摘    要:本文介绍了一个由法国首先提出的降雨径流流域模型,该模型把以转移函数一阶差分(DPFT)为基础的降雨径流模型与以渐消记忆递推最小二乘法(RLS)实现参数实时估计的自回归滑动平均模型结合在一起,前者用于上游子流域或支流流域:后者用于子流域以下.本文在DPFT参数计算上与原模型有所不同,经试验效果是好的.文中还用国内资料作了一个DPFT模型的算例,模拟精度是较高的.

关 键 词:水文预报  数学模型  降水  径流  回归分析

Abstract:A rainfall-runoff watershed model proposed by french hydrologists is introduced in this paper. In this model, a rainfall-runoff model based on transfer function initial difference is combined with a regressive moving average model, in which the real-time estimation of parameters is realised by the recursive least sguare method, the former can be applied to the upstream sub-basins, the latter to the down-stream rivers reaches. In this paper, some algorithms are different from the original model. An example with home data is provided, and the accuracy is high.
Keywords:hydrologic forecast  mathematical model  rainfall  runoff  regressive analysis
