Abstract

In a laboratory flume the formation and erosion of stratified sand-mud beds in uniform flow was studied. The experiments showed that depending on the initial conditions of suspended sediment concentration and mixture composition, consecutive inputs of a mud/sand suspension will lead to the formation of a layered sediment bed. Peaks in the measured density profiles show the different layers and indicate a possible segregation of the sand due to differential settling. During the erosion of the stratified bed, the sediments are eroded layer by layer. This results in a sequence of suspended load (fines) and bed load (sand) transport phases.
