补充资料：分叉型河道
一种平面上分成若干汊道的河道，各叉道间为江心洲所分隔，故亦称江心洲型河道。其流路特征可用分叉指数b.i.来刻划，即b.i.=2×位于河道某区间的江心洲和心滩的总长度沿河道中心线的河床长度当此值大于1.5时，则视为分叉型河道。分叉程度可用分叉系数，即各股汊道的河长总和与分汊段沿河谷方向上的长度的比值来表示。按分叉型河道的外形分为顺直分叉、微弯分叉及鹅头分叉等亚型。分叉型河道较稳定，汊道的发展、消长有明显周期性，汊道的发展主要取决于汊道进口处的分流分沙情况。边界条件在其形成中起着很大作用，其中节点的存在对河道形成、平面形态及演变动态产生了深远影响。节点的钳制使河床束放相间，节点上游的壅水段及下游的展宽段有利于泥沙落淤而形成心滩，并逐步发展成江心洲。展宽段中水流切割过分宽大的边滩，也会形成江心洲。因节点在不同水位时的挑流作用不同，动力轴线交替通过主汊和支汊，故均能保持稳定。此外，较小的比降、含沙量、洪峰变差系数和流量变幅也是分叉型河道形成的有利条件。
