Flood-risk maps are the primary tool that guides the sensible use of flood-prone lands. They indicate flood-risk areas. The maps may also show the "20-year flood" and "100-year flood" levels (generally accepted terms for the statistical likelihood that every year there is a five per cent chance of the 20-year flood occurring, and a one per cent chance of the 100-year flood occurring at that location .... Like other natural events, floods seem to occur in long-term cycles. Consequently, by studying streamflow records over many years, we can estimate the probability of a dangerously high flow. This can be expressed either as a percentage or as a recurrence interval. For example, we may say a flood has a one-per-cent chance of occurring in any year, or we may call it a one-in-a-hundred year flood.

Les cartes des risques d'inondation peuvent illustrer les niveaux des crues à récurrence de 20 ans et de 100 ans (termes généralement reconnus pour représenter la probabilité statistique qu'il y a, chaque année, 5 % de chances qu'une crue à récurrence de 20 ans survienne et 1 % de chances qu'une crue à récurrence de 100 ans se produise à cet endroit). (...) La probabilité d'une montée dangereuse des eaux pourra être évaluée soit en pourcentages, soit en intervalles de récurrence. On dira , par ex., qu'une inondation a 1 % de chance de se produire n'importe quelle année ou on la désignera sous le nom d'inondation de cent ans.

(...) on appelle "crues décennales, centenaires, ou millénaires", les plus fortes crues qu'il existe une probabilité de 1/10, 1/100 ou 1/1000 de voir apparaître dans l'année (...). On organise généralement la défense contre les inondations sur la base des "crues décennales" ou "centenaires", sauf lorsqu'il y a risque de morts en grand nombre (...), où l'on s'équipe alors sur la base des "crues millénaires" voire "sentamillénaires". 4, record 1, French, - crue%20d%C3%A9cennale
