During the SQd 3, the Liaodong Bay Depression once again went through slip-rifting, with the lake level rising rapidly. Meanwhile, the incised canyons provided a channel for the deposition of the braided river delta front to enter the Liaoxi uplift and slope.
River incision is the natural process by which a river cuts downward into its bed, deepening the active channel. Though it is a natural process, it can be accelerated rapidly by human factors including land use changes such as timber harvest, mining, agriculture, and road and dam construction.
