pywrdrb.parameters.LowerBasinMaxMRFContribution

class pywrdrb.parameters.LowerBasinMaxMRFContribution(model, reservoir, step, nodes, parameters, **kwargs)

Used to track the max of allowable release from a lower basin reservoir based on policy and current conditions.

If predicted Trenton flow > flow target, then max allowable release is 0.0 (no contribution needed). If predicted Trenton flow < flow target, then max allowable release is determined by: - the current storage of the reservoir - the priority level of the reservoir, as described in WaterCode.

This is provided to VolBalanceLowerBasinMRFAggregate to determine the aggregate MRF contribution from the lower basin reservoirs.

__init__(model, reservoir, step, nodes, parameters, **kwargs)

Initialize the LowerBasinMaxMRFContribution parameter.

Parameters:

• model (Model) – The pywrdrb.Model instance.

• reservoir (str) – The name of the reservoir, e.g. “blueMarsh”, “beltzvilleCombined”, “nockamixon”.

• step (int) – The step of the Trenton flow calculation (1-4). See pywrdrb.parameters.ffmp for more.

• nodes (dict) – Dictionary of pywrdrb.nodes.Reservoir instances for each lower basin reservoir. Format {“reservoir_name”: pywr.Node}.

• parameters (dict) – Dictionary of pywrdrb.parameters.Parameter instances for each lower basin reservoir. Format {“parameter_name”: pywr.Parameter}.

• **kwargs (dict) – Additional keyword arguments to pass to the pywr.Parameter class. None used.

Return type:

None
