It is proposed to build a luxury hotel on the site adjacent to the foreshore at Fort Hill in Darwin. The Northern Territory Government legislation requires habitable areas to be elevated above the 1000 year inundation level. The site will also need protection from cyclonic wave action at this storm tide level.
A seawall was designed for the shoreline of the site to protect the infrastructure from damage due to wave action and to control the volume of water carried towards the facility with each wave.
Assessment of the design conditions at the hotel required the generation and numerical modelling of wind fields associated with the 1000 year cyclone to establish storm surge height and wave heights at the site for this event. The models used were TUFLOW FV which is a 2D finite volume hydrodynamic model developed by BMT and SWAN (Delft University of Technology 2006) which is a 3rd generation spectral wave model to establish design wave heights for the seawall. The seawall was then designed using the results from this numerical modelling and tested in a physical model which resulted in confirmation of the design of the proposed seawall.
We developed a 3D hydrodynamic and water quality model of the region around the Abrolhos Islands in Western Australia. In collaboration with the University of Western Australia, model results were used to assess the impact of proposed finfish aquaculture on the surrounding environment.
We were commissioned by the Abu Dhabi Environment Agency to undertake advanced numerical modelling at a site within the Arabian Gulf. This was to assess the viability of developing aquaculture operations at the site.
Seqwater is the Queensland Government Bulk Water Supply Authority and manages over $11 billion of water supply infrastructure - including dams and weirs, conventional water treatment plants, a desalination plant, the Western Corridor Recycled Water Scheme, as well reservoirs, pump stations and more than 600 kilometres of bi-directional pipeline network. As part of Seqwater's climate change risk management, this project assessed climate change vulnerability of Seqwater's built assets.
Following on from our role in assisting Stockland to carry out environmental assessments and obtain federal approval for the project, we have been responsible for the planning and design of the stormwater quality and flood risk management strategy for the Aura site as well as on-going surface and groundwater monitoring.
