When the river overflows its banks, it
carries the
soils from the floodplain and
eroded upland agricultural
soils down - stream creating sand dunes, mud flats, and deltas.»

eroded soil,
carried in rivers like this one, accelerated dramatically in the wake of European forest - clearing and intensive agriculture in North America.
