The stability of granular material in air is first examined … WebNov 1, 2024 · The incipient motion condition is the hydrodynamic condition, i.e., of velocity and flow depth, whereby the particles lying on a streambed start to move under the action of fluid. But this condition also depends on the particle properties, such as size, density, shape, as well as on the position of each particle with respect to the surrounding ...
WebEFFECTS OF THE FLOW CONDITIONS’ SELECTION ON FLOW DEPTHS The general trend of variation between the depths recorded under all the three flow conditions (M, M1, and M2), for the five bed sediment sizes used, is evident from the bar chart heights and trend lines as depicted in Figs. 2-6. According to that the depths recorded under the M condition
