In this paper, we propose a different way of examining landscape organization by introducing the "river corridor width" (lateral distance from the centerline of the river to the left and right valley walls at a fixed height above the water surface) as one moves downstream.
But pollution-chewing microbes have already been introduced into the river.
Experimental geomorphology was initiated by G.K. Gilbert, who introduced the notion of graded rivers (a concept also deployed by Davis).
