Hilly flank

From Wikipedia, the free encyclopedia

A hilly flank is a subtropical woodland zone that flanks or borders a river.

An example of a historically important hilly flank is an area between two rivers, such as the Tigris and Euphrates in the Middle East. This area, Mesopotamia, was the location of one of the world’s first civilizations, and was the origin of the idea of irrigation. The people of this early civilization found it easy to divert water and form man-made rivers for irrigation, trade, and travel.
