This is a research report concerning the Yangtze river flooding in 1998, which led to extreme impacts on its home country and great actions of the Chinese government. [7] Although the water had begun to subside at this point, this extra rainfall caused further damage to homes and farmland in the surrounding areas. Xu, G. Q.: 1992, Flood Prevention, Water Resources and Hydro-Electricity Press House, Beijing (in Chinese). [6][7] Combined with above average rainfall since the previous winter, this pushed water levels to above cautionary levels. In the summer of 1998, China experienced massive flooding of parts of the Yangtze River, resulting in 3,704 dead, 15 million homeless and $26 billion in … Damage to the surrounding area also inlcuded many old trees and shrubbery, this not only destroyed habitats but also worsened the after-effects of the floods. Overall, floods this summer have left 219 people dead or missing — the central government doesn’t consistently separate the figures in official announcements — and destroyed 54,000 homes, according to Zhou. In the summer of 1998, China experienced severe flooding of the Yangtze River, the Nen River, the Songhua River and the Pearl River after torrential rains took place.

[7] The final period of rainfall occurred in August, with an average of 150-200 mm of rainfall seen in most regions. Widespread flooding in the Yangtze basin causes deaths as overflowing rivers drown streets. Yangtze is the longest river in China, and floods are the big danger in its middle and lower reaches. Chen, X.: 1996 An integrated study of sediment discharge from the Changjiang River, China and the delta development since the mid-Holocene, J. Coastal Res. The peak of flood, volume of flow, and duration were all record-breaking. Valley is home to 400 million people. “It can only partially and temporarily intercept the upstream floods, and is powerless to help with floods caused by heavy rainfall in the middle and lower reaches of the Yangtze River,” he said.

Tags: yangtze river… It was aimed at both generating power and reining in the ferocious Yangtze, the cause of many terrible floods in Chinese history. 3rd longest river in the world – 6380km. Therefore, stopping floods may be changed as flood [6][7] It was also during this period that the dikes began to break, causing further death and widespread damage to property. Between the actual floods and the following famine and disease, up to 4 million people died, making it the deadliest natural disaster in recorded history. Controlling Yangtze River Floods: A New Approach By Dr. Jamie Pittock and Dr. Ming Xu After nearly a millennium of efforts to control floods in the Yangtze River basin with dikes, polders and other hard engineering measures, the Chinese government adopted a radically different approach after the disastrous 1998 floods.

Yangtze River floods, floods of the Yangtze River (Chang Jiang) in central and eastern China that have occurred periodically and often have caused considerable destruction of property and loss of life. Perry, A. H.: 1981 Environmental Hazards in the British Isles, George Allen & Unwin, London, 191 pp. Most areas saw double the normal amount of rainfall during the rainy season, with certain regions seeing rainfall levels as much as nearly three times the historical average. The most recent major flood in 1998 causes 14 million homeless and $24 billion in economic losses (Yin et al. These images were acquired during the floods in China at the station of Ulan Bator (Mongolia). In 1998, catastrophic floods occurred in the whole area of the Yangtze River basin. The Yellow, Yangtze, and Huai Rivers of China flooded in 1931, inundating almost all of central China in the worst natural disaster in the nation’s history. The core study area is located in the most strikingly meandering and complex stream network section of the middle Yangtze River (Fig. Rainy Weather Causes Major Floods In China Heavy ... Wednesday to open all 10 spillways for the first-time ever in an effort to control rising water on a reservoir along the Yangtze River. Causes of Yangtze Floods in 1998 1998 flood survivors Severe rainfall was the main cause of the floods but man-induced factors included deforestation of erosion-subverting forests in the Yangtze river basin and other areas also contributed to the disaster. White, G. F.: 1974, Natural Hazards: Local, National, Global, Oxford University Press, Oxford. It is characterized high water level, large flood volume and long lasting.

Filed under china , extreme weather , floods , yangtze river , … The Yangtze, at 6,300 km (3,900 miles), is Asia's longest river and the world's third longest. The main cause of the flood was due to above average rainfall in the region for several months before and during the summer of 1998. Third, the construction of levees has caused flood levels to rise due to restricted flood discharge capacity. Still, the causes of disaster are similar: the subtropical high-pressure moved northward before falling southward and finally stabilizing, but the impact duration has not been as long as that in 1998.

Consequently, the discharge capacity decreased to 60,000–68,000 m 3 /s, which is sufficient only for ordinary floods. Multiple studies also suggest that global warming is likely increasing the intensity of the monsoon in Asia. The peak of flood, volume of flow, and duration were all record-breaking. Superimposed image Therefore, stopping floods may be changed as flood control or flood protection. During the catastrophic Yangtze floods of 1998, which killed 4,000 and ruined 7 million homes, heavy rain triggered floods in upstream areas as well. On July 2, the Yangtze River experienced its first flood peak of the year. An integrated approach isneeded to produce a balanced management plan that canmeet the financial needs of local people in thecatchment area as well as reduce flood risk to theindustries and urban residents in the middle basin ofthe Yangtze. Building and infrastructural remains polluted the basin for some months afterwards. Each year, monsoon rains and Himalayan snow melt combine to produce higher river levels. Managt The floods were reported to have killed 3,656 people, destroyed 5.7 million homes and damaged seven million more, and forced 14 million people to move to new areas.

