Total floodplain area

Source: R/getAreaTotal.R
getAreaTotal.Rd

Determine the total floodplain area as the number of cells where the digital elevation model (DEM, (Weber 2020) ) is submerged at the FLYS3 water level HQ100 computed with hyd1d::waterLevelFlys3() for the indexed hectometer of the River Elbe floodplain sf.afe_csa.

Usage 

getAreaTotal(x)

Arguments

x

must be a single integer indexing one hectometer polygon of sf.afe_csa along the River Elbe. x must be element of seq(from = 1, to = length(sf.afe_csa), by = 1).

Value

numeric specifying the area (m²) of the indexed hectometer.
