The 1998 China floods (1998年中国洪水) were a series of floods that 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.

Overview

In the summer of 1998, China experienced massive flooding including floods of the Yangtze River, the Nen River, the Songhua River and the Pearl River after massive torrential rains took place. Areas that were most threatened associated the Yangtze include the low-lying basins surrounding the Dongting and Poyang lakes, and surrounding counties in Hubei and Hunan.[3]

Tolls

The event was considered the worst Northern China flood in 40 years.[4] The floods resulted in 3,704 dead, 15 million homeless and $24 billion in economic loss.[5] Other sources report a total loss of 4150 people, and 180 million people were affected.[4] A staggering 100,000 square kilometres (25,000,000 acres) were evacuated, 13.3 million houses were damaged or destroyed.

Yangtze River Flood

The main cause of the flood was due to above average rainfall in the region for several months prior and during the summer of 1998. [6] Aftermath of the 1998 Yangtze River Flood]. Most areas saw double the normal amount of rainfall during the rainy season, with certain regions seeing rainfall levels as much as nearly 3 times the historical average. [6] [7] Combined with above average rainfall since the previous winter, this pushed water levels to above cautionary levels. 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. [6] [7] As much as 1000mm of precipitation was seen in some locations. [7] After briefly shifting north, the same system eventually returned to the region in mid-July. [7] Although the system had weakened, rainfall during this period was more intense and localized. [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. [7] Another 300-500mm of rain was seen across several areas during this second phase, causing significant damage as it flowed into villages and towns. [7] The final period of rainfall occurred in August, with an average of 150-200mm of rainfall seen in most regions. [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. [6] [7] It was also during this period that the dikes began to break, causing further death and widespread damage to property. [7]
