Tip 2: How to prevent flooding
Flood - natural disaster, which could lead to significant loss of life and extensive material damage.The sad irony is that the misfortune of man brings water, vital to him.From time immemorial people settled on the banks of reservoirs.But if the water level will rise suddenly and sharply, for example, because of heavy rains, strong winds, tides, etc., it can turn into a dangerous enemy.
Of course, you can not argue with the elements.But at reasonable precautions taken in advance can minimize the damage, and most importantly - save lives.For example, in places that are prone to frequent and severe flooding, it is necessary to build protective walls (dams).It was rescued from the dam flooded the whole country - the Netherlands, a large part of whose territory lies below sea level.The second largest city of Russia - Saint Petersburg - often suffered from devastating floods.After the construction of the dam spanning the Neva Bay, this risk was reduced to a minimum.
In many parts of the coast of Japan, subject to shocks tsunami waves, also built dams.If the wave height is not too large, they successfully resist their onslaught.But, of course, with especially strong tsunami (in March 2011), even they will not help.
huge role in preventing floods on the rivers play a system of dams and reservoirs.For example, during heavy and prolonged rains, especially in the highlands, where the water, without having to soak into the ground, flows on the slopes, the river can quickly spill, causing flooding.If the channel of the river dammed, flooding can be prevented.Firstly, in most cases, before the dam when there is a natural reservoir, which can take a large amount of additional water.Secondly, even if the level of the reservoir will rise to alarming limits, the excess water can be reset through the same dam by opening the valve.Of course, dams and reservoirs, can not give a 100% guarantee to prevent flooding.But their risk of repeatedly reduced.
simple and effective, although time consuming way - the construction of protective trees along the banks of the river.As a rule, they are made of sandbags, if the water level rises alarmingly.These works, in case of necessity, involve not only the rescuers, but also the military, law enforcement, volunteers from the civilian population.Shafts are building in those places, which primarily threatens flooding.
