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.)
Discuss how a floodplain forms and why people live on floodplains. Floodwater carrier along with it a great amount of sediment roded from Earth's surface and the sides of the stream channel. As the floodwater recedes and its volume and speed decrease, the water drops sediments load onto the stream's floodplain.
