Territory size shows the proportion of all people who have died in disasters due to floods, who died there, 1975-2000

Territory size shows the proportion of all people who have died in disasters due to floods, who died there, 1975-2000.

Between 1975 and 2000, over 170 thousand people were killed by floods. Flooding kills people in every region of the world. The count of flood deaths is highest in South America, Southern Asia and Eastern Asia. Central Africa, Japan and Western Europe each account for less that 0.6% of flood deaths.

Venezuela is the territory with the most flood deaths per million people per year, when calculated over a 26 year period. However, 99% of these deaths in Venezuela occurred in 1999. This was also the year when the most flood deaths worldwide occurred.

 

The World's Deadliest Floods As Measured By Death Toll

Death Toll
Notes
1
Huang He (Yellow) River, China
1,000,000 to 3,700,000
One of the major reasons for the flooding is the high silt content that gives the river its yellow tint. The silt, which constitutes as much as 60% of its volume, builds up until the river actually is higher than the surrounding land. The tendency to flood is exacerbated by ice dams which block the river in Mongolia; the dams back up the water, and then release devastating walls of water when they break.

Huang He (Yellow) River, China
900,000 to 2,000,000
-
3
Huang He (Yellow) River, China
500,000 - 900,000
The 1938 flood of the Huang He was caused by Nationalist Chinese troops under Chiang Kai-Shek when they broke the levees in an attempt to turn back advancing Japanese troops. The strategy was partly successful.
4
Huang He (Yellow) River, China
300,000
Chinese rebels destroy the dikes along the city of Kaifeng, flooding the surrounding countryside.
5
Ru River, Banqiao Dam, China
230,000
This flood was caused by the collapse of the Banquia Dam, along with several others, following a heavy rain caused by a typhoon. It is the worst dam related collapse in history.
6
Yangtze River, China
145,000
Although the Huang He has caused more deaths, the Yangtze has had more than 1,000 recorded floods.
7
Netherlands and England
100,000
A combination of high tides and storms flooded the Thames and the Netherlands, killing 100,000.
8
Netherlands
50,000
A seawall on the Zuider Zee failed, flooding the low-lying polder.
9
Neva River, Russia
10,000
An ice dam clogged the Neva, flooding nearby cities.
10
Netherlands
10,000
The failure of a seawall on the Zuider Zee flooded the Dutch lowlands.
 
Geography Review

Review

 

Research and then prepare a two minute case study presentation about a 'recent' flood that has been featured on the news.

You should use PowerPoint or a similar presentation application to display 5 slides. These 5 slides will feature the 5 W's of geography case studies:

  • Where the flood happen? - you should include a map.
  • When did the flood happen?
  • What happened? - explain what the events that happened.
  • Why did the flood happen?
  • Who was affected by the flood?
