Flood
By SI MA CE FENG
Water is one of the most important things for us.It's importance almost as same as sunlight and air.
Sometimes,if there are too much of water ,it'll be disaster,we call flood.
How does flood causes?
In general,there're tow ways will cause flood.
One, it's rainstorm .For example,if it rain very heavy and non-stop,and our drainage system would not drain it,
water float and run anywhere,river-level raising too fast,flood would happen.
There're another way would cause flood.
For example,there is a famous river in China,call yellow River, which has more than 300 miles of riverbed are higher
3-5 meters than ground.So, there were dyke breaking caused many times of floods until present.
There were one time of famous dyke breaking of Yellow River,called "Huayuankou Dyke Breaking",it happened in Zhengzhou,Henan,China in 1938.
The time backed to Second War.Japanese concentrated many army,intended to attack Wuhan from Zhengzhou.Wuhan was temporary capital of China, by that time.The situation was very dangerous ,and nothing could do.
The president,Jiang Jieshi,had to order his army to bomb out the dyke of "Huayuankou".The idea called "using Water to Replace Army"
In July 9Th 1938,jiang jieshi's army bombed out the dyke.It looked the terrible water ran from the sky, swept away everything when it through whatever.
There were 3 provinces had been flooded,including 44 counties.There were 980,000 people dead and there were 12,000,000 people homeless.
Because the huge flood,Japaness troops got into trouble.
Jiang Jieshi's army grabbed the chance to attack ,and destroyed more than 1000 of them.
Finally,the flood delayed Japaness Army to attack Wuhan at least 3 months.China got a small victory,but payed too much.
So,natural flood is fearful,but flood made by human being our self ,is more frightful.
