Summary:Since the measurements of bulk property parameters of cohesive sediments can be done easily, it is useful to relate the critical shear stress of cohesive sediments to some of these parameters. In this paper, data from two experiments are reanalysed and the dependence of the critical shear stress on bulk density, clay solid content and clay volume content is highlighted. The results from Sharif demonstrate the critical shear stress as a function of bulk density and clay solid content, while that from Kothyari and Jain indicate that the critical shear stress depends on both the clay solid content and clay volume content of cohesive sediments in the presence of gravel and air. Moreover, it is concluded a critical clay solid content exists around 18%, beyond which the critical shear stress increases rapidly with the increase of bulk density.
