Transcript of 1931 China Floods

1931 China Floods
1931 China Floods
Social- The population at the was 400 million, this accounts for twenty percent of the worlds population, making China one of the most densely populated countries in the world. This is the reason for the high death toll.

History- From 1928 to 1930, China experienced drought, therefore it was strange to experience typhoons and heavy rains. These storms broke many levees which lead to the flood.

Economic- China's industries developed and grew from 1927 to 1931. Though badly hit by the Great Depression from 1931 to 1935. Many of the areas hit were rural and not very well developed.

Environmental- The areas affected were very much inland and rural.

Political- The drought had fooled the government and the area was underdeveloped so floods had been unstoppable it was only later on when dams had been built

Technological- The technology was not advanced, the area had been rural and farming land so no protection was built

Impacts
How could these impacts could have been minimised?
The government could have risen awareness of flooding and gotten people prepared. Artificial levees could have been built to support the unstable natural ones. Food supplies could have been sent in to deal with the rising need for food and dams should have been built before the event
Characteristics
Location- The event occurred in the Republic of China. The Yellow River, Yangtze River and Huai River all overflowed. All these were near to the central area of China.

Scale-The overflow of three major rivers in China caused water to rise averagely 1.7 metres above ground. The highest recorded was 16 metres achieved on August 19th at Hankou. The floods affected many other areas of China including Hubei, Hunan, Jiangxi, Hankou, Wuhan, Hanyang and Chongqing covering over 100,000 square km.

Time- This flood lasted for five months, this number varies depending on the river. It occurred in 1931.

In 1931 in Central China, the Yangtze, Yellow and Huai rivers caused one of the deadliest natural disasters ever recorded and most certainly the deadliest disaster in the 20th century.

Factors
Why did the event occur?


Key Developments and Processes


Preparation
Heavy snowstorms in the winter were followed by a spring thaw and heavy rains that raised river levels significantly. Cyclones and heavier rains came in July to August.



China had experienced drought before the event which was unusual. China had experienced many floods, but not of this scale.



There was little to no preparation. Drought had occurred for 2 years before the event, so no one had expected the floods. There was some warning such as increased rainfall and snowstorms but it was too late.
Positive- The positive impacts includes the benefits this event has had on technology and agriculture. People can now rebuild better houses and structures and have more fertile soil with more nutrients.

Negative- Many people died, those who drowned made up 3% of the deaths, while those who died of starvation, disease, cannibalism and homelessness were around 2-3 million. While many buildings had fallen and been destroyed by floods. Crops and farming land had been destroyed to area where people were reliant on these.
