@article{Rick Jaeger_Terry Lucke_2016, title={INVESTIGATING THE RELATIONSHIP BETWEEN RAINFALL INTENSITY, CATCHMENT VEGETATION AND DEBRIS MOBILITY}, volume={12}, url={https://geomatejournal.com/geomate/article/view/1179}, abstractNote={<p>Urbanisation creates the need for engineered hydraulic structures in catchments, floodplains and<br>watercourses. These include piped and open-channel drainage networks, flood control systems and waterway<br>crossings such as culverts and bridges. During larger storm events, debris and other material located higher in the<br>catchment can be mobilised and transported towards these hydraulic structures creating the potential for<br>blockages. This debris is often trapped by the hydraulic structures, causing partial or full blockage which can<br>reduce the flow capacity of the structure. This may cause upstream flooding during high intensity rainfall events.<br>This study investigated the debris transport behaviour in a natural channel. A model of an existing catchment and<br>culvert system in Australia was build based on Froude similitude scaling. Different sized twigs were used to<br>replicate natural debris of various sizes. The experimental results demonstrated that the mobility of debris during<br>rainfall events was dependent on a range of factors including stream depth and width, the size and availability of<br>debris, and on the condition of the riparian vegetation within the catchment. This could have significant<br>implications for culvert design and maintenance procedures.</p> <p> </p>}, number={33}, journal={GEOMATE Journal}, author={Rick Jaeger and Terry Lucke}, year={2016}, month={Oct.}, pages={22–29} }
