COASTAL PROTECTION

We undertake statistical analysis, numerical modelling, asset management and engineering design across the coastal and marine sector

OUR SERVICES

Our coastal engineers and modellers work throughout the coastal zone; from offshore metocean studies, coastal designs at the shoreline, and sediment management within estuaries.  Our work includes coastal and sediment modelling, nourishment and dredge studies, coastal asset inspections, concept and detailed design, and construction supervision.

Coastal Asset Management

Risk-based asset assessments, combining inspections, condition assessments, and numerical modelling for defences, walls, quays, groynes, and revetments

Our Technology: AssetCoast 

Coastal Modelling

Numerical modelling for extreme conditions, cyclones, waves, tides, currents, sediment transport, dredge plume, erosion, shoreline change and beach morphology.

Coastal Design

Planning, economic analysis, benefit:cost assessment, project appraisal, design, drafting, Technical Specification, costing, and construction management.

OUR PROJECTS

Midge Point coastal modelling and boat ramp design

This project developed new Delft3D numerical models to estimate tidal patterns through the northern Mackay coastline and extreme wave conditions at Jimmy’s Rock Road to support the detailed design of a new boat ramp.  The future current, water level and wave conditions were used to design new rock armour protection for the ramp under a 2070 planning horizon.

Burdekin Dune Management Strategy

The project included extreme coastal analysis, coastal erosion modelling and tidal mapping, evaluation of new nature-based dune management strategies, community education, signage, and ancillary structures (fencing, car parks, beach accessways etc). This information was compiled into a phased management plan, combining new on-ground works and engagement

Design for the Maroochy River Groyne Field Renewal Project

This project set out to undertake new R&D in Geosynthetic Sand Containers (GSC), increasing their functionality and lifespan so they can be more widely used for coastal protection.  The project included new investigations, physical testing of new ideas, concept and detailed design, and whole-of-life costing for the replacement of the Maroochy River groyne field.  

Mossman River Estuary Impact Assessment

A coastal, hydrologic and hydraulic modelling estuary to quantify impacts of a new intertidal boat ramp. Our team developed a Tuflow hydraulic model and a Delft3D hydro-morphological model to quantity and minimise impacts.

Strengthening Integrated Flood Risk Management in Philippines, Asian Development Bank

Our team developed a Synthetic Typhoon Event Set that can be used to assess extreme coastal surges throughout the Philippines, to support this Asian Development Bank (ADB) project. The project is being undertaken to identify locations where innovative Integrated Flood Risk strategies can be made, including Nature-Based Solutions.  The project reviewed historic typhoon tracks, undertook statistical analysis, and developed a new track database considering forward speed, bearing, central pressure, environmental pressure and the radius to max winds

Breakwater Extension in the Redlands, Australia

Our engineers have completed the design of an extension to the William Street Breakwater in Cleveland, Queensland.  The current structure provides protection from extreme waves to local infrastructure.  This new project raised and extended the structure, building an allowance for climate change into the designs.  The project included preliminary design, detailed design, all permits and applications, harbour master review, and construction documentation.

Douglas Coastal Hazard Adaptation Strategy (Douglas Shire Council)

A large-scale coastal hazard management strategy, considering present day and future coastal risks.  The initial project included coastal erosion modelling for the 120km coastline.  The study included site-inspections, detailed numerical modelling for waves and erosion, identification of areas exposed to current and future coastal hazards, and prioritisation of at-risk assets, infrastructure and land.  The latter stages included the identification and evaluation of a range of adaptation options tailored to the local Council to reduce or eliminate coastal risks.  These were analysed through a socio-economic appraisal for all viable adaptation options, including both multi-criteria and cost-benefit analysis.

Midge Point Coastal Erosion Management Plan (Mackay Regional Council)

The detailed design and testing of a new rock armour revetment and recurved seawall for coastal protection along the East Rhyl frontage, Wales. The final designs are tested with the Queensland Government Hydraulics Laboratory in 2D (flume) and 3D (basin) to confirm design performance. The project has spanned several phases; investigation of performance standard, coastal flood risk mapping, economic assessment,  concept design, and has now moved into the detailed design and physical testing stage

Emu Point economic analysis of coastal adaptation options

​Working with EvoCoast, this project conducted a coastal erosion economic assessment and Cost-Benefit Appraisal (CBA) of several coastal adaptation options for the Emu Point to Middleton Beach Coastal Hazard Risk Management and Adaptation Plan (CHRMAP).  Prepared for the local Council, the cost-benefit methodology has been designed to provide a quantitative, economic assessment of a range of adaptation options to address erosion vulnerability.  It provides information on the whole life costs of each management strategy devised to mitigate erosion, the damages avoided due to the scheme implementation, and the economic benefits received within the Local Government Area.

Extreme Met-ocean Analysis, Port Moresby (ARUP and JICA)

​​A study for the Government of Papua New Guinea, funded through the Japan International Cooperation Agency (JICA). This assignment was part of Port Moresby Sewage System Upgrade Project (POMSSUP) which is being undertaken to reduce and prevent untreated sewage from being discharged into the sea.  Our team were involved in the estimation of ambient and extreme coastal conditions at the study site, including the assessment of cyclones using Delft3D.

Tidal Harmonics and Storm Surge Characteristics in the Mekong Delta (Mekong River Commission)

​​Analysis of the tidal regime around the Vietnam Delta and the characteristics of storm surges and typhoons. Production of report in support to the Flood Management and Mitigation Programme of the Mekong River Commission (MRC) Secretariat Phnom Pen illustrating the importance to flood management of the influence of tidal conditions, which extend over 400km inland in the Mekong, with recommendations that climate conditions, typhoons and storm surge events are included in all future studies.  

Climate Resilience, Coastal Protection and Management Project, Maharashtra and Karnataka, India (ABD)

​​Our staff were involved in the provision of specialist climate change, coastal engineering and climate change advice. This included the development of a scoping study, review of background documents, in-country meetings, technical advice, and climate change calculations. The project strengthened the resilience of the Indian coast, coastal infrastructure and communities to the adverse impacts of climate change.
