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.

Summer course in hydrological modelling

Participants at the Summer Course 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.

Future of the Baltic Sea in focus

FoUh deltar i Bonsuprojektet Soils2Sea

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

Regn - Cumulonimbus

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

India-HYPE konference 2013 vattentillgång projektgrupp

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

World of HYPE

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

Översvämning i Värnamo

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
 

New Workshop for HYPE Open Source Community in September.

Welcome to a new workshop for HYPE OSC the 18th of September. The workshop will be organized in connection to the Open Water Symposium at Vrije Universiteit in Brussels. We will present new features of HYPE and we will also give the opportunity for users to present their work using HYPE

New research program: Baltic Earth

Baltex 7

A new international and interdisciplinary research programme, Baltic Earth, is launched. The aim of Baltic Earth is to achieve an improved understanding of the Earth system for the Baltic Sea region, focusing on physical and biogeochemical processes which interact in the atmosphere, in the sea including sea ice, and on land.

Europe's discharge of nitrogen and phosphorus calculated

Total mängd kväve (ton/år) samt källfördelning

Agriculture discharges the most nitrogen into Europe's coastal seas. Discharges of phosphorus come from treatment works to a larger extent, although in some areas agriculture and forestry are responsible for large discharges. This is shown by a study carried out by scientists at the Hydrology Research Unit, SMHI.

The hidden water content of the snow layer

Karta med snötäckningsgrad 1 april 2013

Satellite measurements can show the extent and water content of the snow coverage, and where it will melt. Scientists from SMHI are part of the European research project (Cryoland) aiming to develop new, simpler ways of using satellite data about snow and ice.
