河水含沙量 meaning in English
sediment concentration in river
Examples
- The results indicated that with the change of water and sand condition and the altitude of tongguan and the development of the industry and agriculture in recent decades , the water environment of wei river had changed largely , which were shown as follow : annual runoff and seasonal flood decreased sharply ; water stream of large discharge decreased and the range of runoff decreased greatly ; sediment load per year decreased generally , sediment concentration of water increased , and the sand silting up was serious ; water channel swung and shrank , and water regime deteriorated ; frequencies of big floods decreased obviously , and hyper concentrated flood increased obviously ; water levels of the same runoff rose universally , and the frequencies of the floods increased and aggravated ; water pollution was very serious
结果表明,近期随着水沙条件、潼关高程等的变化及工农业的发展,渭河的水环境发生了巨大变化,表现在年水量及汛期水量锐减;大流量级水流出现次数减少,水量减少幅度大;年输沙量总体减少,河水含沙量增大,泥沙淤积严重;河道向摆动型发展,河道萎缩,河势恶化;大洪水发生的次数显著减少,高含沙小洪水明显增多;同流量洪水位普遍抬高,洪灾发生次数增加,洪灾加重;水质污染极为严重。
