淮安市龙王山水库流域洪水预报研究及应用

Research and Application of Flood Forecast to Longwangshan Reservoir in Huai'an City

介绍了利用新安江三水源模型计算流域的产流以及分水源及蒸发等的计算,并用变动雨强瞬时单位线计算流域的汇流,用坐标轮换法优选模型的参数.将此方法应用到龙王山水库流域,取得了比较好的预报效果.

This text introduces the Sanshuiyuan Xin'anjiang model to calculate the runoff, and runoff in different layer, evaporation calculation. The variable rainfall intensity instantaneous unit hydrograph is used to calculate the watershed flow; the arithmetic, which change the multidimensional search to single dimensional search, is used to select the optimum parameters. And this method is applied to Longwangshan Reservoir, and a good result is obtained.
