Kennedy's silt theory 2. Lacey's silt theory. 6.4.1 Kennedy's Theory Gerard Kennedy, from his observation concluded that the silt supporting power in a channel cross-section is mainly dependent up on the generation of eddies from the bottom width of the channel section, rising to the surface. See Fig 2.

WebHence according to Lacey’s conception regime conditions may be subdivided as initial and final. Lacey also states that, the silt is kept in suspension solely by the force of eddies. But Lacey adds that eddies are not only generated on the bed but at all points on wetted perimeter. The force of eddies may be taken normal to the sides, Fig. 7.2.
