This figure is a plot of soil loss values for different slope shapes.
The average steepness is the same for three slope shapes.
Values less than zero for the concave shape are deposition.
Note that maximum erosion rate on the concave slope is about the same for both the uniform and concave slope although sediment yield from the concave slope is much less than sediment yield from the uniform slope.
Note that maximum erosion rate for the uniform and convex slope occurs at the end of the slope.
Maximum erosion rate on the convex slope is much higher than maximum erosion rate on either the uniform or concave slopes.
