| 摘 要： | I. INTRODUCTIONPrediction of mud bed erosion by forcing due to tidal currents usually requires a numerical solution of the advection--dispersion equation for sediment mass transport. Key role is of course played inthis by the bottom boundary conditions defining erosion and deposition fluxes. The issue of erosion isbriefly considered here. noting that it is customary to calculate the rate of erosion as a function of thebed shear stress in excess of the erosion shear strength of the bed (Me…

| Abstract: | An experiment is described to simulate fluid mud entrainment by current shear. A recirculating flume with a disk pump system to prepuce shear was used for this purpose. Significant interfaclal instabilities were observed with resultant fluid mud entrainment. An empirical relationship is obtained between the non- dimensional buoyancy flux and the mchardson number, which is then compared with that obtained for salt-stratified flows. This comparison makes apparent the additional dissipation of turbulent kinetic energy in sediment-water systems relative to salt-stratified systems. particularly at higher Richardson numbers as the entrainment rate decreases substantially. |
