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。

The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统，本文分别对它们的形成与发育、地貌特点及动态变化进行了分析，并探讨了影响其发育的主要因素，即来水条件、来沙条件、空间条件，划定了其主要发育阶段，即形成期、成熟期、衰亡期；在上述分析的基础上确定了潮盆—潮沟系统的主要功能，即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态；同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

Concentrations of heavy metals in the suspended matter and sediment are not obviously affected by elutriation of stream and dilution of tributary stream. This feacture does not change even in the distant reach downstream. Therefore, the suspended matter and sediment are the potential source of heavy metal contamination to the waters for industry and agriculture use.

河流的地质、水文特征决定了河流悬浮物和沉积物成为河流中重金属搬运迁移的主要载体，在几十公里的下游水域中悬浮物和沉积物中重金属含量没有受到其它支流清澈水体的稀释，成为下游工、农业用水的潜在污染源。

Within the embayment, the sediment accumulation rates are relatively low, with an order of magnitude of 〓, due to a small sediment supply.

Based on calculation of silt-deposit sediment, the mode of sediment budget of Changjiang Estuary is established for the first time.

在冲淤量定量计算的基础上，首次构建了较精确的长江口泥沙收支平衡模式。

Based on the theory of tidal flow and sediment motion, a 2-D depth-integrated mathematical model for the Jiaojiang Estuary is developed by using explicit scheme of finite difference on the triangle elements. The results show that the rotary currents occurring in this area can be simply and effectively simulated by the model. Meanwhile, the suspended sediment concentration simulated is in agreement with the field data.

本文根据椒江口实测水文地形资料，从平面二维水流泥沙基本方程和基本理论出发，采用三角单元有限差分法对水流泥沙方程显示求解，对椒江口潮流泥沙进行了数值模拟，模型简单实用，较好地再现了具有旋转潮波性质的椒江河口水流运动特征，含沙量场也得到了基本正确的反映。

At the confluence zone, due to the jacking of current from main stream and tributary stream, the mixing and turbulence of current is so strong and the loss of energy is so large that the balance of water and sediment is broken which could causes sediment particle and coarse grain to deposit and forms shallow shoal at river mouth or eyot.

天然河流中存在着大量的干、支流交汇的河段，在干支流相汇处，由于干、支流两股水流相互顶托，交汇区内水流紊动掺混作用强烈，能量损失很大，干、支河流原有的水沙平衡状态被打破，可能导致泥沙颗粒、尤其是粗颗粒卵石在汇合口处大量淤积，形成河口浅滩或江心滩。
