Biofilm, a product of metabolic activity, has an important effect on the physico-chemical properties of cohesive sediment. However, little effort has been made to determine the substantial effects of biofilm growth on specific sediment properties, for example rheological properties. Understanding the changes associated with biofilm growth and quantifying the time scales over which these changes occur are important for understanding how biofilms mediate sediment properties and processes and the development of sediment transport mechanics. The effect of biofilm on the rheological properties of cohesive sediment was investigated experimentally. The rheological properties of sediment slurries with and without biofilm at different growth phases were measured and compared. Measurement showed biofilm growth has a significant effect on the rheological properties of cohesive sediment. Rheological equations for biofilm sediment and expressions for rheological properties which change over time are proposed. These equations, and information on biofilm sediment, are important for inclusion of biosedimentological processes in models of sediment dynamics.
