Wind Power At SeaFor establishment of wind power plants at sea, careful investigations are needed. The load on the power plants is great from the wind, waves, currents and ice, and the costs for maintenance is closely related to the weather. In addition, there are often external requirements, such as environmental regulations, to take into account. |

HBV/IHMSThe HBV model is a well-known model for the calculation and modelling of flows. The calculations are carried out on a calibrated river with observations for water level and volume of discharge and with observations and forecasts for precipitation and temperature. IHMS is the user interface which makes the modelling work easier. |

European Hydrological Predictions For The EnvironmentA first version of a Pan-European hydrological model (E-HYPE) with high resolution is operational in the SMHI production environment. So far, the model is uncalibrated and based on readily available global databases, which also reflects the uncertainty, but the infrastructure is now available and open for improvements. |
