Mapping China's Changing Coastline

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

Mapbox has used satellite imagery from NASA together with USGS’s Landsat plan to dramatically visualize this alter inwards the Yellow River Delta since 1979. The map shows how the Delta has grown together with shrunk over the final 16 years.

In 1996 the original channel into the body of body of water was blocked yesteryear Chinese engineers, forcing the river to the northeast. In the get-go images of Mapbox's China's Changing Coastline map the tip of the delta, at the halt of the quondam channel, has retreated from erosion of the silt deposits. If you lot press play on the map you lot tin run into 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 cavity of the novel channel.
