A sudden flood of great volume, usually caused by a heavy rain Also, a flood that crests in a short length of time and is often characterized by high velocity flows
A flood which is caused by heavy or excessive rainfall in a short period of time, generally under 6 hours, leading to water that rises and falls quite rapidly The term may also be used to alert the public of non life threatening flooding of small streams, streets, storm drains, and low lying urban areas A flash flood can also be caused by the failure of a dam or from ice jams on waterways
A flood which is caused by heavy or excessive rainfall in a short period of time, generally under six (6) hours, leading to water that rises and falls quite rapidly The term may also be used to alert the public of non life threatening flooding of small streams, streets, storm drains, and low lying urban areas A flash flood can also be caused by the failure of a dam or from ice jams on waterways
A flood that rises and falls quite rapidly with little or no advance warning, usually as the result of intense rainfall over a relatively small area Flash floods can be caused by situations such as a sudden excessive rainfall, the failure of a dam, or the thaw of an ice jam
The result of heavy or excessive amounts of rainfall within a short period of time, usually less than 6 hours, causing water to rise and fall quite rapidly
A flood which occurs suddenly and without warning Flash floods are common after torrential mountain thunderstorms They affect mountain valleys because there is little soil to soak up the rain and so it quickly rushes to rivers
Heavy rainfall and localised flooding of short duration with a relatively high peak discharge Often caused by severe thunderstorms or intense rainfall events such as an East Coast Low For severe thunderstorms, a flash flood event is considered to be a 1 in 10 year rainfall event
flood of water in a normally arid area brought on by a sud- den downpour of rain flint compact, hard, brittle mineral, commonly grey in colour, found in nodules in chalk deposits flooding the inundation of land that is not normally covered with water fluvioglaclal of a process or landform, associated with glacial meltwater Meltwater, flowing beneath or ahead of a glacier, is capable of transporting rocky material and creating a variety of landscape features, including eskers, kames, and outwash plains
A flood which is caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours Also, at times a dam failure can cause a flash flood, depending on the type of dam and time period during which the break occurs
Follows a situation in which rainfall is so intense and severe and runoff so rapid that it precludes recording and relating it to stream stages and other information in time to forecast a flood condition (FEMA definition) See also flood
A faster, more dangerous flow of water that results from tropical storms, dam failures, or excessive rain and snow; the flooding of an area that occurs in a matter of hours
