Image Caption: Betsiboka River delta, NW Madagascar
The estuary of the Betsiboka River (left center) has been half filled by sediment brought down from inland by the Betsiboka River (which enters the view bottom left). The sediment appears in this dramatic color-infrared view as a series of elliptical islands which now reach more than half the distance to the mouth of the estuary.

The islands did not exist before WWII, so that the estuary acted as a waterway for oceangoing ships to a now-abandoned port at the original head of the estuary. Heavy deforestation since WWII has probably contributed to the degree of the sedimentation in this estuary.
