Which is the Most Flooded Country in the World? Most Floods by Country

In general, larger and more damaging inundations have become more common in many countries. Accordingly, more people died due to this disaster. Likewise, these countries suffered from larger economic losses. Which is the most flooded country in the world? 

Countries in the tropical regions are generally more prone to floods. The high flood risks in tropical countries are due to monsoon or tropical cyclone activity, which leads to intense, extreme downpours. The topography and the urban development in these regions can also increase flood risks.

Which is the Most Flooded Country in the World?

Six Asian countries are listed as the most flood-prone countries in the world. From 2024 to 2025, millions of people in those countries were affected by floods. What are those countries?

1. China

China is most flooded place in the world. Each year, this country is hit by more than 25 large inundations. Flood risks in this country are at their highest during the summer. 

Moreover, large inundations generally occur on the riverbanks of China’s biggest rivers, including the Yellow and Yangtze. In July 1931, the deadliest flood in the world swamped China for weeks. 

The causes of this hazard are snowmelt and at least 7 cyclones hitting the country. Accordingly, floodwater submerged an area of 180,000 square km in China. 

Millions of people were reported died in this disaster. The causes of these high fatalities were hunger, diseases, and, of course, being swept away by floodwater. 

2. India

India is the second most flooded country in the world. Almost 400 million people in this country live in flood-prone areas. Large floods are annual disasters in this region. 

In 2007, several Indian provinces were swamped by catastrophic floods. Some of these provinces are Assam, Bihar, and Uttar Pradesh. This disaster killed more than 2,000 people. 

In 2025, Punjab was hit by large floods, the worst in 4 decades of Punjab’s history. This hazard affected roughly 23 districts and more than 3.5 million people.

3. Bangladesh

Which is the most flooded country in the world? Bangladesh is the most flood-prone region in the world due to river overflows. Catastrophic floods have hit this country in recent decades. 

In 1988, an extreme flood occurred in this nation. It is the most destructive in Bangladesh’s history. This inundation covered more than half of the country. Moreover, it affected 30 million people and killed more than 2,000 others. 

In 2024, this country experienced another large inundation. Accordingly, 6 million people were impacted. Moreover, 500,000 people were displaced, and 71 of them died in this disaster. From May to July 2025, massive floods also swamped this country.   

4. Indonesia

One of the most flooded countries in the world is Indonesia. Each year, many floods occur in this country. Still, only a few of them were destructive and triggered high fatalities. 

Now, floods affecting this country are more intense than before. Massive floods, the most destructive in the history of Indonesia, overflowed three provinces at the end of 2025. Moreover, the floods affected thousands of people in those provinces. They also killed 1,200 villagers. 

5. Pakistan 

One of the major issues in Pakistan is flooding. Floods generally swamped the country after torrential monsoon rains. About 75 years ago, a flood in this region killed roughly 2,900 people and destroyed more than 100,000 houses.

In 2025, floodwater submerged several Pakistani provinces after two rivers overflowed and a glacial lake outburst flood occurred. Accordingly, at least 1,000 people died in this disaster. 

This hazard was more devastating than that in 1950. Still, it caused fewer fatalities. It is because Pakistan now has excellent disaster mitigation and warning systems.

6. Vietnam

Decades ago, Vietnam was generally hit by 4 large floods annually. But, inundation is more frequent than before. Now, roughly 7 large floods sweep through Vietnam annually. 

In 1971, massive floods, the deadliest in the country’s history, submerged North Vietnam, affecting more than 1000 communities. In addition, over 100,000 people died in this hazard.  

In 2025, a series of floods made the country to suffer an economic loss of 4 million USD. This disaster caused the country to endure large economic losses and crop failures. 

These failures happened because more than 550,000 hectares of fields were swamped. It is also reported that more than 420 people died in this disaster.

Which is the most flooded country in the world? China has the highest flood risks worldwide. Other countries in Asia are also prone to massive floods. Thus, they should set up effective wireless flood warning systems to minimize flood impact. To create this system, governments can adopt cell broadcasters from smsbroadcaster.com to their warning systems.
