#' 
#' @description Raster based flood modelling internally using \pkg{hyd1d}, an
#'   R package to interpolate 1d water level and gauging data. The package
#'   computes flood extent and durations through strategies originally developed
#'   for 'INFORM', an 'ArcGIS'-based hydro-ecological modelling framework. It
#'   does not provide a full, physical hydraulic modelling algorithm, but a
#'   simplified, near real time 'GIS' approach for flood extent and duration
#'   modelling. Computationally demanding annual flood durations have been
#'   computed already and data products were published by Weber (2022)
#'   <doi:10.1594/PANGAEA.948042>.
