Yellow River Delta Tidal Flat Shrinking Rapidly Due to Changing Coastline.
The Yellow River delta has seen changes in its coastline and tidal flat over the years. Using satellite images and depth data, researchers found that the coastline moved in some areas and stayed stable in others. After the river changed course in 1976, the tidal flat grew quickly, but later decreased due to human activities. Another river course change in 1996 led to more changes in the tidal flat, with some areas growing and others eroding. Overall, the tidal flat of the Yellow River has been shrinking since 1996.
