| Abstract: | A new method has been proposed for simulating the development of a channel on sloping surface of an agrolandscape by the point source method. To study the direction and rate of channel development by the slope flow, it is proposed to take into consideration both the flow parameters and the gradient of erosion resistance potential, which represents the water flow energy necessary for the erosion of unit soil mass and its removal from the zone of its natural occurrence. The approach used makes it possible to restore the general situation from the experimental data. The proposed theoretical premises about the effect of the surface shape and state on the channel development have been confirmed by laboratory studies. From the results of these studies, a relationship of the channel development direction with the erosion resistance potential and the flow velocity has been derived. |
