北江飞来峡～石角河道洪水演算

River Course Flood Routing from Feilaixia to Shijiao

根据北江飞来峡～石角河道水力特征,分别用线性模型、非线性模型和具有预见期的洪水演算模型对该河道洪水进行了模拟计算.结果表明:三种演算模型的计算精度大体相当,结果令人满意;三种模型与流域水文模型的有机结合,可以应用于该河段洪水预报作业预报、实时洪水预报系统和防汛决策支持系统.

The essay reveals the simulated flood routing along the river course from Feilaixia to Shijiao with linear mode, non-linear mode and forecast period mode according to the hydraulic characteristics. It turns out that the three modes have the same precision in calculation. It also advises that the modes, combined with hydrological mode of river basin, should be used in in-time flood forecasting system of the river course and flood prevention measuring system.
