Dam Model Parameters¶

Note

It is the user's responsibility to ensure that parameter files are formatted appropriately. Note that it is possible to have multiple dams per grid cell (which will be processed in order).

The Dam Parameters serve three main purposes:

Define the large dam info
Define the small dam info
Define the dam servicing info

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

Below is a list of dam parameters.

Variable Name	Dimension	Units	Type	Number of Values	Description
service_id	[lat, lon]	N/A	int	1	Current cell grid cell ID
Ndam_local	[lat, lon]	N/A	int	1	Number of local dams in the grid cell
year_local	[dam_class, lat, lon]	year	int	Ndams	Building year of local dam
capacity_local	[dam_class, lat, lon]	hm3	double	Ndams	Capacity of local dam
inflow_fraction_local	[dam_class, lat, lon]	fraction	double	Ndams	Fraction of inflow going to the local dam reservoir
Nservice_local	[dam_class, lat, lon]	N/A	int	Ndams	Numer of service cells for local dam
service_local	[dam_class, dam_service, lat, lon]	N/A	int	Ndams, Nservice	Service cell grid cell ID
service_fraction_local	[dam_class, dam_service, lat, lon]	fraction	double	Ndams, Nservice	Fraction of demand of service cell for local dam
Ndam_global	[lat, lon]	N/A	int	1	Number of global dams in the grid cell
year_global	[dam_class, lat, lon]	year	int	Ndams	Building year of global dam
capacity_global	[dam_class, lat, lon]	hm3	double	Ndams	Capacity of global dam
inflow_fraction_global	[dam_class, lat, lon]	fraction	double	Ndams	Fraction of inflow going to the global dam reservoir
Nservice_global	[dam_class, lat, lon]	N/A	int	Ndams	Numer of service cells for global dam
service_global	[dam_class, dam_service, lat, lon]	N/A	int	Ndams, Nservice	Service cell grid cell ID
service_fraction_global	[dam_class, dam_service, lat, lon]	fraction	double	Ndams, Nservice	Fraction of demand of service cell for global dam
