Set active demand

Water users have one active demand and optional inactive demands.

We can specify the active demand for one or more nodes. If the specified demand is note available on a particular node, it will have no effect.



In [13]:

    
v.model.node.water_users.set_active_demand('my new timeseries demand')
# SAFE because 'my new timeseries demand' only exists on one node









    Out[13]:

Configuring demand parameters

Currently no functionality for the specific demand models...

Time series demands can be configured via 'DemandModel.Order' (assuming the time series demand is the active demand model)



In [15]:

    
v.model.node.water_users.set_param_values('DemandModel.Order',5,nodes='IrrigationOnlyForestWU')

# Note, the above will not take effect if a function is already being used. Need to cancel the function...
# v.model.node.water_users.clear_function_usage('DemandModel.Order',nodes='IrrigationOnlyForestWU')









    Out[15]:





True

Similarly, we can use assign_time_series...



In [16]:

    
# v.model.node.water_users.assign_time_series('DemandModel.Order','col','datasource',nodes='IrrigationOnlyForestWU')
