520 | 3 |a"Some of the earlier studies on formation of meanders suggest that the turbulence-driven secondary currents that are present in a straight channel with non-circular flow geometry may be responsible for the development of meanders in natural streams. The present study was undertaken to test this hypothesis. Laboratory experiments in mobile boundary channels with glycerine as a flowing medium showed that meanders do form in laminar flows. Since laminar flows are free from such secondary currents it becomes evident from this study that the presence of turbulence is not a necessary condition for the formation of meanders. Therefore, attention should be directed to other mechanisms such as fluvial instability for the explanation of meander formation"--Abstract, page 2. |
