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.
What people are saying about us
”“WEC has provided a high level of service and has consistently met our high expectations. I particularly value WEC’s technical and regulatory expertise in approaching and addressing a wide range of issues with DHEC.”Paul CalamitaChainman, AquaLaw
”“Mr. Goodrich integrated seamlessly within the Corps team, and his participation in brainstorming and problem solving exercises was critical in overcoming challenging technical concepts. His expertise, professionalism and work ethic contributed greatly to the delivery of a quality project that met the aggressive timeline for completion. I would highly recommend Mr. Goodrich and Water Environment Consultants for other projects requiring environmental and water resources expertise.”Brian Williams, P.E.Assistant Chief of Programs and Project Management Division, US Army Corps of Engineers Charleston District
”“WEC’s assistance on the modeling project was critical to avoiding significant field data collection costs (as included in the permit) and negotiation with SCDHEC to obtain permit limits amenable to both parties. The project was executed under a tight time frame and was executed in a very professional manner. I would not hesitate to recommend Water Environment Consultants to others for projects requiring environmental and water resources consulting expertise.”Gary Alford, P. E.Former Chief Operating Officer, North Charleston Sewer District
