Models

EIA 1D/2D/3D-hydrodynamic model

EIA hydrodynamic model is suitable for advanced surface water modelling applications, such as modelling dam breaks, thermal releases, or computation of surface currents for oill spill release forecasting. The model includes water quality, primary production (phytoplankton, periphyton, terrestrial flooded vegetation) and fisheries production. The model uses fully coupled nested grids for inclusion of large sea areas with high resolution local description. Density variations caused by temperature and salinity differences are taken into account. Turbulence is computed using k-e turbulence model.

EIA 3D-water quality and ecosystem model

EIA 3d water quality model works with flow data generated by the 3d hydrodynamic model. Typical applications include computation of release, transport and reactions of sediments, nutrients or other substances in inland or coastal waters. The model also allows computation of algae growth two or three algae groups, taking into account dissolved nutrients, environmental conditions and water flow. A specialized fast version of the model is used for even centuries long hydropower simulation.

IWRM hydrological model

The IWRM-model is a grid-based distributed hydrological model, that can be used to compute discharge, water quality, erosion, flooding, fish production, aquaculture, crop yields etc. in river basins.

RLGis hydrological software

The RLGis software is a tool for map-based monitoring databases, GIS-based hydrological analysis, model grid generation, and timeseries file processing.

HBV, wave and 3D air quality models

HBV is an implementation of the original Swedish lumped hydrological model for very fast simulation of watershed outflow. The wave model includes shoaling, refraction and diffraction for coastal erosion and harbour construction. The 3D air quality computes wind, stratification and air quality.
