Geomorphological Effect of Discharge Reduction on the Lower Reaches of the Yellow River

Based on the study the relationship of the erosion/deposition in the lower reaches of the Yellow River and the variation of river discharge, it is concluded that the decrease of the discharge can induce the deposition in the river channel, and sedimentary reduction even retreat of the river mouth. The reduction of sand supply of the Yellow River also can induce erosion along the coasts of the Yellow River delta and retreat of the delta.
