-cohesive sediment transport. The erosion and transport of cohesive sediment mixtures is still not completely understood. Laboratory flume tests with artificial mixtures of non-cohesive and cohesive sediments are presented in this paper. Erosion rates are assessed as a function of the percentage of the cohesive binder. Rheology data are linked with erosive behaviour. The influence of a transient flow situation on the transport capacity is being examined for these mixtures.
