We know little regarding the processes that govern the evolution of suspended particle characteristics during their transport through a river basin. Up to now, no measurement method allows measuring continuously the suspended sediment properties in highly concentrated fluid flows, such as those observed in headwater catchments during runoff events or near bed in muddy estuaries. The Aggregate and Floc Characterization System (SCAF) has been developed in order to measure suspended sediment properties for a wide range of concentrations. It has been designed to be easily incorporated into automatic water samplers.
