pywr.domains.river.Reservoir

class pywr.domains.river.Reservoir(*args, **kwargs)

A reservoir node with control curve.

The Reservoir is a subclass of Storage with additional functionality to provide a simple control curve. The Reservoir has above_curve_cost when it is above its curve and the user defined cost when it is below. Typically the costs are negative to represent a benefit of filling the reservoir when it is below its curve.

__init__(model, *args, **kwargs)

Keywords:

control_curve - A Parameter object that can return the control curve position,

as a percentage of fill, for the given timestep.
