The true probability distribution for floods at any catchment is unknown and has to be estimated. It is assumed that future floods will follow the same flood patterns as those in the past and we could derive the flood probability distribution based on the past flood records. Statistics is a branch of mathematics that helps us estimate flood frequency parameters.
