Curtin University is Western Australia’s largest university. The main campus in Victoria Park, Bentley, supports a large student and staff population with a wide range of facilities and open space (approximately 117 hectares in size), including water bodies. Understanding the existing flood risk and assessing the impacts of proposed future development on the campus is important for planning and development decisions.
Stormwater Management Plan
Water Technology was commissioned by Curtin University to undertake a stormwater management plan of the entire Curtin University site in Victoria Park. Previous work had only considered small sections of the site’s catchment in isolation. The purpose of this project was to analyse the impacts of stormwater flooding for the entire site under existing conditions so that problem areas could be identified, and to assess the impacts of any future development. A detailed TUFLOW rain-on-grid hydraulic model was developed using LiDAR, feature survey and design drawings along with pit and pipe data from a collection of sources.
The hydraulics of the site are significantly complex, including ephemeral lakes and numerous infiltration basins. As such, there was a need to work closely with the client to gain an in-depth understanding of the various features in the process of developing a model that was appropriate and reflective of the site.
This stormwater management plan study produced a significantly detailed TUFLOW hydraulic model, which is a valuable tool in identifying the flood risk on the Curtin University site for both existing conditions and future developed conditions. The work included the use of the model to simulate flood behaviour through the proposed ‘living stream’ network. The results from the modelling were used to assess potential impacts on the hydrological regime of the ‘living stream; system, and provided a range of recommended management measures to manage or mitigate any impacts.
