Silt Curtain & Turbidity Management
Turbidity — the suspension of sediment particles in the water column — is one of the most significant environmental impacts of dredging, land reclamation and coastal construction. Elevated turbidity can smother coral reefs, reduce seagrass productivity, impair fish feeding and respiration, and violate coastal water quality standards.
QRS provides comprehensive turbidity management services, from silt curtain design and procurement through to real-time turbidity monitoring and adaptive management — ensuring construction activities remain within permitted turbidity thresholds and minimise impacts on sensitive marine habitats.
Our Service Scope
Silt Curtain Design & Specification
Engineering design of silt curtain systems tailored to site-specific hydrodynamic conditions and dredging operations.
Turbidity Plume Modelling
Predictive numerical modelling of turbidity plumes to assess potential impacts before dredging commences.
Real-Time Turbidity Monitoring
Deployment of automated turbidity sensors with real-time data telemetry and threshold alert systems.
Silt Curtain Inspection & Maintenance
Regular underwater inspection and maintenance of silt curtain systems to ensure effectiveness throughout construction.
Turbidity Exceedance Response
Rapid response protocols and technical support when turbidity thresholds are exceeded during construction.
Post-Dredge Water Quality Assessment
Post-construction water quality monitoring to verify return to background conditions and permit compliance.
Our Deliverables
Every QRS engagement concludes with a comprehensive set of clear, professional deliverables designed to meet regulatory requirements and drive informed decision-making.
