Question

write about flood in 1000 words

Answer 1

A flood is an overflow of water that submerges land that is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water.  In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.

Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rainwater on saturated ground in an areal flood. While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, these changes in size are unlikely to be considered significant unless they flood property or drown domestic animals.

Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While riverine flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry.

Some floods develop slowly, while others such as flash floods, can develop in just a few minutes and without visible signs of rain. Additionally, floods can be local, impacting a neighborhood or community, or very large, affecting entire river basins.

Answer 2

Rapid On-set Floods

These take a slightly longer to build and can last for a day or two. These are also known to be extremely destructive. However, people are mostly warned about these and have a chance to escape before the situation becomes worse. Tourists planning holiday to such places can postpone or cancel the plan when there is still time and avoid the trauma caused by this situation.

Flash Floods

Flash floods mostly occur within a very short duration of time such as a few hours or even minutes. These are mostly caused due to heavy rainfall, melting of snow or dam break. These are known to be the most fatal among all and can result in mass destruction as these are almost sudden and people do not get any time to take caution.

Conclusion  

Floods disrupt the day to day life in the affected regions. They cause various problems for the people living in such areas. Regions hit by severe floods take months and at times even years to rebuild.

 

FLOOD ESSAY – 3 (400 WORDS)

Flood is a natural disaster that is caused due to the accumulation of excessive water in a region. This is often an outcome of heavy rainfall. Many regions also face flood due to overflow of river or ocean water, breaking of dams and melting of snow. In the coastal areas, hurricanes and tsunamis are known to bring about this condition.

Flood-Prone Regions around the World

Several regions across the globe are prone to frequent floods. The cities around the world that face severe and frequent floods include Mumbai and Kolkata in India, Guangzhou, Shenzen and Tianjin in China, Guayaquil in Ecuador, New York, NY-Newark, NJ, Ho Chi Minh City, Vietnam, Miami and New Orleans. Floods are known to have caused mass destruction in these areas in the past.

How to Control the Problem Caused Due to Floods?

From damaging the environment to disrupting the human life – floods have several negative repercussions that are difficult to deal with. It is thus important to take measures to control the same. Here are a few ways to control this problem:

Flood Warning Systems

It is the need of the hour to set up better flood warning systems so that people are warned about the upcoming problem right on time and they have enough time to safeguard themselves and their belongings

Construct Buildings Above the Flood Level

Buildings in the flood prone area must be constructed above the flood level so as to avoid damage to the property as well as the people living there.

Introduce Water Storage System

The government must invest in building water storage systems to store and reuse the rain water. This way the excessive water can be put to use instead of letting it overflow on the plains and cause flood.

Strengthen Drainage System

One of the main causes of flood is the poor drainage system. It is essential to build good drainage systems to avoid water logging that results in flood.

Install Flood Barriers

Flood barriers should be installed in the areas that are prone to flood. These can be removed once the water recedes.
