Stream power and river morphology in partly-confined valleys of coastal New South Wales, Australia

新南威尔士州沿海以悬崖为主的集水区的河流具有受限和部分受限的山谷环境，在这些环境中，河道几乎没有调整的能力。该项目的主要目标是确定对这一景观中泛滥平原分布的控制。将特别注意河流动力在确定河谷切割和沿河道横向扩张过程之间的关系方面所起的作用。了解对这些河流的控制对于确定它们如何改变其形态以应对各种干扰事件(无论是自然的还是人为诱导的)至关重要。结果将提供一个严格的基础，用来解释河流形态和过程中的交叉集水区变异性，帮助我们预测未来对干扰的调整，并制定“与自然合作”的河流管理战略。

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'.
