Water-use Model Parameters¶

The Water-use Parameters serve three main purposes:

• Define the cell ID number of each grid cell. This ID number is used to identify receiving cells.
• Define the receiving cells. (use in remote water withdrawals)

The water-use parameters are supplied to VIC-WUR in a NetCDF file, with a separate variable for each water-use parameter.

Below is a list of water-use parameters.

Variable Name	Dimension	Units	Type	Number of Values	Description
receiving_id	[lat, lon]	N/A	int	1	Current cell grid cell ID
Nreceiving	[lat, lon]	N/A	int	1	Number of receiving cells
receiving	[wu_receiving, lat, lon]	N/A	int	water-use max receiving	Receiving cell grid cell ID
