木材在形成和维护复杂的动态洪泛区表面的作用是重要的，迄今为止已经收到了相对有限的关注相比，在通道栖息地的过程。本文探讨的作用，堵塞的重要代理渠道：河漫滩的相互作用。我们借鉴了一个具体的案例研究，以及从文献中的例子表明，虽然相互作用的过程不同，由此产生的动态洪泛区拼凑是一个共同的特点，河流与堵塞。此外，我们认为，在山区和低地河流环境中的多个通道模式的演变和维护中的一个重要因素是存在的堵塞。这些意见有重要的影响，河流恢复的参考目标的定义。这项研究的具体结果表明：
The role of wood in the formation and maintenance of complex dynamic floodplain surfaces is important and to date has received relatively limited attention compared to in-channel habitat processes. This paper explores the role of logjams as important agents of channel:floodplain interaction. We draw on a specific case study as well as examples from the literature to show that although the processes of interaction differ, the resulting dynamic floodplain patchwork is a common feature of rivers with logjams. In addition, we contend that the presence of logjams is an important factor in the evolution and maintenance of multiple channel patterns in both montane and lowland river environments. These observations have important implications for the definition of reference targets for river restoration. The specific results of this research show:
