Sediment Parameters Sample Clauses

Sediment Parameters. For simulating sediment impacts the following general parameters were used: • Settling velocity – 0.5 mm s-1 • Critical shear stress for deposition – 0.2 N m-2 • Critical shear stress for erosion – 0.3 N m-2 • Minimum depth where deposition allowed – 0.1 m • Resuspension rate – 30 g m-2 d-1 • Wave calculation method – ▇▇▇▇▇▇▇▇ • Chezy calculation method – White/Colebrook • Bottom roughness – 0.001 m (1) • Fetch for wave driven erosion – 2000 m The above parameters have been used to simulate the impacts from sediment plumes in Hong Kong associated with uncontaminated mud disposal into the Brothers MBA (2) and dredging for the Permanent Aviation Fuel Facility at Sha ▇▇▇▇ (3). The critical shear stress values for erosion and deposition were determined by laboratory testing of a large sample of marine mud from Hong Kong as part of the original WAHMO studies associated with the new airport at Chek Lap Kok.
