Floods can be caused by river spills due to heavy rains, not necessarily at the place where the flood occurred, a rise in sea or lake levels due to underwater earthquakes, hurricanes and bizarre tides or winds, or the destruction of a dam or dam.
Floods, normal and tidal, flood preparedness, evacuation and flood consequences, flash flood.
Heavy rains quickly form water flows in dry river beds, raise the water level in narrow channels or behind some kind of obstacle that suddenly gives way, and the wall of water covers everything in its path. Rains that persist for a long time after the dry period, and heavy storms should tell you to stay away from the channels of water flows and low terrain, but floods can capture a much wider area.
, a whistle, a mirror, bright clothes or flags, which will be useful for signaling, and add all this to your inventory. A camping site will be needed to warm food and drink, as well as for heat. Candles come in handy too and don’t forget the matches.
Go to the top floor or to the roof if it is a one-story building. If you are forced to get out on the roof, make some kind of shelter. If the roof is sloping, attach everything to a chimney or other solid structure that should support you. If it looks like the water continues to rise, prepare something like a raft. If there are no ropes to tie it, use sheets, etc. Stay in place until the water begins to subside, unless it threatens to flush the building or rises so high that it forces you to evacuate.
If you live in a river valley or in a flood-prone coastal area, find out how high you are above normal water levels. Find the easiest road to higher areas not necessarily on the highway, as large roads pass through drainage channels at the bottom of the valleys. In rainy periods, listen to forecasts of upcoming floods that often predict estimated water level rise and estimated areas.
Even a few centimeters of water level rise during flooding can lead to dire consequences, and it is worthwhile to put sandbags or plastic store bags with the ground at the base of doors and windows to hold as much water as possible. If the building is really solid and the doors, windows, and other openings are blocked, water will not enter. The central combustion channel, ventilation and other openings must be closed.
If a large rise in water is likely, then there is not much point in trying not to let water into the basement. In this case, in fact, in some houses with basements, this can lead to additional damage due to the difference in pressure on the walls of the basement. If you have to be flooded, then consider filling the basement with clean water to even out this pressure. Then you have to rake less dirt and debris.
Flood threat evacuation.
If you are leaving your home, bring street furniture and other moving objects inside. This will reduce the amount of floating debris and overall damage. When moving or moving to a safer place, remember that a slight downward slope can make a big difference in depth. Do not try to cross a puddle (or water stream) unless you are absolutely sure that the depth is not higher than the middle of the car wheel or your knee. If you are forced to cross a water barrier, use the river crossing technique. When using a bridge covered with water, be extremely careful. You may not see that the stream destroyed part of the bridge..
During sudden rainstorms, avoid the bottom of valleys and dry riverbeds both during and after rain. Remember you don’t like to be caught in a shaft of water, often with mud and deadly debris torn out by trees and stones..
Usually they are the result of a combination of a high tide with a strong wind that makes the tide even higher. As a rule, a tide warning, flood warning, etc., and the best way to rescue evacuation are given..
After the water leaves, a picture of devastation and destruction remains, strewn with debris and corpses of flood victims. Rotting and contamination of water pose a risk of the spread of disease, and additional precautions must be taken. Burn animal bodies do not risk eating them and boil all the water well before using it. Some surviving plants may remain. It is safe to eat birds surviving during the flood.
