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.

This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Web5. According to Lacey the grain size of the soil forming the channel is an important factor. He connected the grain size (m r) with his silt factor (f) by equation f = 1.76 √mr. This …
