Hydrology research at SMHI

The SMHI has a long tradition in operational hydrological modelling of river runoff. Existing applications cover aspects like runoff forecasting, spillway design, hydrochemical modelling and fire danger forecasts.

The SMHI hydrological research group works to develop hydrological forecasting and scenario tools, describe the hydrological consequences of climate change, modeling nutrient in rivers and biogeochemical processes in lakes.

The aim of the work is to provide better forecasting and warning services for the power industry, improved decision support for land management, environmental monitoring and action programs that help improve water quality.

Results will be used partly by SMHI and the production departments as well as directly by external users or in a purely scientific context. Several of the projects are carried out in co-operation with other research groups on a national as well as an international level.

HYPE model to support the countries around the Niger River

Heavy rainfall and dry spells are common in the countries surrounding the Niger River in West Africa. Researchers from SMHI and the AGRHYMET regional centre in West Africa have jointly developed a tool which can provide a better quantification of the hydrological fluxes in the Niger River basin. Hydrological model to support the countries around the Niger River.


Research on intense precipitation could increase preparedness upon local flooding

In recent times, abundant rainfall over southwestern Sweden has caused high water levels and flooding. An ongoing research project is developing flow forecasts which are better at capturing the effects of sudden downpours.

Summer course in hydrological modelling

Deltagare på HYPE sommarkurs 2014.

SMHI provides pan-European water information based on their hydrological model system, E-HYPE (European HYdrological Predictions for the Environment). During the summer, 20 people from six European countries gathered at SMHI to find out more about the model results. Summer course on hydrological modelling.


Future of the Baltic Sea in focus

The problems associated with eutrophication have long affected the Baltic Sea with large blooms of toxic algae, and oxygen-free bottoms. Four years of research will provide more knowledge about the future of the Baltic. SMHI Hydrology Research participates in Soils2Sea. Future of the Baltic Sea in focus


Torrential rainfall in the future

Changes in the climate are expected to result in heavier rainfall. Calculations with climate models show that a heavy downpour will give 20-30 percent more rain at the turn of the next century. Intensive short-term precipitation causes most problems in towns and cities, since it produces large quantities of rain in a short period of time. Heavier rainfall in the future.

Climate change is affecting water supply in India

In a research project, SMHI developed a hydrological model for India, in which calculations were made of water supply in the country’s future climate. The results were presented at a conference in Rajasthan recently. Climate change is affecting water supply in India 

HYPE Open Source Community develops

In HYPE Open Source Community, the hydrological model HYPE is developed. The network is unique in that it provides access to program codes that are also used in operational status. The latest international workshop on HYPE codes was held in Brussels in conjunction with the Open Water Symposium. HYPE OSC continues to develop

Open data gives water apps

Apps and web services for forecasting and decision support in the event of flooding, water contamination, irrigation and dam control. This is the aim of a European research project, SWITCH-ON, coordinated by SMHI. This is a pilot project that can make European water data more accessible to the general public and water management more mobile. Open data gives water apps
