摘要
该文以王茂沟流域为例,通过降雨、径流、输沙实测资料分析及不同流域对比研究,结果表明:淤地坝坝系拦沙作用十分显著。王茂沟流域输沙模数由治理前的18 000t/km^2降低到治理后期的504t/km^2,减少了97%,基本上实现了泥沙不出沟。
The methods of contract research and analysis of measured information about precipitation,runoff and silt dis-charge were employed to study the function of the silt arrester dams to detain silt in Wangmao valley as an example.Results showed that the fanction was very significant. Compared with before harness, modulus of silt discharge de-creased fron 1800t/km^2 to 504t/km^2,being 97%. The target of no silt runing out of the valiey was almost reached.
