gradient

Its largest tributary, North Caney Creek, has a gradient of 15.5 feet per mile.

At five and a half miles the brow of the main rise was reached, and the gradient became much flatter beyond it.

Both sledges ran easily for nearly a mile over neve, when the gradient increased to one in ten, forcing us to relay.

This ridge had a gradient of one in ten, and, unfortunately, also sloped down towards one of the open crevasses.

This is really the driving wheel by which it slowly moves up the steep gradient.
