【摘要】 本文是文在如下几方面的进一步深入:将原计算区间的上游边界从离可口70km的竹岐站移到离河口20km的南平十里庵站,使下游河段洪水预见期延长到18—19h;计算了有支流的较复杂的河段;用数值模拟确定了欠缺的地形参数的等效值,使缺地形参数的河道实行数值预报成为可能;提出了现场预报的具体实施方法。更多还原

【Abstract】 The research work presented here is an extension of the preceding paper, Some advancements achieved in the prediction of flooding process are summarized: the prediction time course is prolonged to as long as 18-19 hours through extending the up-reach boundary from Zhuqi Station, 70 km far from the estuary, to Silian which is 200 km far from the estuary; regions complicated with tri-butaries are included in the computation of flood; definition of equivalent values for topographic parameters by simulation makes it possible to use numerical prediction in tidal rivers whose topographic parameters are lacking; the way to make real-time prediction on the spot has been proceeded.更多还原
