查询词典 river channel

The evolvement of Diffluence River is the more complicated than Single River, because the diversion"s thing is changed with channel"s distortion. The river diversion is the general reflection of a good many factors, which mutually influence and adjust. In particular, when main channel occurs scouring-silting change, which causes the movement of water, sediment, and river bed in river system, the diversion will more be changed, with the study on division of discharge and sediment been further into, some practical engineering problem are solved.

目前，在对河道分流的认识与治理开发上虽取得了不少成绩，但随着社会经济的发展，人们对分流河道演变规律的认识与治理要求越来越高，随着人类对河流改造活动的加剧，河道的水沙条件可能发生急剧的改变，这些变化有可能使分流分沙的缓慢变化加剧，甚至改变原来的分流规律，许多研究者对分流分沙进行了较深入的研究，并能较好地解决了工程实际问题。
