Future seawater levels

seawater levels are specific to one area. To obtain a possible image of future seawater levels in Swedish waters we use the results from the latest IPCC report and from other relevant research. We also take into consideration the elevation of the land, which varies along the Swedish coast. Our assessments Last updated:

A wave breaks when the depth is less than 1.3 times the wave height. After a wave has broken, it keeps moving forward while continuing to break. After a certain distance Last updated:
