Satellite view of river delta changes in China. China's Huang He (Yellow) River is the most sediment-filled river on Earth. Each year, it transports millions of tons of soil from a plateau it crosses to a delta it has built in the Bohai Sea. These images show the delta's growth from 1985 to 2014. The latter image also shows another change: ponds that hold shrimp and other seafood (seen here as dark geometric shapes along the coastline) were built on what were once tidal flats.
