Hand-held pressure-difference Helley-Smith bedload samplers were used to measure bedload fluxes for the 1998/1999, 1999/2000, 2000/2001 and 2001/2002 wet seasons. The bedload sampling procedure involved the completion of two traverses of the channel with at least four measurement points on each traverse at East Tributary, five at Upper Swift Creek and six at Swift Creek. Minimum sample collection time was 120 seconds and the maximum was 660 seconds. These variations were determined by bedload flux so that no more than 40% of the sample bag was filled at a time.]]> Sat 24 Mar 2018 08:21:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9864 Sat 24 Mar 2018 08:14:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10556 Sat 24 Mar 2018 08:08:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10557 Sat 24 Mar 2018 08:08:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20550 100 m s⁻¹ uprooted approximately 50% of the trees in the study catchment. We use a landscape evolution model with repeated occurrence of the cyclone over a 1000-year simulated period to quantify the effect of pit–mound topography distributions on both sediment transport and landscape evolution by including the fallen trees into the digital elevation model both as a pit–mound and also as a pit–mound and tree trunk. The results show that the inclusion of pit–mound topography substantially reduced erosion for the first 10–15 years of its introduction and adding pit–mound–trunk topography reduced erosion rates even further. The pit–mound and pit–mound–trunk acted as sediment traps, capturing sediment from upslope and storing it in debris dams reducing hillslope connectivity. Model simulations predict average denudation rates for the catchment approximating field measured data. These findings suggest that any tree throw is unlikely to result in landscape instability.]]> Sat 24 Mar 2018 08:02:40 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5640 Sat 24 Mar 2018 07:44:00 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4912 Sat 24 Mar 2018 07:22:58 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3159 Sat 24 Mar 2018 07:18:14 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3160 Sat 24 Mar 2018 07:18:14 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3161 Sat 24 Mar 2018 07:18:12 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45525 Mon 31 Oct 2022 14:24:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41307 Mon 01 Aug 2022 12:23:29 AEST ]]>
