Use HYFO for planning of water resource management

HYFO is a customized visualization and information system with observations and forecasts that provide a good basis for decision-making in hydro-power production and water resources management.

HYFO is SMHI’s modern presentation system for hydrological and meteorological observations and forecasts. This web-based presentation tool is developed in consultation with our customers and can be customized according to your needs and preferences.

More effective water regulation

The supportive visualization system provides refined hydrological and meteorological information with the aim to:

  • Provide comprehensive hydrological information for optimal water management.
  • Provide a thorough basis for the production of hydroelectric power and dam regulation  ensuring compliance with the applicable water legislation.
  • Reduce the risk of infrastructure failure.

User-friendly web tool

Data and forecasts are delivered and presented on a web-interface. HYFO is a user-friendly web tool which easily presents indicators you need for making decisions in your business. Hydrological forecast models can be set up with HBV and HYPE and can be calibrated for any sub basin. Delivered forecasts of inflow, precipitation, temperature, snow etc. can all be presented in maps, diagrams and tables in HYFO.
