Application of SCEM-UA Algorithm to Xinanjiang Model in Meishan Reservoir Watershed

将SCEM-UA算法内嵌于新安江模型中,利用梅山水库流域水文资料对该算法优选的参数结果进行分析.参数优选主要针对模型的敏感参数,并用实测资料对其验证分析,最后计算洪水精度评定指标分析高水过程模拟结果.研究表明,SCEM-UA算法能够快速有效地对新安江模型参数进行优选,并且基于该参数率定结果的新安江日模型在梅山水库流域上运行效果良好.

SCEM - UA algorithm is embedded in the Xinanjiang model to optimize parameters in Meishan reservoir watershed. The sensitive parameters are optimized and the result is proved base on observation data. The paper calculates flood accuracy evaluation indexes of high-water level simulated flow. The results show that it is effective to combine SCEM-UA into Xin＇anjiang model＇s parameters optimization; and the parameters are applied well to Meishan reservoir watershed.
