Environmental Quality Management

Akvaplan-niva offers a variety of services for environmental quality management. We apply a broad selection of modeling tools for fjords and coastal areas that allow clients to better visualize and assess the potential consequences of on-going or planned activities and to identify ways to minimize expected environmental impacts.

Our specialists have extensive experience addressing impacts associated with managing emissions and water quality related to industrial operations or municipal waste water discharges, and harbour construction and maintenance.

Managing Emissions and Water Quality

Our specialists provide advice on issues related to the overall sustainable management of fjords and coastal water areas supported by modeling of the environmental conditions, including carrying capacity, oxygen levels and water replacement times. Model results are used as a basis to recommend optimal positioning of outlets for municipal sewage and industrial discharges and to determine requirements for waste water treatment. By modeling the dispersion and dilution of different emission scenarios, one can further assess the suitability of a location and depth for a planned discharge. Our emission and water quality modeling is normally combined with biological research to determine whether conditions in an area meet national environmental standards. Akvaplan-niva also provides modeling support services in wave modeling, sediment transport and dispersal of oil.

Harbour Construction & Maintenance

The addition of new structures, such as bridges and docks requires careful planning to prepare for and manage potential consequences for water quality, marine biota, and ship traffic. Knowledge of water current conditions- direction, strength, and variability- is crucial in the decision process. Akvaplan-niva uses a variety of hydrodynamic models to inform our clients on alternative solutions during the planning phase of their development projects. Our specialists work primarily with ROMS (Regional Ocean Modeling System), used for 2D/3D coastal modeling and RMA2 and FST2DH, used for 2D modeling of wave energy and currents in small areas, often in conjunction with marine structures.

We continuously incorporate improvements in our environmental monitoring methods based on the latest research and technological advancements. The development of models for applied problem solving is a continuous process carried out in close collaboration with the Norwegian Institute for Water Research. We adapt our modeling studies to the specific needs of each customer.
