Abstract: |
Prediction of turbidity due to fine grained bed material load under wave action is critical to any assessment of anthropogenic impact on the coastal or lacustrine environment. Waves tend to loosen the mud deposit and generate steep suspension concentration gradients, such that the sediment load near the bottom is typically orders higher than that near the surface. In a physically realistic but simplified manner, a vertical sediment transport model was used to simulate prototype trends in the evolution of fine sediment concentration profiles and corresponding erodible bed depth under progressive, non-breaking wave action. field data collection and laboratory experiments were carried out with Lake Okeechobee bottom sediment to determine the characteristic parameters related tot he fine sediment erodibility under waves. these measured parameters served as input data for the transport model. Prior field observations support the simulated trends, which reveal the genesis of near-bed high concentration fluidized mud layer coupled with relatively low surficial concentrations. It is recognized that estimation of the depth of bottom erosion requires an understanding of mud dynamics and competent in situ sediment concentration profiling. Measurement of sediment concentration in the upper water column alone, without regard to the near bed zone, can lead to an order of magnitude underestimation of the erodible bed depth. |
