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.)
Fluvial (River) Flooding Fluvial flooding occurs when rivers burst their banks as a result of sustained or intense rainfall. The image below shows fluvial flood risk for Dublin, created using our Flowrouteâ¢ flood modelling software. Fluvial Flooding Impact: Cornwall. Flowrouteâ¢ is used to predict the depth, duration, velocity and extent of flooding and is highly accurate. The images below compare fluvial flood risk modelled for Lostwithiel in Cornwall against aerial photography of an actual flooding event at that location in 2010. Coastal Flooding. Coastal flooding is caused by extreme tidal conditions including high tides, storm surges and tsunamis.
