水文测站水位—流量关系的变化,特别是洪峰流量—水位关系的变化,是测站下游相当长河段中影响泄流能力诸因素变化的综合反映,是了解河床发育或萎缩情况的重要依据。 蚌埠水文站从1915年设站观测,除1938—1945年和1949年缺测外,至1994年共计有70年的流量记录:1948年前25年,1950年后45年。这80年中70组洪峰流量—水位(Q_(max)～G_(max))的资料,对于认识蚌埠以下淮河干流相当长河段两堤间河床过流能力的变化及成 The change of hydrological station water level-flux relationship, especially the change of peak flow-water level, is a comprehensive reflection of the factors affecting the discharge capacity in the relatively long reach downstream of the station. It is an important basis for understanding the development or shrinkage of the riverbed. Bengbu Hydrometric Station was established in 1915 to observe the station. Except for the deficiencies in 1938-1945 and 1949, a total of 70 years of traffic records were recorded in 1994: 25 years before 1948 and 45 years after 1950. The data of 70 sets of peak flow-water level (Q_ (max) ~G_ (max)) over the past 80 years are of great significance for understanding the changes of riverbed overcurrent capacity between two embankments in the relatively long reach of Huaihe River below Bengbu,
