Mapping China's Changing Coastline


In Red People's Republic of China the Yellow River carries 1.4 billion tons of silt to the Bohai Sea every year. One lawsuit of all this silt is that the Yellow River Delta continually grows in addition to shrinks over time.

Mapbox has used satellite imagery from NASA in addition to USGS’s Landsat programme to dramatically visualize this modify inward the Yellow River Delta since 1979. The map shows how the Delta has grown in addition to shrunk over the final 16 years.

In 1996 the primary channel into the bounding main was blocked past times Chinese engineers, forcing the river to the northeast. In the starting fourth dimension images of Mapbox's China's Changing Coastline map the tip of the delta, at the halt of the onetime channel, has retreated from erosion of the silt deposits. If y'all press play on the map y'all tin plough over the sack encounter how a novel Yellow River Delta grows out from the novel channel of the Yellow River equally billions of tons of silt are deposited from the river at the oral fissure of the novel channel.
