Abstract |
The 'hypolimnetic flow' is a two-layered flow with the upper layer stagnant. The report presents the possibility of different flow regimes for the hypolimnetic flow which may be determined from the parameters of slope of channel bottom, flow depth, flowrate, density difference of water in the two layers, and channel roughness. The analysis is limited to the steady-state case of the hypolimnetic flow and the 'upper layer analysis' in which the lower layer is stagnant. Interfacial profile equations which predict possible existence of ten different flow regimes for the hypolimnetic flow and two regimes for the upper layer analysis were obtained from the equations of continuity and momentum for two-layered flow. |
