Rivers in the escarpment-dominated catchments of coastal NSW are characterised by confined and partly-confined valley-settings in which channels have little capacity to adjust. The key aim of this project is to determine controls on the distribution of floodplains in this landscape. Particular attention will be placed on the role played by stream power in determining the relationship between valley incision and lateral expansion processes along river courses. Understanding controls on these rivers is critical in determining how they modify their form in response to various disturbance events (whether 'natural' of human-induced). Results will provide a rigorous basis with which to explain cross-catchment variability in river forms and processes, aiding our capacity to predict future adjustments to disturbance and develop river management strategies that 'work with nature'.

在新南威尔士州沿海以陡崖为主的集水区，河流的特点是封闭和部分封闭的山谷环境，其中通道几乎没有调整能力。 该项目的主要目的是确定对这一景观中洪泛区分布的控制。 将特别注意流功率在确定河谷下切和沿着河道横向扩展过程之间的关系中所起的作用。 了解这些河流的控制是至关重要的，以确定他们如何修改自己的形式，以应对各种干扰事件（无论是“自然”的人为）。 结果将提供一个严格的基础，以解释跨流域的变化，河流的形式和过程，帮助我们的能力，以预测未来的调整干扰和制定河流管理战略，“与自然合作”。
