Water quality

Modelling of water quality in rivers and surface water bodies

Water quality in rivers and other surface water bodies are increasingly threatened by human activity, such as pollution from point and diffuse sources, physical changes in the watershed area, change in land use, poor water treatment, inefficient operation of regulation systems and leisure activities.

Solute concentrations or temperature in river systems are simulated by a combination of our hydrodynamic MIKE 11 model with advection-dispersion processes and water quality models that applies processes and reactions to pollutants throughout the river system. This combination provides unique capabilities for modelling and analysis of environmental conditions in rivers, canals and reservoirs.

Water quality processes in MIKE 11 are defined in ECO Lab, our framework for ecological modelling. It is based on a stable and powerful system for solving differential equations. ECO Lab is applied by most of our MIKE by DHI products for water quality modelling.


  • Fully dynamic, coupled simulation of hydrodynamic, solute transport and water quality processes
  • ECO lab utilise open and editable templates for water quality models
  • Predefined water quality templates provided with standard formulations for tested water quality models
  • You can easily adapt templates to local conditions
