Abstract
Presented in this study are experimentally measured characteristics of the entrainment rate and settling speeds of fine-grained, cohesive sediments in freshwater. The investigation focused on three different sediments of varying mineral composition which are representative of the sediments of Lake Erie. The influences of the bulk sediment water content and of the mineral and size composition of the entrainment rate and equilibrium concentration of these suspended sediments were determined. Linear increases in the bulk sediment water content resulted in logarithmic increases in the entrainment rate and equilibrium concentration. For a limited range of shear stresses near that needed to initiate noticeable entrainment the entrainment rate and equilibrium concentration increased logarithmically as the applied shear stress was increased linearly. For larger stresses, linear increases in the applied shear stress caused approximately linear increases in the entrainment rate and equilibrium concentration.
