In 1998, catastrophic floods occurred in the whole area of the Yangtze River basin. The floods were primarily caused by poor management of the rivers, which were overwhelmed by extreme weather in 1931. Indeed, after a strong El Niño in 1998, similar floods struck the Yangtze River Basin, causing $44 billion in damage and 3,656 deaths. [5] Other sources report a total loss of 4150 people, and 180 million people were affected. Short Term Responses Long Term 62,500,000 acres were flooded between the beginning of June - September (about 3 months) Area flooded vs. 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. [6] 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. https://earth.esa.int/.../zaoP2lUloYKv/content/flood-yangtze-china-july-1998 Immediate online access to all issues from 2019. The core study area is located in the most strikingly meandering and complex stream network section of the middle Yangtze River (Fig. Intensifying anthropogenic activity in the last century, including deforestation, dyking, and lake–coast reclamation etc. 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. It is characterized high water level, large flood volume and long lasting. 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. Multiple studies also suggest that global warming is likely increasing the intensity of the monsoon in Asia. 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 … 22(5), 697–709. 36-141 (in Chinese). 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. 52(3), 268–277 (in Chinese). 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. It follows a visit to China in 1999 by a Unep team to establish the causes of the 1998 floods. China Statistics Press. Wang, J. Background. Lu, X. and Higgitt, D.
