In June 1998, a serious flood occurred in the west and the Beijiang River. On June 28, a flood occurred in Wuzhou Station on the Xijiang River with a peak flood level of 26.51m. On June 24, the Foshan Hydrological Bureau predicted the flood peak of 9.60m at Sanshui Hydrological Station. The water level is 9.60m, which is flood once in 20 years. The flood peak level at Lezhu Station of the Beijiang River Delta in the west is 3.80m, which is an extraordinary flood exceeding 200 years. On June 29, Qiaosanglian encircled the sluice section of Hechuan Village. After the concerted efforts of the party, government and police, the 16km flood prevention second line of defense was successfully constructed to prevent 13,733 hm 2 (206,000 mu) of cultivated land from flooding. July 4 The success of dredging embankment at day closure enabled the flooded 10000hm ~ 2 (150,000 mu) of cultivated land to quickly eliminate the waterlogging and resume production, reducing the direct loss by 3.17 billion yuan and the benefit of flood forecasting by 317 million yuan. Foshan hydrological branch introduced “98 · 6” flood hydrological forecast work.
