Effect of Biofilm Cohesiveness on Sediment Deposition in the Channel with Vegetation.
Synopsis of project aims:
Develop methods to grow biofilm on plexiglass plates that can be transported to experiment channel.
Run experiments to measure deposition rate over bed sections with and without biofilm and under different channel velocity and different density of model vegetation, consisting of an array of PVC cylinders.
Develop method to efficiently decontaminate the water in the experiment channel after each experiment.
Analyze the impact of vegetation-generated turbulence on the sediment deposition over the biofilm-coated bed.
Develop an integrated sediment transport model to represent erosion and deposition processes in the vegetated channel.
