1 Hamartia: Many people who discuss tragedy often mention the hero's 'fatal' or 'tragic flaw.' However, Aristotle would never accuse a hero of such a personal defect. 2  Instead, he asserted that they were guilty of hamartia, or missing the mark.
Floodplains are landscapes shaped by running water. As streams and their larger forms, rivers, flow across the surface of land, they transport eroded rock and other material. (Erosion is the gradual wearing away of Earth surfaces through the action of wind and water.)
There are two main types of riverine flooding: 1  Overbank flooding occurs when water rises overflows over the edges of a river or stream. 2  Flash flooding is characterized by an intense, high velocity torrent of water that occurs in an existing river channel with little to no notice.
