Biostabilization of cohesive sediment beds in a freshwater wave‐dominated environment

An assessment of bed sediment stability was carried out over biostabilized and nonbiostabilized cohesive sediment within a laboratory wave flume. Biofilms of 5, 9, and 15 d were grown over kaolinite, and changes in bed shear stress were applied through increasing wave height. Results show that the stability of the bed was highly related to the structural integrity of the overlying and integrated biofilm. Biofilms with substantial algal growth …
