1982年7月末至8月初,黄河三花间(即三门峡至花园口区间,下同)连降暴雨和大暴雨持续时间长,伊、洛、沁、黄并涨,致使黄河花园口站8月2日19时洪峰流量达15300秒立米,为建国以来黄河下游出现的第二大洪峰。分析此次洪水的特点,可知形成该次洪水的暴雨与形成1761、1954和1958年洪水的暴雨极为相似。说明此类暴雨发生机率很大,今后三花间还可能发生大洪水。一、“82.8”暴雨洪水的特点 1982年8月洪水(简称“82.8”洪水,下
Between the end of July and the beginning of August, 1982, heavy rains and torrential rains continued for a long time in the three flower farms of the Yellow River (ie, Sanmenxia to Huayuankou interval, the same below), with the increase of Iraq, Loh, Qin and Huang and the rise of the Yellow River Huayuankou Station on August 2 At 19 o’clock peak flow of 15,300 seconds Li meters, since the founding of the lower reaches of the Yellow River the second largest flood peak. Analyzing the characteristics of the flood, we know that the torrential rain that formed the flood was very similar to the torrential rain that formed the floods of 1761, 1954 and 1958. This shows that the incidence of such heavy rain is very large, and the floods may occur among the three flowers in the future. First, “82.8” characteristics of storm flood August 1982 Flood (referred to as “82.8” flood, under
