摘要
水沙评价模型的建立对水土保持效益的确定起着至关重要的作用,直接决定计算结果的精度,本文系统总结了近年来在科研工作中建立的黄河中游多沙粗沙区典型支流三川河流域水沙变化评价模型,并对模型的精度进行了验证。
The establishment of water and sediment evaluation model has plaied a very important function to determine the benefit of soil and water conservation and directly decided the precision of computed results. This article systemly summarized the water and sediment evaluation model established in recent year for the typical branch of Sanchuanhe River Basin with the rich and coarse sediment area in the middle Yellow River and has carried on the confirmation of precision to the model.
