Floods come from overflowing flooded rivers, lakes or reservoirs caused by heavy rainfall (not necessarily where the flood occurs, especially upstream in the case of a river). Be directly created by a very heavy rain. Finally, more rarely, breaking a dyke or dam can cause flooding.
A violent rain can quickly produce torrents in dried-out creek beds, or create a wave that rushes into a rectilinear place, like a street, causing a real wall of water that sweeps everything in its path.
If severe rain or thunderstorms occur for a long time after a period of drought, move away from risky streams and flood-prone areas. This does not mean that you will necessarily be safe: flooding can cover a very large area. It is of course advisable to settle in height. If the water rises, try to reach the highest possible point where you will be safe. In mountainous areas, in case of heavy precipitation, avoid streams at the bottom of the valleys, which collect all the precipitation from the surrounding mountains and sometimes start to overflow very quickly.

A priori food is not a problem in case of flood, because animals also tend to take refuge on the heights. Animals, both prey and predators tend to help each other out of the water. Beware, however, of herds of animals, which may panic and become dangerous.
Drinking water may be difficult to access because the water around you will probably be contaminated by all sorts of things. Get rainwater if you have nothing to drink, and for water from elsewhere, always boil it before consuming it.
Surviving a flood in a building
If you are in a building at the beginning of the flood and the water rises quickly, stay there. You will be safer than if you are trying to escape on foot. Turn off gas and electricity and prepare something to eat for a while, warm clothes, drinking water in tightly closed bottles. It is very important to keep your water reserves tight to prevent accidental wastage or contamination. If you can, take a torch, a whistle, a mirror, very colorful clothes, or something that can serve as a flag. They can help you report your position to rescue teams. A camping gas can be useful to you to heat your food or water, or simply to warm you. Candles can also be useful. Provided you do not forget to take some light.
Go upstairs, or even on the roof if there is no floor in your building. If you find yourself obliged to go to the roof, try to build a shelter there. If the roof is sloping, hang yourself and all those who are with you to the chimney, or any solid object that protrudes from the roof. If the water continues to rise, try as much as possible to build a rudimentary raft on which you can hang. If you do not have ropes to bind objects together, use sheets, for example.
As long as the threat flood does not destroy your building or cover it, stay in it or on it. Or even on the roof if there is no floor in your building.

Preparing for a flood
If you live in an area at risk for flooding, find out about the elevation of your location from normal water levels and those from previous floods. Determine the easiest route to a high point near you (without necessarily borrowing the highways because they tend to drain flooding into the bottom of valleys.) During the rainy season, keep informed of the flood warnings that will give you Often the expected heights and areas likely to be affected.
Even a few centimeters of water can do a lot of damage and it is worth having the sandbags or, if you do not have plastic bags filled with soil at the bottom of the Doors to prevent as much water from entering your home. If your home is sturdy and you securely lock doors and windows, water will not enter at all. Also consider blocking the ventilation and any spaces where water may seep in.
If a heavy flood is expected, there is no point in trying to prevent your cellar from being flooded. On the contrary, it can cause additional damage due to the pressure of the water outside the walls of your basement. If you are sure you are flooded, you could even fill your cellar with clean water to equalize the pressure between the outside and inside. You will also have less trouble cleaning up at the end of the flood.

Clear out
If you abandon your home, think of getting inside all your furniture and other outdoor items. This will reduce the amount of debris carried by the flood.
When you are on your way, remember that a slight slope on a road can quickly lead to a depth of water that can not be crossed.
Never try to cross a flooded area if you are not absolutely sure that the water will not exceed half of your car wheels or your knees. If you have to cross, use the fording techniques.
If you are crossing a partially flooded bridge be particularly careful: you may not be able to see if parts of the bridge have been swept away by the current.
Flash floods
In case of violent and sudden precipitation, move away from the bottom of valleys and beds of rivers, during and after the rain. It is not only at the bottom of the valleys that you can be in danger: waves can flow along the hills or mountains, creating a tidal wave carrying away deadly debris with it.
Coastal flooding
They are often a combination of high waves and wind that makes them even higher. You will generally be alerted and in this case it is better to evacuate.
The results
When the water has receded, it will leave behind desolate scenes full of debris and possibly victims. The dead animals will begin to rot and contribute to pollution. Be especially careful with hygiene. Burn the corpses of animals, and boil the water before drinking. Some agricultural crops resist flooding, as well as birds that have escaped from the water.
If you are isolated and have no other source of food, you should be able to find some using hunting and gathering techniques.
