River sensitivity to change: An assessment of threshold shifts between River Styles in Coastal NSW. Over 70% of coastal catchments in northern NSW comprise confined or partly-confined valleys in which floodplains are absent or discontinuous. Evolutionary controls on floodplain presence and their sensitivity to disturbance since European settlement will be explained. Increased understanding of the character, behaviour and evolution of these river types will provide a generic framework to assess ....River sensitivity to change: An assessment of threshold shifts between River Styles in Coastal NSW. Over 70% of coastal catchments in northern NSW comprise confined or partly-confined valleys in which floodplains are absent or discontinuous. Evolutionary controls on floodplain presence and their sensitivity to disturbance since European settlement will be explained. Increased understanding of the character, behaviour and evolution of these river types will provide a generic framework to assess river sensitivity to change. The understanding achieved via this project will form the basis upon which to manage these rivers in an environmentally sustainable manner.Read moreRead less
Stream power and river morphology in partly-confined valleys of coastal New South Wales, Australia. 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 val ....Stream power and river morphology in partly-confined valleys of coastal New South Wales, Australia. 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'.Read moreRead less
