cellBasins: Identification of the Cells within a basin

In DWBmodelUN: Dynamic Water Balance a Hydrological Model

Identification of the Cells within a basin

Description

This function identifies the cells that are within a basin. The runoff produced by those cells will be used, either to calculate the water availability or to compare the simulated variable with the observed runoff in certain streamflow gauges.

Usage

cellBasins(gruLoc, basins)

Arguments

gruLoc	raster (SpatRaster from terra, or an object convertible to it, such as a RasterLayer) that was used to build the GRUs. In this function it is used to number each cell from West to East and from North to South.
basins	polygons (SpatVector from terra, or an object convertible to it, such as a SpatialPolygonsDataFrame) comprising each one of the basins where the modeller wants to know the runoff. It must be in the same projection as the gruLoc raster.

Value

a list that comprise two dataframes. The first one, the list of cells in each of the basins contained in the shapefile (cellBasins), and second a table that associates the coordinates of each cell with the assigned number (cellTable).
