The estuary. Each year the river discharges
over a billion tons of sediment into the Bohai Bay.
The river delta is being extended steadily at a rate
of 0.5 km per year, adding roughly 40 sq km of land
in the process. The top picture is an aerial view of
the estuary (which is probably in false color,
with color indicating the temperature of the surface).
In actual color it looks like the picture below,
and for a view at sunset.
