Environmental Modelling Services

Air Dispersion Modelling

• Our team utilises advanced modelling software and methodologies to simulate the dispersion of pollutants from various sources, such as industrial facilities, transportation corridors, and construction sites.

• By analysing factors like meteorological conditions, terrain, and emission sources, we generate detailed predictions of pollutant concentrations in the air across different locations and time-frames.

• This enables our clients to understand potential impacts on surrounding communities and ecosystems, develop effective emission control strategies, and make informed decisions that promote sustainable practices while safeguarding air quality and public health.

Industrial Noise Modelling

• Our approach involves utilising advanced modelling techniques to simulate noise propagation from various sources, such as machinery, equipment, and transportation activities within industrial sites.

• By analysing potential noise levels and their impact on surrounding environments and communities, we provide valuable insights that aid in compliance with local noise regulations and standards.

• Our team also recommends effective noise mitigation strategies, such as sound barriers and equipment modifications, to minimize disturbances and protect the well-being of nearby residents and ecosystems.

Mixing Zone Modelling for Wastewater Discharge

• Our advanced modelling techniques simulate how effluents interact with receiving waters, taking into account factors such as flow rates, water temperature, and the physical and chemical properties of both the wastewater and the ambient water.

• By accurately predicting the dispersion and dilution patterns of pollutants, we help clients ensure compliance with regulatory standards and develop effective strategies for minimizing adverse environmental impacts.

• Our comprehensive approach not only facilitates responsible wastewater management but also supports the protection of aquatic ecosystems and public health.

Groundwater Flow & Water Quality Modelling

• Our expert team employs advanced computational tools to simulate groundwater flow dynamics, helping to understand aquifer behaviour and interactions with surface water.

• By integrating hydrological data with water quality parameters, we can identify potential contamination sources, assess pollutant transport, and evaluate the effectiveness of mitigation strategies.

• This modelling not only supports compliance with environmental regulations but also aids in the development of effective water management plans that ensure the protection and sustainability of vital groundwater resources for both communities and ecosystems.

Marine Hydrodynamic & Pollution Modelling

• Our advanced modelling techniques simulate various scenarios, enabling us to understand how tides, currents, and waves interact with contaminants, such as oil spills or sewage discharges.

• By assessing factors like water temperature, salinity, and wind conditions, we can predict the behaviour of pollutants and their potential impacts on marine ecosystems.

• This information is invaluable for developing effective mitigation strategies, informing regulatory compliance, and supporting environmental impact assessments for projects involving coastal and marine activities.

• With our expertise, we empower clients to make informed decisions that protect marine life and promote sustainable ocean resource management.

Integrated Catchment Management

• Catchments are intricate networks of variables, and effective planning for their future requires an understanding of what makes each catchment unique.

• Our integrated catchment planning approach considers the interconnections within ecosystems and the relationships between these ecosystems and people, encompassing cultural, social, recreational, and economic values.

• By addressing land use, water quality, and biodiversity in a holistic manner, we develop comprehensive catchment plans that promote the overall health of these areas, ensuring sustainable outcomes for future generations.

Flood Modelling & Response

• AJEC provides integrated flood modelling and response services that link predictive analysis with practical, on-ground intervention, enabling flood risks to be identified early and managed effectively when events occur.

• Using advanced geospatial and hydrological tools, we collect, analyse, and visualise data to simulate flood scenarios, map flow paths, and identify vulnerabilities within stormwater networks and critical infrastructure.

• These insights support informed decision-making, allowing clients to prioritise asset renewals, targeted upgrades, and the implementation of nature-based solutions that reduce flood exposure and improve system performance.

• During storms, floods, and other climate-driven events, AJEC delivers timely, engineering-led emergency response services where community infrastructure and environmental assets are at risk.

• Our response work focuses on environmentally responsible repair of damaged, burst, exposed, or contaminated water assets, with particular care in ecologically sensitive areas.

• Beyond immediate recovery, we support infrastructure renewal and resilience upgrades that reduce future flood risk and strengthen long-term adaptive capacity.

Biodiversity & Habitat Restoration Model

• Since human settlement, many of unique ecosystems have faced significant pressures from urban expansion and changes in rural land use.

• These habitats, home to irreplaceable biodiversity found nowhere else in the world, are under threat.

• Drawing on our deep expertise and passion for habitat restoration, we are committed to revitalizing these fragile ecosystems, restoring biodiversity and promoting healthier landscapes.

• Our multidisciplinary team of environmental scientists and engineers is driven to reverse the long-term environmental impacts and reintegrate vibrant, resilient ecosystems into the urban environments where we live and work.

• We can help with:

  - Terrestrial, Freshwater, Wetland and Coastal Ecological Impact Assessments (EcIA)

  - Assessment of Environmental Effects (AEE)

  - Native Planting Plans and Pest Plant Management Planning

  - Watercourse Assessments and Stream Ecological Valuations (SEV)

  - Habitat Mapping and Species Survey

  - Geospatial Analysis

  - Drone Surveys

  - Catchment Planning

Water Sensitive Urban Design (WSUD)

• At AJEC, we integrate water management, ecosystem functionality, and urban design to create regenerative and liveable urban spaces.

• Our Water Sensitive Urban Design (WSUD) services prioritize understanding each site’s natural water cycle, ecological values, and connections to surrounding environments.

• This approach allows us to design solutions that mitigate water quality and quantity impacts while fostering a connection between communities and their local water resources.

• We incorporate green infrastructure - such as wetlands, rain gardens, and permeable pavements—into urban developments to enhance ecological health and create lasting, positive impacts on both the environment and the communities we serve.
