These waves are mainly observed as variations in the sea level along the coast or when they meet the coast (tsunami). The speed of a long wave is governed by the depth, and they move faster over deep water. In a depth is 100 m, as found parts of the Baltic Sea, a long wave such as a tsunami would Last updated: Apr 23, 2014

Flood mapping is based on an inventory of existing information for the area of interest. This is often combined with measurements of flows and water levels. Based on these measurements and hydraulic models we calculate water levels and water distribution at different extreme situations. We also Last updated: Mar 13, 2024

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.

assessments of what the local seawater level will be in the future along a particular stretch of coast – and along with the various risk levels involved. Part from the international and regional climate scenarios we take into account the absolute elevation of the land, which varies along the Swedish coast Last updated: Apr 23, 2014

the bottom waters, salinity was 35 psu at the offshore stations and 33.5 psu at Släggö. The temperature in the bottom waters ranged from 11°C at Å13 to 7.4°C at Å17. Levels of dissolved inorganic nitrogen (DIN) in the surface water were around detection limit (0.1 µmol/l) at three stations. At Å15 Last updated: Dec 16, 2024
