River Meanders in Eberswalde Delta

November 21, 2007

Eberswalde Delta contains river meanders, which indicate that flowing water was present for an extended period of time, not just the weeks required to explain the catastrophic flood channels.

The former river channels are high rather than low, which is called inverted relief. Coarse gravel was deposited in the stream channel, which later proved more resistant to erosion than the materials outside the channel, creating this inverted relief.

Meanders are formed when a river channel gradually erodes the outer banks, increasing the curvature of the channel. Eventually the river decides to take a short cut, cutting off a meander, as shown here. This produces what are called oxbow lakes.
