Flash floods

Flash flooding are very fast events; they are caused by extreme rainfall events or a sudden release of water in a short period of time. All occur within minutes or hours after a heavy rain event. Large torrents of water are created and they move at great speed. The great part of this type of flood is caused by heavy rainfalls, which falls in a very short period of time. Another way in which flash flooding can occur is by a sudden release of water from a levee or a sudden release of a debris or ice dam upstream and also by a damage to a dam. The danger of a flash flooding is very high and lies in the fact that this type of event brings with it all the debris that it finds on its way. It’s very dangerous and destructive also because of the force of the water. It is therefore necessary to try to understand the process of these floods and where they occur so as to reduce all associated risks and costs (Four Common Types of Flood Explained, s. d.).
