Research and development within hydrology
SMHI has a long tradition of operational hydrological modelling including forecasts of water discharge, fire hazard, design of dams and dam regulation routines, flood risk, water quality and substance transport and the effects of climate change on hydrology and water quality.
The hydrological research unit is engaged in numerous research projects, commissioned work and continuous development of the SMHI work-flow for hydrological forecasts and assessments. The work is often user-driven and performed in collaboration with external partners in Sweden, Europe or other parts of the world.
In addition, we produce open data from our computational systems and open source codes for hydrological modelling. The unit also has a number of specific scientific focus.
The hydrological research unit has commissions at national and international levels, including IAHS, International Association of Hydrological Sciences, NHF, Nordic Association of Hydrology and SHR, The Swedish Hydrological Council. –

New look on interactions between clouds and transpiration by trees in European forests
New research shows a clear link between different cloud types and the transpiration in European forests. An international team of researchers has estimated how changes in cloudiness affect the amount of moisture released by trees into the atmosphere – something that also influences Earth’s water cycle.
SMHI supports the development of a hydrological forecasting and warning service in Estonia
SMHI has started a new collaboration with the Estonian Environment Agency (ESTEA) to support the development of a national, operational hydrological forecasting and warning service in Estonia.
A strategic tripartite partnership to improve flood forecasting in West Africa and the Sahel
The United Nations Development Programme (UNDP), the AGRHYMET Regional Climate Center for West Africa and the Sahel (AGRHYMET CCR-AOS) of the Permanent Interstate Committee for Drought Control in the Sahel (CILSS), and the Swedish Meteorological and Hydrological Institute (SMHI) have established a strategic tripartite ...
