Floods can be slow, or fast rising but generally develop over a period of days. Dam failures are potentially the worst flood events. A dam failure is usually the result of neglect, poor design, or structural damage caused by a major event such as an earthquake. When a dam fails, a gigantic quantity of water is suddenly let loose downstream, destroying anything in its path. Flash floods usually result from intense storms dropping large amounts of rain within a brief period.
Flash floods occur with little or no warning and can reach full peak in only a few minutes.
The media can raise awareness about floods and flash floods by providing important information to the community. Localize the information by printing the phone numbers of local emergency services offices, the American Red Cross, and hospitals. Interview local officials about land use management and building codes in floodplains. Work with local emergency services and American Red Cross officials to prepare special reports for people with mobility impairments on what to do if an evacuation is ordered. Periodically inform your community of local public warning systems.
