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.)
Flash flooding occurs when it rains rapidly on saturated soil or dry soil that has poor absorption ability. The runoff collects in gullies and streams and, as they join to form larger volumes, often forms a fast flowing front of water and debris.
