Engineering resilient solutions
from catchment to coast.

Littoral Engineering is a specialist consultancy delivering integrated engineering solutions across coastal catchments, shorelines and marine environments. Based in Sydney, we work with councils, developers and asset owners on projects ranging from stormwater and hydrology in coastal catchments through to shoreline protection and marine infrastructure.

Our expertise spans coastal processes, numerical modelling, stormwater management, hydrology, and corrosion protection — enabling us to deliver practical, resilient outcomes from the upper catchment to the open coast.

WHAT WE DO

Specialist coastal &
marine engineering services.

We provide end-to-end solutions from strategic planning and detailed design through to approvals and construction support.

Coastal Hazard & Risk Assessment

Advanced numerical modelling of waves, currents, sediment transport, erosion, and coastal inundation including sea level rise scenarios.

LEARN MORE

Shoreline Protection & Stabilisation

Design of seawalls, groynes, revetments, and innovative living shorelines that balance protection with environmental enhancement.

LEARN MORE

Beach Nourishment & Restoration

Full lifecycle services including sand sourcing investigations, nourishment design, placement methodology, and long-term monitoring programs.

LEARN MORE

Marine Infrastructure Design

Jetties, wharves, breakwaters, boat ramps, marinas and waterfront structures — designed for durability, safety and environmental compliance.

LEARN MORE

Environmental & Regulatory Support

Environmental Impact Assessments (EIA), REF preparation, approvals pathways, and stakeholder engagement for coastal projects.

LEARN MORE

Climate Adaptation & Resilience

Strategic planning for sea level rise, coastal hazard adaptation, and building long-term resilience for communities and critical infrastructure.

LEARN MORE

Stormwater & Hydrology

Hydrological modelling, stormwater management, flood risk assessment and drainage design for coastal catchments and urban developments.

LEARN MORE

Catchment Management & Erosion Control

Erosion and sediment control, catchment-scale land management, and nature-based solutions to protect downstream coastal environments.

LEARN MORE

Coastal Infrastructure Resilience

Corrosion assessment and protection strategies, durability design, and asset management for buildings, structures and infrastructure in aggressive coastal environments.

LEARN MORE
INTEGRATED APPROACH

From catchment to coast.
One connected system.

Upper Catchment

Stormwater management, hydrology, erosion control and land-use planning that protects downstream environments.

Coastal Interface

Shoreline protection, beach nourishment, and infrastructure resilience where land meets the sea.

Marine Zone

Marine structures, coastal processes modelling and environmental management in estuarine and open coast environments.

We understand that coastal challenges don’t stop at the shoreline. Our integrated approach delivers better outcomes by considering the entire system.
