Area of the submerged active floodplain at MQ

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

Usage

getAreaBelowMQ(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 an area (m²).
