Flooding is described as the overflow of water, that is contributed to by heavy rains, rivers breaking their banks or raising sea levels. This results in submerging of the dry land by waters and has an effect of causing damages to properties and risking the lives of the populace. The phenomenon happens in places with low elevation, estimated to be of lows of 10 meters, and those that have poor drainage systems. According to the International Disaster Database, about 180 billion people were displaced by floods in the year 2018, and an equivalent loss of properties worth $45 billion. The cost of recovery from floods is considerably high and drains the economy significantly. The following paragraphs will discuss some of the countries that are profoundly affected.
Most of the cities are built on the alluvial plains, that are highly susceptible to the action of moving waters. About two-thirds of this country is prone to flooding, and the most affected areas are the towns. With a high population living in urban settings, it exposes them to the negative effects of floods, which makes it a point of concern for the government. The figures indicate that 23% of the state is low-lying with a total population of 49%, residing in those places. Such, the country has experienced a series of floods among them being St. Elizabeth’s Floods and North Sea Floods. Since the enormous flood of the years 1953, the government has tried to mitigate similar incidences by actions such as the Delta Works program.
With a population of 37,800 people, it has been pinpointed as a country with a high risk of flooding. The highest place is Patio Palace which is 164M above the sea level, while the lowest point in the Mediterranean Sea. 22% of the country is on low scale and is estimated to be below 5M. Most of the citizens residing in these places, are therefore exposed to the effects of rising sea levels. The government has dug dikes to prevent the havoc caused by floods.
The population of China is hitting 1.4 billion people, which is the major contributor to the coastal flooding. This has been the case due to increased emission of greenhouse gases, as a result of anthropogenic activities such as industrialization and increased use of automobiles. The consequence has been climate change, which results in raising of sea levels. It is estimated that about 50 million people in China, will face the adverse effects of flooding before the end of the century if emissions of dangerous gases are not curtailed.
The country suffers from flash floods that destroy the houses and sometimes causes deaths. The major towns that are affected are Isa and Manama. The primary cause is that the state has a lower elevation of 5M above the sea level, and about 24% of the population lives in such areas. The measures that have been adopted to control the floods are relocating people to higher grounds and construction of dikes.
Other countries that are at high risk of flooding are Belgium, Hong Kong, Macao, Barbuda, Gibraltar, and Cayman Island. Most of their population resides in the low-lying altitudes, which exposes them to more risks. Appropriate measures should be taken by the respective governments to find a long-lasting solution to this menace.
