河流改道 river migration
river diversion
- 自从河流改道之后,死亡湖盆就没有了稳定的活水注入。
Dead Vlei has not had regular water since the river changed its course. - 但是在边缘地带,其数量有所减少,主要归咎于其生活环境的改变、水坝建设、河流改道、湿地干涸以及环境污染。
On the periphery of its range, populations have declined, primarily due to habitat modification, dam construction, river flow modification, wetland drainage, and pollution. - 该国在水源领域的活动过于频繁,不仅国内如此,国外亦然——在非洲和巴基斯坦建设水坝、在莫桑比克和菲律宾寻找土地、为一己用途使河流改道。
It is hyperactive in the world of water, not only at home but abroad—building dams in Africa and Pakistan, looking for land in Mozambique and the Philippines, diverting rivers for its own purposes.
