pywr.recorders.FlowDurationCurveRecorder

class pywr.recorders.FlowDurationCurveRecorder(model, AbstractNode node, percentiles, **kwargs)

This recorder calculates a flow duration curve for each scenario.

Parameters:

modelpywr.core.Model

nodepywr.core.Node

The node to record

percentilesarray

The percentiles to use in the calculation of the flow duration curve. Values must be in the range 0-100.

agg_func: str, optional

function used for aggregating the FDC across percentiles. Numpy style functions that support an axis argument are supported.

fdc_agg_func: str, optional

optional different function for aggregating across scenarios.
