【摘要】 基于SIMHYD降水径流模型,研究了黄河中游无定河流域的水文模拟问题.对无定河流域的7个子流域的日、月流量过程进行了模拟,结果表明:该模型不能很好地模拟无定河流域的水文过程.分析认为:资料的代表性不足、模型本身的局限性及流域下垫面等条件的复杂性是模拟效果不理想的主要原因.更多还原

【Abstract】 Based on the SIMHYD rainfall runoff model,the performance of the model is tested in seven sub-catchments of Wudinghe River basin.And the results show that SIMHYD model can not simulate daily and monthly discharge of Wudinghe River basin well.Analysis indicates that insufficient representative of data,limitation of SIMHYD model itself,and complexity of groundcover in the river basin are main causes resulting in poor discharge simulation result.And hydrologic simulation is still a challenge to hydrologist.更多还原
