buildGRUmaps: Build Grouped Response Units in maps

In DWBmodelUN: Dynamic Water Balance a Hydrological Model

Build Grouped Response Units in maps

Description

This function builds raster maps for each parameter based on a raster file where the location of the Grouped Response Units (GRUs) are defined. This raster must have the same resolution as the forcing files (i.e., for each cell that is planned to be simulated, there must be forcing time series and a cell assigned to a GRU).

Usage

buildGRUmaps(gruLoc, parsValues)

Arguments

gruLoc	raster (SpatRaster from terra, or an object convertible to it, such as a RasterLayer) that is comprised by numbers from 1 to the total number of GRUs that were defined.
parsValues	data frame or matrix that has the values of the four parameters of each GRU. It must have equal number of rows as number of GRU that were defined, and must have four columns which define the alpha1, alpha2, d and Smax parameters, in that order.

Value

a list which consists of four vectors (alpha1, alpha2, d, smax) and four SpatRaster objects (alpha1R, alpha2R, dR, smaxR), each one of them with the values of a parameter spatialized according to the GRU raster layer.
