1991年淮河的洪水,从防洪情况看,40年治淮工程效益巨大,但也还存在一些问题。现就淮河上、中游防洪存在的问题、产生原因和解决办法,谈一下个人的看法和建议: 一、存在的主要问题淮河上、中游防洪的主要问题是,阻水障碍多,泄洪流量减少,洪水水位抬高,加重了防汛抢险任务,使一些原来不受或受轻灾的地区,变成了受灾区和重灾区。“中洪水、高水位、大防汛、重灾害”,这是淮河防洪问题的要害。据河南省固始县三河尖水位站1919～1949年31年统计,淮河汛期最高洪水位高于26.5米,年份只有5年,平均6年一次,汛期最高的洪水位为26.96米。据1950～1991年42年统计,三河尖汛期最高洪水位超过26.5米的年份有24年,平均不到两年一次。汛期的量高洪水位高达29.84米,较建国前汛期的
In the flood of the Huaihe River in 1991, judging from the flood control situation, the Huaihe River hydropower project has achieved great benefits in 40 years, but there are still some problems. Now on the Huaihe River, the middle reaches of the flood control problems, causes and solutions, talk about personal views and suggestions: First, the main problems Huaihe River flood control in the middle of the main problems is that there is more water blocking obstacles to reduce flood discharge, Flood water level elevation, aggravating the task of flood control and rescue, so that some did not suffer or suffer from minor disaster areas, into a disaster area and hardest hit. “In the flood, high water level, flood control, heavy disasters,” which is the key issue of Huaihe flood control. According to the statistic of Sanhejian water level station in Gushi County, Henan Province in 1919-1943, the highest flood season in the Huai River flood season is higher than 26.5 meters, with a year of only 5 years and an average of 6 years. The highest flood season flood level is 26.96 meters. According to the statistics of 42 years from 1950 to 1991, the highest flood season in the Three River Peaks exceeded 26.5 meters in 24 years, averaging less than once in two years. The flood season high flood level as high as 29.84 meters, compared with the pre-founding flood season
