Erosive velocity in a channel
WebGradient is the slope or steepness of a stream channel. It affects the stream's velocity because the steeper the gradient is, the greater the velocity, due to gravity. Explain how stream discharge and gradient affect the erosive ability of a river Discharge is the volume of water flowing past a certain point in a given unit of time. Weba channel (adapted from Julien (1995)). Critical Velocity Figure 1 shows that both the lift and the drag force are directly related to the velocity squared. Thus, small changes in the velocity could result in large changes in these forces. The permissible velocity is defined as the maximum velocity of the channel that will not

WebThe slope of the channel should be sufficient to generate an adequate runoff velocity to create good positive drainage. Care must be taken not to exceed velocities that will erode the diversion channel (Figure 2-7). Care must be exercised when using diversions above steep slopes; a slide could occur (Figure 2-8). WebOpen Channel Conveyance Criteria. The peak velocity for the 2 year storm must be non-erosive. Consult Soil and Water Conservation Engineering (Schwab et al.) for data on …
