淮河入湖河口段是对淮河中游河流动力特性及河道整治有特别重要意义的河段,也是观测研究最为薄弱、应尽快加强研究的河段。根据1982、1991和1996年洪水的实测资料,对淮河蚌埠以下河道段和入湖河口段水面比降的比较表明:后者洪水水面比降大于前者,入湖河口段泄洪不畅。 The mouth of the Huaihe River into the lake is of special importance to the dynamic characteristics of the river and the river regulation in the middle reaches of the Huaihe River. It is also the section where observation and research are the weakest and should be strengthened as soon as possible. According to the measured data of floods in 1982, 1991 and 1996, the comparison of the water surface ramps of the following river channels and inlet estuaries at Bengbu in Huai River shows that the flood water surface ratio of the latter is lower than that of the former, and the flood discharge at the estuary reaches the lake is sluggish.
