【摘要】 岗南、黄壁庄、王快和西大洋水库是南水北调中线工程规划向北京应急供水的4座水库,对水库来水进行快速准确的预报对应急供水调度有着十分重要的意义。针对水库控制流域的水循环特性,选用了双层水箱模型进行水库入流预报。对上下游串联的岗南和黄壁庄水库进行耦合水库调度模型的联合模拟预报,对于相邻的王快和西大洋水库进行了对比流域的试验研究,探索了水箱模型参数移植在缺资料地区水文预报中的应用。率定期的参数自动优选和预报期的验证结果表明:各水库模拟效果较好,各项指标均在合格范围内。更多还原

【Abstract】 Gangnan,Huangbizhuang,Wangkuai and Xidayang are four reservoirs which are planned to provide emergent water supply to Beijing in the Shijiazhuang to Beijing Emergency Water Transfer Project(BSEWTP)which is considered a key part of the Middle Route component of the South-to-North Water Transfer Project.Based on the hydrologic cycle characteristics of reservoirs’ catchments,a two-layer Tank Model was developed to forecast the reservoirs’ inflow.A joint simulation for the serial Gangnan and Huangbizhuang reservoirs was conducted by coupling a reservoir operation model.Parameters transfer of Tank Model for PUB was researched by the contrast between the Wangkuai reservoir and Xidayang reservoir.After automatic optimization of the parameters in calibration period,model validation has been done in a 19-year period.The results showed:the simulation results of the reservoirs were good,and the errors can be accepted.更多还原
