Impact on Discharge Capacity by Sediment-Runoff Regulation in downstream of the Yellow River

Since 2002,the sediment-runoff regulation of Yellow River has persisted in 7 years,the flow capacity of the main channel has been greatly enhanced through erosion. Through the analysis on the measured hydrological data,the water and sediment regulation,the function of sediment-runoff regulation has been demonstrated.Under the non-saturation condition,the flooding discharse has created a strong effect of the erosion and deposition in the lower reaches of the Yellow River,increasing the discharge capacity,reducing the river bed elevation,and alleviating the trend by silting up year by year in downstream of Yellow River.
