## Description

Calculate inundation frequence at height h0 from series of high water levels H

## Usage

IF(H, h0,N = length(H[,1]))

## Arguments

H

High water levels. Data Frame with column h

h0

Reference level for which IF has to be calculated

N

number of cycles in time series, equals the number of high water levels when these are complete (= default value)

## Value

Inundation frequence [%] at reference level h0
