Hydrology

We provide new information, forecasts and knowledge about water resources in Sweden and world-wide, covering different spatial and temporal scales and a broad range of users. The information is used in decision support for a safe and sustainable society, water management, environmental protection and more.

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. –
