hydflood

The R package hydflood is designed to compute flood extents and durations along the German federal waterways Elbe and Rhine.

Installation

hydflood is currently not available from CRAN, but you can install the developmental version from Github with:

install.packages("devtools")
library(devtools)
devtools::install_github("bafg-bund/hydflood")

Usage

The package hydflood is build around the packages terra and hyd1d.

# load the package
options("hydflood.datadir" = tempdir())
library(hydflood)

# import the raster data and create a raster stack
x <- hydSpatRaster(filename_dem = "data-raw/raster.dem.tif",
                   filename_csa = "data-raw/raster.csa.tif")

# create a temporal sequence
seq <- seq(as.Date("2016-12-01"), as.Date("2016-12-31"), by = "day")

# compute a flood duration
fd <- flood3(x = x, seq = seq)

# and plot it
plot(fd)
