利用1998-2005年的洪水资料对马斯京根模型参数进行优选,优选润河集、横排头、阜阳闸至正阳关最优的河道汇流参数,并对该优选参数值进行验证,预报洪水过程平均不确定性系数在0.85以上,预测洪峰流量误差控制在8%以内,达到较高预报作业精度。
Using from 1998 to 2005 flood data for Muskingum model parameters optimization,optimization runheji,Henpaitou head,Fuyang gate to zhengyangguan optimal convergence parameters and validation of the optimized parameter values,prediction The average uncertainty of flood coefficient above 0.85 is forecast to peak flow error control within 8%,reaching a high accuracy of forecasting operations.
