Study on Distribution Characteristics of Suspended Sediment in Yellow River Estuary Based on Remote Sensing

In this paper, we used the MODIS L1B remote sensing images of March, June, September and December in 2006-2011 which were selected. The distribution characteristics of suspended sediment in the Yellow River estuary were analyzed by combining the cross-calibrated multi-platform wind data of the same period. From the spatial distribution, there are mainly three high concentration suspended sediment areas near the Yellow River estuary and the concentration of suspended sediment near the shore is greater than that in the deep sea. From the seasonal distribution, the content of suspended sediment in spring and winter is higher than that in summer and autumn. The region of high suspended sediment is least in summer. The suspended sediment concentration is higher in the southern area than in the northern area, and the near-shore water is higher than that in the deep sea. The results show that local wind field has a certain influence on the distribution of suspended sediment and the correlation coefficient is 0.38.
