Hilly Flanks
A hilly flank is a subtropical woodland zone that flanks or borders a river.
An example of hilly flanks is an area between two rivers, the Tigris river and the Euphrates river. So, this area housed the world’s first civilization, Mesopotamia, and also started the idea of irrigation. The people in this early civilization were surrounded water from the rivers, so it was easy to divert water and form "man-made" rivers for trade and irrigation. Eventually these man-made rivers connected the two rivers which helped with trade and travel. This area is known for its sufficient rainfall which leads to the over abundance of wild wheat and barley. Peoples in this area also started the first signs of domesticating animal and plant life. Animals like pigs, sheep, and goats were all wild and were domesticated for human help.
