Some projects need expertise beyond that which traditional civil and environmental firms provide.
WEC delivers specialized services to help your team with:
- NPDES discharge permitting and plume modeling
- Numerical modeling of hydrodynamics, water quality, sediment transport, and wave transformation
- Coastal engineering
- Field monitoring (water levels, flows, currents, water quality)
- FEMA flood hazard mapping and LOMR applications
- Hurricane hazard modeling (extreme storm surge water levels, wind and waves) to support coastal resiliency planning
• The study incorporated extensive field measurements for tidal currents and vessel wave heights. WEC used the 2D SWAN model to establish extreme wave conditions at the site for a variety of storm scenarios and return periods. The project also included an assessment of sedimentation rates at the proposed dock facility to estimate future dredge maintenance needs.
• WEC used the CORMIX model to design a single-port diffuser resulting in favorable whole effluent toxicity limits and the EFDC model to ensure the discharge would not affect the dissolved oxygen within the river.
• The study included 6-month deployments of an Acoustic Doppler Current Profiler (ADCP) to measure tidal currents in the river and three water level gauges in the estuary. WEC also measured currents using a vessel-mounted ADCP to characterize the spatial distribution of currents beneath two bridges. The study provided high-quality, continuous current and water level measurements in the rivers over a 6-month period.
• Services included field measurements for bathymetry, current velocity, and temperature as well as multiple CORMIX modeling scenarios for various outfall configurations. The project resulted in whole effluent toxicity (WET) limitations with sufficient compliance margin for the plant expansion and addressed NPDES permit limits for future expansion plans.
• Under contract with MDB Consulting Engineers, P.A, WEC completed field measurements and water quality modeling of the proposed discharge to demonstrate the project’s compliance with state water standards, potentially saving millions in project capital costs.
• The study included high-quality, water level measurements for a period of 2-weeks.
• The data was integrated into a hydraulic model to support the City of Beaufort’s ongoing drainage improvement efforts in the Mossy Oaks neighborhood.
• WEC developed a storm surge analysis methodology to include improving the FEMA ADCIRC model for the region. WEC worked with ATM to complete the hurricane modeling analysis.
• The study results provide a more robust assessment of the storm surge and sea level rise scenarios within the upper St. Johns River and tidal tributaries, which the County can incorporate into stormwater infrastructure design.
