Abstract: Reintroducing riparian vegetation is one of the most popular rehabilitation strategies. Yet considerable knowledge gaps are hampering the development and effectiveness of such efforts. A new streambank rehabilitation technique has been developed in Australia involving the use of native longstem tubestocks. This paper reports on the initial stage of research which characterises a field site before a rehabilitation trial. The field site has also been reconstructed in a reduced Froude scale model for more detailed measurements which will take place in 2007. Methods used to characterise the field site include ADV (Acoustic Doppler Velocimeter) measurements and topographic surveys. The rehabilitation trial involves actual plantings of longstem tubestock in three patches along the outside bank of a large radius bend. The results of preliminary 1D modelling of vegetation patches are presented and areas for improvement discussed.
