With the case of Lujiahe shoal reach,discussion on countermeasures to the navigation issues related to high gradient slope and large flow velocity is presented in this paper.
以芦家河浅滩段为例,讨论了长江中游沙卵石河段坡陡流急碍航现象的治理对策。
Along with the vigorously development of construction projects,a large number of very steep slopes (>25°) are produced by human beings,on which resulting in serious soil erosion.
随着各项开发建设项目的大力开展,人为地产生了大量>25°的急陡坡坡面,造成严重的土壤侵蚀。
