Influences of water and sand regulation on Yellow River estuary reach monitored by remote sensing

Regulation of water and sand is a unique important measure for the Yellow River,and remote sensing monitoring is a significant method to monitor the effect.Based on the analyses of remote sensing data of three tests of regulation of water and sand,siltation and erosion of the Yellow River estuary reach are quantitatively described.The relationship between the siltation and erosion of the Yellow River estuary and coming water and sediment is found by using the measured data of Lijing Hydrologic Station in the Yellow River.It can be seen that the regulation of water and sand plays an active role in the improvement of the Yellow River estuary reach.
