The River Basin Management Society is pleased to host this seminar which will include two presentations from 2015 nominees for Healthy Waterways awards. Join us for an interesting evening with our guest presenters, and new and familiar faces from the industry and community.
Drinks and nibbles will be served from 5.30pm. The seminar will commence at 6 pm.
Both presentations will explore issues surrounding nutrient inputs into south east Queensland waterways.
In south east Queensland, cattle-grazed pastures are a predominant land use and contribute towards the nutrient loading of the soil which, during rainfall events leach from the soil and enter our waterways. Excess nutrient loading of our waterways has implications for ecosystem functions and water use from the top of the catchment down to Moreton Bay.
Amanda Neilen’s (Griffith University) research utilised field based and laboratory experiments to examine the role of soil cover in minimising nutrient loss to waterways from grazing enterprises. The outcomes of this research are applicable to rural and urban waterway management, particularly in relation to the use of riparian vegetation in reducing nutrients entering our waterways.
In the second presentation we will hear from Cameron Jackson (QUU) who helped implement the Beaudesert Nutrient Offset Project on the Logan River in late 2013. The project acted as a pilot study contributing toward the development of a now Government approved approach to deliver nutrient offsets by undertaking river restoration activities. . The aim of the pilot project was to offset an increase in the mass of point source nutrients input into the Logan River from Beaudesert sewage treatment plant during ‘wet’ years (when recycled water demand from local irrigators is lower)and avoid costly upgrades to hard infrastructure, while having numerous benefits for local landholders and the environmentand avoid costly upgrades to hard infrastructure, while having numerous benefits for local landholders and the environment. The presentation will look at the science and economics of the project from QUU’s perspective. Misko Ivezich (Alluvium Consulting) will also provide an overview of the modelling, design and delivery aspects of the river restoration works.
