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.)
Floodplains link rivers, wetlands, and lakes and are an important part in keeping all of these ecosystems functioning. In order for floodplains to function properly, they need to flood occasionally. Cutting floodplains off from rivers and lakes by levees can be destructive for the river and the floodplain.
