今年淮河洪水位高,洪水滞留中游,造成沿淮大面积内涝。将1991年的洪水情况与1956、1954等年比较,可以得出今年淮河水位、流量与往年的差异。一、1991年洪水与相关年水位、流量的差异 1、王家坝站在一般涨水情况下,王家坝水位28.83米,“91.6”与1956、1954年的河道流量分别为4570、7760、7030立方米每秒,“91.6”比1956、1954年分别减少泄量3190、2460立方米每秒。“91.6”王家坝洪峰水位29.54米,流量6630立方米每秒,1954年与此
Huaihe flood this year, high floods, the middle reaches of floods, resulting in a large area along the Huaihe River waterlogging. Comparing the flood situation in 1991 with the years of 1956 and 1954, we can draw the conclusion that the difference between the water level and the flow in the Huaihe River this year and the previous years. First, the flood in 1991 and the year the water level and flow differences 1, Wangjiaba station under normal circumstances, Wangjiaba water level of 28.83 meters, “91.6” and 1956, 1954, the river flow were 4570,7760,7030 cubic meters Meters per second, “91.6” than in 1956, 1954, respectively, to reduce the discharge of 3190,2460 cubic meters per second. “91.6” Wangjiaba peak flood 29.54 meters, flow 6630 cubic meters per second, with 1954
