Client: Cairns Regional Council
BMT have led the development of coastal hazard maps (sea level rise, storm tide inundation and erosion) for the City of Cairns in Far North Queensland and used this information to undertake a risk assessment of assets and infrastructure of the City under three timeframes (current, 2050 and 2100), incorporating climate change projections.
The hazard mapping developed provides the City and Disaster Managers with a detailed understanding of future risk from a range of coastal climate change impacts including erosion, storm tide and permanent inundation from sea level rise, both individually and cumulatively. This project will also include identifying coastal hazard adaptation options for the Cairns Regional Council. This will include the provision of guidance on land use planning and responses.
In line with the objectives and aims of the Queensland Coastal Hazard Adaptation Strategy [CHAS] program, the project assessed climate change risks of 1034km of sealed roads, other linear infrastructure (water supply, sewer, drainage) and a broad range of commercial, public and private assets in the City. Disaster Management Coordinators in the region (including all levels of government and key stakeholders) were engaged to ensure uptake and effective response to the information. Stakeholder workshops were also held with a broad range of stakeholders to discuss risks, opportunities and options.
The coastal zone of Byron Shire has a history of erosion and inundation related to ocean storm tides and wave attack.
The Queensland Government Department of Environment and Natural Resources contracted Buckley Vann Town Planning Consultants and BMT in 2010 to assist the Department with the development of a proposed planning and assessment code and associated guidelines to support the State Planning Policy for Coastal Management currently in development.
BMT was engaged by the Department of Industry on behalf of the Marine Estate Management Authority (MEMA) to provide strategic risk assessment advice for the TARA process for a pilot project for the Hawkesbury Marine Shelf Bioregion and then for the State-wide marine estate.
The Brisbane River Catchment Flood Study is the most detailed and comprehensive flood study ever undertaken in Australia. The hydraulic models that were developed underwent rigorous calibration. A sophisticated Monte Carlo approach was used to hydraulically model 11,340 flooding scenarios. The result was a robust and defendable set of design events. The study was fully peer reviewed by a panel of independent experts.
