Flooding is a sharp increase in the water level inriver or other body of water. Regardless of the reasons for the occurrence (there may be several), the phenomenon differs from the flood by its short duration and suddenness. That is, when a river or a lake after a rain or a sharp thaw of snow comes out of the coast, this is a flood. The meaning of the word rather accurately determines the essence of the process.
Possible causes of floods
If we consider the events precedingThis phenomenon and become its main cause, there may be several. Firstly, a long pouring rain, as a result of which the reservoirs leave the shores. The period of high water after intense precipitation is usually very short and lasts for several hours. However, due to its rapidity, even such a short-lived phenomenon can cause serious damage. In case of a repeated shower in the same territory, there are sometimes multi-peak floods. This event is characterized by a periodic flood of reservoirs with the flooding of nearby territories.
What is flood, people know very wellsettlements near the mouths of large rivers. The flood often comes with warming and is the result of the rapid melting of ice and snow. This kind of flood continues long enough, but it is easier to predict than the one that occurs after the rain.
Consequences of the phenomenon
The main danger of flood in itsunpredictability. Meteorologists can predict precipitation, but their calculations are not always correct, and the rain intensity is not so easy to find out in advance. As a result of the spill of large rivers, a rapid flow arises, capable of destroying houses and other structures, bridges, and washing away machinery. Such a wave can damage agriculture, drown animals and wash crops off the fields.
Unfortunately, residents of settlements,located in the lowlands and near the high-water rivers, know perfectly well what the flood is, and try to prepare for it in advance. However, this is possible only if the cause is not rain, but the melting of ice and snow.
Fighting the consequences
Since this event rarely leadsto global financial losses, the problems arising as a result of such elements are solved at the local level. Undoubtedly, people who survived this disaster and learned from their own experience what the flood is, will agree with the need for emergency rescue operations at the place of its occurrence. But if there are no victims among the population, their lives and health are not threatened, the consequences are eliminated on their own. In the event that significant damage is caused to buildings and property, the state pays compensation. To avoid a repeated flood, dams and other coastline fortifications are being built.
To people who survived the flooding of the river with floodinghousing, no longer remembered what is flood, after the elimination of its consequences, it is necessary to conduct a number of activities aimed at preventing such in the future.
First of all it is necessary to analyze possiblecauses of the event, to understand the mechanism of its occurrence. In some cases, it makes sense to move buildings and other objects located in lowlands to other, more protected places. Also, with the construction of new bridges, the construction of roads, other structures should take into account the possibility of high water. To assess the danger of this phenomenon, constant monitoring of the water level is used. When there is a danger of the release of reservoirs from the coast, the early warning system of the population is used.
Flooding - it's short-term, but prettyan unpleasant phenomenon. It is expressed in the spillage of rivers and other water bodies as a result of the presence of excessive moisture in them. The best way to deal with floods is to prevent it and the thoughtful activity of a person in low-lying areas and other areas of high risk.
