| 中文摘要: |
| On the basis of the study of initial sedimentation of suspended participates discharged from a continuous point source, the mode of dispersion, descension and deposition of the suspended particulates which are released from a line source is derived. By use of puff model, the semi-analytical solution to the problem of initial sedimentation of suspended particulates discharged from a continuous line source in one-dimensional homogenous current fields, of which water depth is constant, is presented, some computations and analyses for long-term distribution of sedimentation are carried out under various sets of parameters. And the comparisons between the sedimentation results of the line and point source are conducted. The results show that the higher the initial height,and the smaller the fall velocity of the particles,the closer the sedimentation distribution results of the line source to that of the point source. |
