摘要
本文建立了一套适用于天然河道长河段、长时段洪水过程复演或预报的一维非恒定流数学模型。将此模型应用于长江上游朱沱至三斗坪河段“８１．７”洪水过程复演计算，计算与实测水位、流量和槽蓄过程均吻合得较为满意。计算结果合理，该模型可望广泛地应用于水利工程实际。
This paper presents a mathematical model on one-dimentional unsteady flow,which can beused to the long-distance and long-term flood routing or prediction in the natural channel.The modelhas been applied to flood routing calculation of upstream reaches,which locate between Zhutuo andSandouping of Yangtze river in July 1981.Computed water levels,discharges and storages agree witheasuered ones.The computed results are reasonable.
