Comprehensive technical solutions from coastal and marine engineering to water management; from numerical modelling to industrial marine systems.
Design · Analysis · Simulation
HEC Engineering designs coastal structures such as breakwaters, pier systems, seawalls and jetties to the highest standards of safety and functionality by integrating wave loads, soil properties and seabed conditions. Every project is supported by site-specific wave climate and hydrodynamic analyses alongside whole-life cost and environmental impact assessments.
Erosion Control · Resilience · Sustainability
HEC Engineering provides long-lasting solutions against coastal erosion, wave action and storm damage by evaluating a wide range of structural options — rubble mound, revetment, rock fill and flexible protection systems — against site-specific conditions. Sea-level rise due to climate change and extreme weather events are also accounted for during design.
Recreation · Sustainability · Aesthetics
HEC Engineering delivers integrated beach design solutions that preserve the natural character of shorelines while enhancing their recreational function. Beach nourishment and fill projects developed with wave-current dynamics and sediment transport pathways in mind create aesthetic coastal spaces where swimming, water sports and tourism can take place safely and sustainably.
Concept · Implementation · Optimisation
Serving a broad spectrum from commercial ports to yacht marinas and fishing harbours, HEC Engineering provides comprehensive technical consultancy at every stage of port planning — from concept design to detailed engineering. Projects are supported by in-harbour hydrodynamic, circulation and seiching analyses to achieve optimum operational efficiency and structural longevity.
Numerical Modelling · CFD · Prediction
Using advanced numerical modelling tools, critical coastal processes such as wave climate, current regimes and water levels are simulated at high resolution. These analyses form a reliable data foundation for coastal structure design, environmental impact assessment and operational planning, technically underpinning project success.
Sediment · Erosion · Deposition
Understanding and predicting sediment movement in river, coastal and submarine environments plays a key role in solving many engineering challenges. HEC Engineering uses advanced sediment transport models to forecast coastal erosion, deposition, channel infilling and long-term changes in seabed morphology, developing effective management strategies from these insights.
Resonance · Operational Safety
Long-period waves and resonance effects within a harbour basin can jeopardise loading-unloading operations and compromise structural integrity. HEC Engineering identifies critical frequency bands and resonance conditions through harbour seiching analyses, ensuring operational safety through layout adjustments and wave-damping structures.
Flow Analysis · Water Quality · Optimisation
Ensuring adequate water circulation within a harbour basin is critical to preventing sediment accumulation, water quality issues and adverse environmental impacts. HEC Engineering analyses in-harbour flow fields using advanced 2D/3D hydrodynamic models to provide design recommendations that optimise circulation.
Breaking · Reflection · Coastal Dynamics
Waves travelling from deep water to the shore pass through many complex physical processes — shoaling, breaking, reflection and diffraction along the coast. Accurately modelling these transformations is indispensable for structural design loads, coastal safety and energy resource assessment; HEC Engineering has high-resolution analysis capability in this field.
CFD · Process Units · Digital Twin
HEC Engineering analyses the process units and inter-unit hydraulic transitions of water and wastewater treatment plants in detail using Computational Fluid Dynamics (CFD). Flow fields in aeration basins, sedimentation and clarifier tanks, distribution structures and connecting channels are modelled in three dimensions to detect efficiency-reducing problems such as dead zones, short-circuiting and uneven flow distribution. The resulting models are developed into a digital twin infrastructure that enables real-time monitoring and scenario-based optimisation, delivering concrete design improvements that enhance treatment performance, hydraulic capacity and energy efficiency.
Outfall · Dilution · Environmental Compliance
HEC Engineering carries out all design stages of deep-sea outfall systems — from pipeline routing to multi-port diffuser configuration — with precise hydrodynamic analyses. Projects prepared with submarine topography, current regimes and environmental regulations in mind ensure rapid dilution of effluents and full regulatory compliance.
Hydrology · Hydraulics · Risk Assessment
HEC Engineering comprehensively analyses flood hazard at project sites by evaluating catchment hydrology, rainfall-runoff relationships and drainage infrastructure capacity together. These analyses provide a reliable technical basis for planning structural and non-structural flood mitigation measures as well as insurance and land-use decisions.
Urban Drainage · Capacity · Simulation
HEC Engineering assesses the performance and capacity of stormwater infrastructure in urban and industrial areas by analysing pipe networks, open channels and underground storage systems through an integrated modelling approach. This service covers system design for new development sites and rehabilitation planning of existing infrastructure.
Sustainable · Green Infrastructure · SuDS
HEC Engineering provides sustainable stormwater management solutions that reduce the burden on the urban water cycle. Nature-based methods such as green roofs, rain gardens, permeable pavements and bioretention basins are integrated with conventional infrastructure solutions to design projects that minimise flood and pollution risk simultaneously.
GIS · Risk Zoning · Decision Support
HEC Engineering prepares flood risk maps for different return periods by combining GIS-based analyses with hydraulic modelling results. These maps serve as a strategic data source for land-use planning, disaster management, infrastructure prioritisation and insurance applications, providing concrete decision-support tools for local authorities and project owners.
