100årsflöde refers to a flood event with a statistical probability of occurring once every 100 years. It is a term commonly used in hydrology and flood risk management. This does not mean that such a flood will happen exactly once every century, but rather that the probability of a flood of that magnitude occurring in any given year is 1%. The concept is based on statistical analysis of historical flow data for a particular river or water body.
Calculating the 100-year flood is crucial for infrastructure design, such as bridges, dams, and flood defenses,
The 100-year flood level is a benchmark for flood risk assessment. Exceeding this level implies a more