Extensive reclamation of the lakes andfluvial islands in the middle basin has considerablyreduced the floodwater storage and drainage capacityof these natural landscapes of the Yangtze Basin.Deforestation in the catchment area has induced soilerosion, resulting in a large amount of sedimentdeposited in reservoirs whose storage capacity is thusreduced. This paper examines the main causes ofthe 1998 flood on the Yangtze and addresses a numberof issues related to the exploitation of naturalresources and counter-measures to the flood hazard.The records show that both the amount of precipitationover the catchment and the floodwater discharge fromthe upper basin did not exceed the historical maximum,but water levels in the middle … Learn more about Institutional subscriptions. Short Term Responses Long Term Wang, J. In the summer of 1998, China suffered the worst floods in over 44 years.

However, judging from the rainstorm duration, intensity and impact range, the disaster in the Yangtze River Basin this year is weaker than the one in 1998. 1. Multiple studies also suggest that global warming is likely increasing the intensity of the monsoon in Asia. It is characterized high water level, large flood volume and long lasting. Rain water absorbed by forests and vegetation flows more slowly to rivers and streams, preventing flooding. Natural Hazards 22, 165–184 (2000). PubMed Google Scholar, Zong, Y., Chen, X. 1. [7] Another 300-500 mm of rain was seen across several areas during this second phase, causing significant damage as it flowed into villages and towns. The 1998 China floods (1998年中国洪水) lasted from middle of June to the beginning of September 1998 in China at the Yangtze River[1] as well as the Nen River, Songhua River[2] and the Pearl River. Natural Hazards This year's floods in China have officially caused some 1,000 deaths and forced over 5.5 million people to evacuate their homes. The Changjiang Water Resources Commission reported the water level had reached 146.97 metres with peak inflows of 53,000 cubic metres per second, the same rate as the 1998 floods. Thus, this archetypal pattern tended to lead a flood event over the Yangtze River Basin which may cause very large economic losses and human causalities (e.g., the flood event in 1998 [5, 6]). volume 22, pages165–184(2000)Cite this article. 46, 733–742. The 1998 Yangtze River floods were a series of major floods that lasted from middle of June to the beginning of September 1998 along the Yangtze. Establishment of the Great Jinjiang levee caused silting up of the riverbed and valley in the mid-reaches of Yangtze. The most recent major flood in 1998 causes 14 million homeless and $24 billion in economic losses (Yin et al.

Nanjing University, Special Issue on the Causes and Countermeasure of Natural Disaster, pp. Background. The main cause of the flood was due to above average rainfall in the region for several months before and during the summer of 1998. In this paper, I’m aiming to analyze the earth scientific and socio-economic aspects of the 1998 … Afterwards, the government wasn’t able to organize enough relief efforts. This file footage compilation shows the flooding of China's Yangtze River in 1998. This paper examines the main causes ofthe 1998 flood on the Yangtze and addresses a numberof issues related to the exploitation of naturalresources and counter-measures to the flood hazard.The records show that both the amount of precipitationover the catchment and the floodwater discharge fromthe upper basin did not exceed the historical maximum,but water levels in the middle basin were recordedmuch higher than the historical maximum.

Strengthening the flood defence to protectpeople living on the floodplain has raised the waterlevel during the flood. Following the 1998 floods, the government convinced 2.4 million people to leave the Yangtze River floodplains, restoring 1,000 square miles. It was soon discovered that the high water level and its long duration are not isolated phenomena, but representative of the two general tendencies of flood disasters in the middle reach of Yangtze (Table 1). 46(4), 427–435 (in Chinese). [7] After briefly shifting north, the same system eventually returned to the region in mid-July. Among the most recent major flood events are those of 1870, 1931, 1954, 1998, and 2010.

China’s worst floods in recent years were in 1998, when more than 2,000 people died and almost 3 million homes were destroyed, mostly along the Yangtze. © 2020 Springer Nature Switzerland AG. However, judging from the rainstorm duration, intensity and impact range, the disaster in the Yangtze River Basin this year is weaker than the one in 1998. 62,500,000 acres were flooded between the beginning of June - September (about 3 months) Area flooded vs. [6][7] As much as 1000 mm of precipitation was seen in some locations. The Communist … 1). Further Reading The floods can be split into three general stages, beginning when one of the strongest subtropical highs in history arrived in the Yangtze River Basin during mid-June and lingered, providing sustained heavy rainfall for a period of roughly two weeks. The flood caused a direct economic loss of more than 200 billion yuan. The State Statistical Bureau of China: 1995 Report of the Damage Caused by Disasters in China. [7] During this second period of rain, many surrounding lakes and rivers broke record high water levels and overflowed into the Yangtze River, causing a sudden sharp rise in water levels. Areas that were most threatened associated the Yangtze include the low-lying basins surrounding the Dongting and Poyang lakes, and surrounding provinces in Hubei and Hunan.[3].
